What Does UFO Polling Data Reveal About How Public Beliefs Have Changed?

Key Takeaways

• Belief in extraterrestrial life is common, but percentages depend strongly on question wording.
• Suspicion of government secrecy has remained high for decades rather than following a simple upward trend.
• National, expert, commercial, experiential, and self-selected surveys answer different questions.

What UFO Polling Data Actually Measures

A CBS News/YouGov survey conducted from June 2 through June 4, 2026, among 2,023 American adults found that 63% believed intelligent life exists on other planets, 21% believed humanity had already made contact with intelligent extraterrestrial life, 17% said they had seen something they thought was an unidentified flying object (UFO), and 84% thought the United States government knew more about UFOs than it was telling the public.

Those four percentages demonstrate why UFO polling data cannot be reduced to one measure of belief. Believing intelligent life exists somewhere beyond Earth differs from believing extraterrestrials have visited Earth. Both differ from reporting an unexplained personal sighting. Suspecting that a government possesses undisclosed information represents another attitude again.

The UAP News Center polling collection provides a useful starting point for locating polls, academic studies, media surveys, infographics, historical material, and international polling concerning UFOs, unidentified anomalous phenomena (UAP), extraterrestrial life, personal sightings, alien visitation, and government disclosure.

For statistical analysis, the material can be organized according to the date respondents were actually surveyed rather than the date an article, infographic, retrospective, or research paper was published. Multiple articles discussing the same fieldwork can also be treated as one underlying survey rather than as separate measurements.

That approach produces a cleaner chronology and preserves the distinction between primary polling and later interpretation.

It also separates several populations that appear in the wider polling literature. Nationally representative surveys estimate attitudes among the general population. Registered-voter surveys describe voters. Academic studies can examine scientists or university faculty. Commercial surveys may use different sampling methods. Audience surveys and open website polls describe the people who chose to participate.

All of those sources can illuminate some aspect of the UAP subject. They do not estimate the same population.

Question wording matters just as much as sampling.

“Do you believe intelligent life exists on other planets?” tests a proposition compatible with contemporary astronomy and the enormous number of planets now known to exist.

“Are some UFOs alien spacecraft?” requires respondents to connect extraterrestrial intelligence to reported observations on Earth.

“Have extraterrestrials visited Earth?” adds the proposition that extraterrestrial beings or technology have crossed interstellar distances and reached this planet.

“Have you ever seen something you thought was a UFO?” records an observer’s classification of an experience. It does not determine the cause of the observation.

“Does the government know more than it is telling the public?” measures institutional trust and expectations concerning secrecy as much as beliefs about the physical origin of UAP.

These questions often produce markedly different percentages even when asked within the same survey.

The distinction also separates public opinion from evidence concerning UAP themselves. Government investigations, scientific research, military reports, and public polling address different subjects. A survey can establish what respondents believe, suspect, remember, or report. It cannot determine what produced a particular physical observation.

The long polling record does show change in some measures. Gallup’s directly repeated question concerning alien spacecraft increased from 33% in 2019 to 41% in 2021. Acceptance of intelligent extraterrestrial life appears substantially more common in modern surveys than it was in older polling. Government secrecy measures have remained high for decades. Personal-sighting percentages fluctuate considerably depending on wording and methodology.

The most consistent pattern is hierarchical. Belief that extraterrestrial life exists somewhere usually attracts the broadest support. Belief that extraterrestrials have visited Earth attracts less. Attribution of specific UFOs to extraterrestrial technology can be lower still. Personal sightings involve a smaller portion of the population. Suspicion of government secrecy can exceed all of those measures because it does not necessarily require belief in extraterrestrial visitation.

Early Polling Established Several Distinct Types of UFO Belief

1966 Gallup Flying Saucer Polling

Gallup polling conducted from April 14 through April 19, 1966 provides one of the earliest useful national benchmarks.

A later Gallup Vault retrospective reported that 96% of Americans had heard or read about flying saucers. Approximately 5% said they personally had seen something they thought was a flying saucer.

Among people familiar with the subject, 46% thought reported objects represented something real rather than imagination. Far fewer assigned those observations an extraterrestrial origin. Gallup reported that about 7% interpreted them as vehicles or objects from outer space.

Other respondents suggested experimental aircraft, meteors, weather balloons, or atmospheric phenomena.

The distinction remains useful decades later. Accepting that someone observed a real object does not require accepting an extraterrestrial explanation.

Modern UAP discussions frequently involve the same separation. An observation can remain unidentified because available information is inadequate without the object being extraterrestrial.

The 5% personal-sighting result also provides an early reference point, although it cannot be compared mechanically with modern UFO questions. “Flying saucer” carried a more specific visual implication than contemporary “UFO” or “UAP.” Reporting behavior, public familiarity, aviation traffic, satellites, drones, cameras, and cultural expectations have also changed considerably since 1966.

Gallup’s Historical Extraterrestrial Visitation Series

Gallup later asked Americans whether they believed extraterrestrial beings had visited Earth at some time in the past.

The proportion accepting extraterrestrial visitation stood at approximately 27% in 1990, increased to 33% in 2001, and declined to 24% in 2005.

The 2005 Gallup paranormal-belief survey, conducted June 6 through June 8 among 1,002 adults, found 24% believing extraterrestrial beings had visited Earth, 51% rejecting the proposition, and approximately 24% uncertain.

This series demonstrates that alien-visitation belief did not rise continuously.

It also illustrates why general extraterrestrial-life polling should remain separate. A respondent can regard life elsewhere in the universe as probable and still believe that no extraterrestrial civilization has reached Earth.

Government Secrecy Was Already a Majority View in the 1990s

Government disclosure represents one of the longest-running UFO opinion themes.

Gallup found in 1996 that 71% of Americans thought the United States government knew more about UFOs than it was telling the public.

When Gallup repeated the comparison in 2019, the result was 68%.

The difference over approximately 23 years was small. The comparison shows that widespread suspicion concerning incomplete government disclosure existed long before congressional UAP hearings, contemporary military videos, or widespread use of the term UAP.

This historical result becomes important when evaluating modern polls showing large majorities expecting government secrecy. High contemporary percentages do not necessarily represent the appearance of a new attitude.

2017 YouGov Polling After the TRAPPIST-1 Discovery

NASA’s announcement of seven roughly Earth-sized planets orbiting TRAPPIST-1 created an opportunity to ask Americans about extraterrestrial life in a specific astronomical context.

A February 2017 YouGov survey found approximately 40% thought the newly discussed planets were likely to contain some form of extraterrestrial life, compared with 16% who thought they probably did not.

Because the question concerned a specific planetary system, the 40% figure should not be treated as a national estimate of belief that extraterrestrial life exists somewhere in the universe.

YouGov also explored expectations concerning advanced civilizations. About 29% thought advanced aliens would be friendly, compared with 19% expecting hostility.

Approximately 12% believed contact with alien life had already occurred and that the United States government was hiding it.

That last result is substantially narrower than asking whether the government possesses undisclosed UFO information. A respondent could suspect that authorities hold classified UAP material without believing officials have confirmed extraterrestrial contact.

2017 Contact Ethics Polling

A separate 2017 YouGov survey presented Americans with a hypothetical future in which humans encountered a technologically less advanced alien civilization.

Approximately 34% favored befriending the civilization and helping it advance. About 29% favored noninterference.

This was primarily a survey of hypothetical contact ethics rather than a measurement of current UFO belief.

Its value lies in demonstrating how extraterrestrial polling had already expanded beyond existence questions into public attitudes toward future contact, communication, risk, and ethics.

By the end of this early period, several separate strands of public opinion were visible: belief that extraterrestrial life exists, belief that extraterrestrials have visited Earth, personal reports of unidentified observations, interpretations of UFOs, expectations of government secrecy, and attitudes toward hypothetical contact.

Those strands continue through the modern polling record.

The 2019 to 2021 Period Produced the Strongest Comparable Modern Trend Data

July 2019 YouGov Government Secrecy Polling

A July 2019 YouGov survey asked Americans how likely it was that the government knew something about UFOs that it was not sharing publicly.

Approximately 28% said “very likely” and 26% said “somewhat likely,” producing a combined 54%.

Political differences were limited. YouGov reported 62% among Democrats, 51% among Republicans, and 50% among independents considering undisclosed government UFO information likely.

The survey also referenced earlier research showing that only about 14% believed humanity had already contacted alien life and that government was covering up the contact.

The difference between 14% and 54% is instructive. “Government knows something about UFOs” is a much less demanding proposition than “government has confirmed extraterrestrial contact.”

September 2019 Gallup

Gallup produced several useful measures in 2019.

Approximately 68% said the government knew more about UFOs than it was telling the public, close to the 71% Gallup had recorded in 1996.

About 16% said they personally had seen something they thought was a UFO.

Among respondents discussing reports generally, 56% thought witnesses had seen something real rather than imagined something, compared with 47% in 1996.

Gallup also found approximately 75% believing that life of some form exists beyond Earth. The percentage fell to 49% when respondents were asked about “people somewhat like ourselves” elsewhere in the universe.

That 26-point difference demonstrates how the implied complexity of extraterrestrial life changes answers.

Microbial life requires a smaller inferential step than technologically capable intelligent beings.

August 2019 Gallup Alien-Spacecraft Question

Gallup then asked Americans to choose between broad explanations for UFO sightings.

About 33% said some UFO sightings had been alien spacecraft visiting Earth from other planets or galaxies.

Approximately 60% said all UFO sightings could be explained by human activity or natural phenomena.

This question became unusually valuable because Gallup repeated it two years later using substantially the same formulation.

Repeated wording provides stronger evidence of change than comparing percentages from unrelated pollsters.

June 2020 YouGov

A YouGov survey conducted June 26, 2020 asked 8,339 American adults what government would do if it possessed evidence of UFOs.

Approximately 56% said government would hide the evidence.

About 22% expected government to tell the public, and 22% did not know.

This question is hypothetical. Gallup’s government-secrecy question instead asked whether government presently knew more than it disclosed.

The percentages consequently measure related attitudes but should remain separate.

May 2021 YouGov on Terrestrial Explanations

On May 26, 2021, YouGov asked 7,680 United States adults whether UFOs or UAP could be explained by earthly activities such as human actions or natural occurrences.

About 16% said they could always be explained terrestrially, 33% said they usually could, 17% said they usually could not, 8% said they never could, and 27% were uncertain.

The distribution shows that public attitudes were not divided neatly into extraterrestrial believers and terrestrial skeptics.

Approximately 49% leaned toward terrestrial explanations in all or most cases. About 25% leaned against terrestrial explanations for most or all cases. More than one-quarter remained uncertain.

May 2021 Economist and YouGov

An Economist/YouGov survey conducted from May 22 through May 25, 2021 found approximately 61% of American adult citizens saying intelligent life definitely or probably existed on another planet.

About 19% said they personally had seen something they thought was a UFO.

Approximately 65% thought the government was not honest with the public about UFOs, compared with 11% who believed it had disclosed everything it knew.

About 66% supported government agencies investigating reports of unidentified objects.

The combination is informative. Respondents could distrust government disclosure and simultaneously support government investigation.

June 2021 Pew Research Center

Pew Research Center surveyed 10,417 United States adults from June 14 through June 24, 2021 through its American Trends Panel.

Approximately 65% said their best guess was that intelligent life exists on other planets.

The result closely resembled YouGov’s 61% measurement from the preceding month despite methodological and wording differences.

Pew then asked whether UFOs reported by people in the military represented evidence of intelligent life outside Earth.

Approximately 51% said the reports were definitely or probably such evidence, including 11% saying definitely and 40% saying probably.

About 47% did not regard the reports as likely evidence of extraterrestrial intelligence.

The gap between 65% accepting intelligent extraterrestrial life and 51% associating military UFO reports with it illustrates the recurring distinction between cosmic-life belief and UAP attribution.

Threat perception was much lower.

Approximately 51% said reported UFOs posed no national-security threat at all. Another 36% regarded them as a minor threat. Only about 10% considered them a major threat.

Pew also examined religious differences using the same June survey. Those findings represent demographic analysis of the same underlying fieldwork rather than another national measurement.

2021 Gallup and the Strongest Short-Term Trend

Gallup’s repeated alien-spacecraft question supplies one of the most informative changes in the entire polling record.

In 2019, 33% said some UFOs had been alien spacecraft.

By 2021, the percentage had increased to 41%.

The proportion saying all UFO sightings could be explained through human activity or natural phenomena fell from 60% to 50%.

The eight-point increase is persuasive because Gallup used the same underlying proposition and the same polling organization conducted both measurements.

It does not mean that 41% believed every UFO was extraterrestrial. Respondents needed to believe only that some sightings represented alien spacecraft.

The surveys alone cannot determine what caused the increase.

The interval included intensive media coverage of United States Navy videos, official acknowledgment of UAP investigations, congressional interest, and release of the June 2021 intelligence assessment.

Those developments form the surrounding cultural and political context, but they do not provide experimental proof that any one event caused the attitudinal shift.

The 2019-to-2021 Gallup comparison nevertheless remains among the strongest pieces of evidence that willingness to entertain an extraterrestrial explanation for at least some UFO reports increased during this period.

The 2022 Polls Expanded the Range of Questions

May 2022 Morning Consult

Morning Consult surveyed 2,005 registered voters from May 20 through May 22, 2022.

Approximately 62% believed extraterrestrial life exists.

That result closely resembles the 61% YouGov and 65% Pew measurements from 2021, although Morning Consult surveyed registered voters rather than all adults.

Belief differed by political and demographic group.

Approximately 68% of Democrats, 62% of independents, and 55% of Republicans accepted extraterrestrial life.

Younger adults were more likely to believe. Morning Consult reported approximately 76% among Generation Z adults and 72% among millennials, compared with 59% among Generation X and 54% among baby boomers.

Another statistic requires attention to the denominator.

Morning Consult reported that 79% of respondents who already believed extraterrestrial life exists also believed the government had concealed the existence of UFOs from the public.

The 79% result applies to the subset of extraterrestrial-life believers, not to all registered voters.

Roswell Belief

Fairleigh Dickinson University polling associated with the 75th anniversary of the Roswell incident asked Americans how plausible they considered the proposition that an extraterrestrial spacecraft crashed near Roswell, New Mexico.

Approximately 34% regarded the extraterrestrial explanation as at least plausible, including 12% considering it very likely.

Roswell belief belongs in a separate category from general extraterrestrial-life belief.

A respondent may believe intelligent civilizations exist elsewhere and reject the proposition that one crashed in New Mexico. Another respondent might remain uncertain about extraterrestrial life generally but consider a specific historical claim possible.

Named incidents need their own trend category.

MyVision Commercial Survey

MyVision surveyed 1,013 Americans in 2022 concerning UFO experiences, extraterrestrial beliefs, and government knowledge.

More than one in 10 respondents reported seeing a UFO firsthand.

Approximately 56% believed aliens had visited Earth.

About 64% thought extraterrestrials knew Earth or humanity existed.

Approximately 37% believed scientists or officials had already made contact.

Government-knowledge responses were high, with 73% saying government knew more than it disclosed.

The survey sampled respondents aged 18 through 80 and published demographic characteristics. Its documentation differs from the probability-based methods used by organizations such as Pew and Gallup, so it is most useful as a commercial survey snapshot rather than as a precision national trend benchmark.

September 2022 YouGov

A YouGov survey conducted September 9 through September 12, 2022 among 1,000 United States adult citizens found Americans almost evenly divided among three broad positions.

Approximately 34% said UFOs were likely alien ships or alien life forms.

About 32% favored natural or scientific explanations.

Another 34% were uncertain.

Approximately 24% said they had seen something they thought was a UFO.

Among those self-reported witnesses, only 34% attributed the experience to aliens. Approximately 43% favored a natural or terrestrial explanation, and 23% remained uncertain.

This result demonstrates that “UFO witness” is not synonymous with “alien witness.”

People can experience an observation they cannot initially identify and subsequently favor a terrestrial explanation.

2022 Secondary Visualizations

Several New Space Economy infographics published during this period present polling and reporting data concerning American beliefs, British beliefs, alleged UFO shapes, and related subjects.

For trend analysis, such visualizations are best assigned to the field date of the underlying survey or dataset when that information is available.

An infographic based on 2021 polling remains evidence concerning 2021 public opinion even when the visualization itself appears in 2022.

The same principle applies to later media graphics and retrospective articles.

Publication date describes when information was presented. Field date describes when respondents expressed the opinion.

That distinction keeps the statistical timeline internally consistent.

The 2023 and 2024 Surveys Examined Experts, Sightings, Disclosure, and Official UAP Activity

University Faculty Research

Research published in Humanities and Social Sciences Communications surveyed 1,460 tenured and tenure-track faculty members in 14 academic disciplines at 144 American research universities.

The University of Louisville-led study examined academic attitudes toward UAP rather than national public opinion.

Nearly one-fifth reported that they or someone close to them had observed something they interpreted as a UAP of unknown origin.

The study also found substantial interest in more academic research concerning UAP and willingness among some faculty to participate in such work.

This population should remain separate from general-public surveys.

A faculty survey can measure scholarly interest, academic stigma, willingness to conduct research, personal experience, and perceptions of institutional legitimacy.

It cannot estimate the percentage of all Americans who hold those views.

July 2023 Ipsos

Ipsos conducted a nationally representative KnowledgePanel survey of 1,019 United States adults from July 14 through July 16, 2023.

Approximately 42% said they believed in UFOs.

About 10% said they personally had seen a UFO.

The phrase “believe in UFOs” is broader and less precise than Gallup’s proposition that some UFOs were alien spacecraft.

The numerical proximity between Ipsos’s 42% and Gallup’s 41% should consequently not be interpreted as identical measurements.

Ipsos also placed the UFO item within broader polling concerning supernatural and paranormal beliefs, which can influence how respondents frame the question.

2023 Government-Disclosure Polling

Several 2023 surveys examined whether the public believed authorities possessed information that had not been released.

A Redfield and Wilton Strategies survey of approximately 1,500 eligible voters found about 57% saying government possessed more information concerning UFOs and extraterrestrial life than it had made public.

A NewsNation and Decision Desk HQ survey found more than 63% believing government had more information concerning extraterrestrial life than it had disclosed.

A separate J L Partners survey conducted for the Daily Mail found more than seven in 10 respondents believing the Biden administration was withholding UFO-related information.

These results consistently show substantial suspicion.

They should not be treated as one continuous numeric series because the questions differed.

One asks about government generally. Another refers to extraterrestrial information. Another names the incumbent presidential administration.

The common conclusion is narrower: distrust concerning public disclosure remained widespread during 2023.

March 2024 Economist and YouGov

An Economist/YouGov survey conducted March 10 through March 12, 2024 among 1,559 United States adult citizens found more than 60% believing government concealed information about UFOs.

Only about 11% thought government had told the public everything it knew.

Approximately 32% said UFOs could always be explained by human activity or natural phenomena.

Another 32% said UFOs might sometimes be alien spacecraft.

About 18% reported personally seeing something they thought was a UFO.

The survey was conducted during a period of renewed official attention to UAP, including publication of a Pentagon historical review.

That context makes the survey useful for understanding public attitudes during contemporary government disclosure debates.

March 2024 YouGov Aliens and UFOs Survey

A separate YouGov survey conducted March 8 through March 13, 2024 among 1,032 adult citizens examined extraterrestrial existence, sightings, UFO explanations, and expectations of future contact.

Approximately 53% said aliens definitely or probably exist.

About 29% thought UFOs were probably aliens.

Approximately 40% favored a natural scientific explanation, and 31% were uncertain.

About 20% said they had personally seen something they thought was a UFO.

Among those witnesses, approximately 32% interpreted their experience as alien-related, 40% favored an unknown natural explanation, and 29% remained unsure.

Again, many people who call an observation a UFO do not interpret it as extraterrestrial.

The survey also examined future contact.

Approximately 19% thought contact with extraterrestrial life would definitely or probably occur within 10 years.

The percentage increased to approximately 31% within 50 years and about 42% within 100 to 200 years.

Longer time horizons made respondents more willing to anticipate contact.

Open Web and Special-Interest Polling

Open website polls and surveys of audiences with established paranormal interests offer another category of information.

A Washington Times web poll recorded a very large majority saying they did not trust the Pentagon to tell the truth about UFO reports.

HiggyPop surveyed 370 participants drawn from an audience oriented toward paranormal subjects and found high levels of UFO belief and government-secrecy expectations.

Such results describe their participating audiences.

They should remain outside nationally representative population trends because participants select themselves into the survey rather than being sampled to represent the adult population.

This does not make those results unusable.

They can reveal the attitudes of highly engaged UFO or paranormal communities and help document how strongly those communities differ from general-public samples.

The 2025 and 2026 Record Shows a Stable Hierarchy of Beliefs

Scientist Survey Published in 2025

Research published in Nature Astronomy in January 2025 examined scientists’ views concerning extraterrestrial life.

The study included 1,055 scientists, including 521 astrobiologists and 534 scientists outside astrobiology.

Approximately 86.6% of surveyed astrobiologists agreed or strongly agreed that extraterrestrial life of at least a basic form was likely to exist somewhere in the universe.

Agreement among scientists outside astrobiology reached approximately 88.4%.

Support declined as the proposition became more demanding.

Agreement concerning complex extraterrestrial life was lower, and agreement concerning intelligent extraterrestrial life fell to roughly the upper-50% range.

The study is an expert-opinion benchmark.

It does not indicate that comparable percentages of scientists think UAP are extraterrestrial vehicles. The research concerns the probability of life elsewhere in the universe.

That distinction parallels public polling. Acceptance declines as questions move from basic extraterrestrial life to intelligent life, visitation, contact, or specific UAP attribution.

April 2025 NewsNation and Decision Desk HQ

Polling conducted from April 23 through April 27, 2025 among 1,448 registered voters found approximately 44% believing the United States government was hiding information concerning the existence of UFOs.

About 28% disagreed, and 28% were uncertain.

Younger respondents expressed the belief more frequently than older respondents.

Approximately 49% of Generation Z and 48% of millennials agreed, compared with roughly 34% of baby boomers.

The wording is relatively specific. It asks whether government is hiding information concerning the existence of UFOs rather than whether authorities possess more information than they have publicly disclosed.

The narrower wording helps explain why the result should be treated separately from broader secrecy questions that produce higher percentages.

2025 Gallup Paranormal Polling

Gallup polling conducted in May 2025 examined a collection of paranormal beliefs.

The published findings showed continuing public belief in psychic or spiritual healing, ghosts, and other paranormal phenomena.

The survey provides useful cultural context for UFO attitudes but does not supply a directly repeated 2025 measurement of Gallup’s 2019 and 2021 alien-spacecraft question.

It is therefore best categorized as adjacent paranormal-opinion research rather than as another point in the UFO-origin trend.

November 2025 YouGov

A November 2025 YouGov survey questioned 1,114 United States adult citizens.

Approximately 56% said aliens definitely or probably exist.

About 47% believed aliens had definitely or probably visited Earth at some point.

Approximately 42% thought aliens had visited Earth in relatively recent times.

Only about 30% thought UFOs were probably alien ships or alien life forms.

Approximately 45% favored another explanation, leaving the rest uncertain.

Those results establish a clear internal hierarchy within one survey.

The largest group accepted extraterrestrial existence.

A smaller group accepted visitation.

A still smaller group interpreted UFOs as alien craft or life forms.

About 21% said they personally had seen something they thought was a UFO.

Among self-reported witnesses, approximately 28% interpreted the observation as alien-related, compared with about 48% favoring another explanation.

The survey also asked about future contact.

Approximately 16% expected contact within 10 years, 29% within 50 years, 42% within 100 years, and 46% within 200 years.

Longer horizons increased expectations, but almost half of respondents still did not expect contact even over a 200-year timeframe.

Government secrecy produced one of the survey’s largest majorities.

Approximately 73% said government would hide evidence if it possessed evidence of UFOs, compared with 13% expecting disclosure.

That finding again measures anticipated institutional behavior rather than direct belief that such evidence presently exists.

Highly Educated and Science-Engaged Sample

A research study by Yonatan Eldadi, Moshe Tenenbaum, and Avi Loeb surveyed 6,114 highly educated and scientifically engaged participants.

Approximately 77.6% held at least a bachelor’s degree, and around 68% described themselves as highly or very highly engaged with science.

About 95% believed extraterrestrial intelligent life exists.

The percentage is much higher than representative national public polls, which is consistent with the distinctive composition of the participant population.

The study also examined perceptions of expert opinion and how information about scientific views affected participant attitudes.

It is most useful as research into belief formation and perceptions of scientific consensus within a science-oriented population.

It should remain separate from general-population prevalence estimates.

January 2026 Research Synthesis

Astronomer Chris Impey’s work on public belief in extraterrestrial intelligent life synthesizes polling and extensive educational survey experience.

The work describes a broad pattern in which roughly two-thirds of American adults accept intelligent extraterrestrial life, with a smaller portion believing contact has already occurred.

As a synthesis rather than a new representative national polling wave, its value lies in interpreting the accumulated record rather than supplying another chronological percentage.

February 2026 Visual Capitalist

A Visual Capitalist graphic published in February 2026 presented alien-belief data alongside belief in Bigfoot, the Yeti, the Chupacabra, and the Loch Ness Monster.

Its alien figures derive from the November 2025 YouGov survey.

Approximately 18% said aliens definitely exist and 38% said they probably exist, producing the same combined 56% recorded in the underlying YouGov survey.

For chronological purposes, the statistics belong to the November 2025 field period.

The February 2026 graphic is best understood as a later visualization of those findings.

June 2026 CBS News and YouGov

The most recent major United States national survey in this chronology was conducted by CBS News and YouGov from June 2 through June 4, 2026.

The sample included 2,023 adults.

Approximately 63% believed intelligent life exists on other planets.

CBS’s historical comparisons indicate that acceptance has become more common than in its older polling, including a 2010 survey in which fewer than half accepted intelligent extraterrestrial life.

Only 21% in 2026 believed contact with intelligent life from other planets had already occurred.

The 42-point difference between existence and contact is one of the clearest demonstrations of how strongly the measured percentage depends on the proposition.

Approximately 17% reported having seen something they thought was a UFO.

That result is close to Gallup’s 16% in 2019 and the 18% Economist/YouGov measurement in 2024.

Government-disclosure skepticism reached 84%.

Respondents said the United States government knew more about UFOs than it was telling the public.

The result is higher than many earlier measurements, although the safest interpretation is that it represents an exceptionally high reading for this specific wording rather than a directly measured increase from every earlier secrecy poll.

CBS also found approximately 30% saying government-released information had made them more likely to believe aliens had visited Earth.

Among respondents who had watched government-released videos, the percentage reached approximately 40%.

This finding suggests that official UAP material has become part of the cultural environment influencing beliefs.

It does not by itself demonstrate causation because people already interested in UAP may be more likely to seek out released videos.

The 2026 survey preserves the same broad hierarchy seen repeatedly throughout the record: majority belief in extraterrestrial intelligence, lower belief in completed contact, minority self-reported sightings, and very high suspicion concerning government disclosure.

International Surveys Show Similar Categories but Different Percentages

United Kingdom Polling

YouGov polling in Britain has found approximately half of respondents accepting the existence of aliens under some formulations.

A smaller share, around 22% in one 2021 survey, believed aliens had reached Earth.

Approximately 7% said they personally had seen a UFO.

Government secrecy received higher agreement.

About 49% thought the British government was likely to possess secret knowledge concerning UFOs, and approximately 62% said government would hide evidence if it possessed it.

The general structure resembles United States polling.

Belief in extraterrestrial existence exceeds personal sightings. Belief in visitation is lower than broad extraterrestrial belief. Suspicion concerning government disclosure can attract larger shares than either.

United Kingdom Life-Elsewhere Tracker

A September 2022 YouGov tracker measurement found approximately 73% of Britons considering it likely that some form of life exists elsewhere in the universe.

“Some form of life” includes microbial organisms and should consequently be compared with similarly broad questions rather than with surveys asking specifically about intelligent civilizations.

This distinction explains why broad astrobiological questions often generate the highest extraterrestrial-life percentages.

Beavertown and OnePoll United Kingdom Survey

A commercially commissioned OnePoll survey of 2,000 United Kingdom adults asked respondents about unusual observations in the sky and extraterrestrial beliefs.

Approximately 37% reported having witnessed something unusual in the sky, although many later considered an optical illusion or another ordinary explanation possible.

About 45% said they had believed in UFOs or aliens for as long as they could remember.

The wording illustrates the effect of threshold differences.

“Something unusual in the sky” captures many more experiences than the narrower “Have you seen a UFO?”

Experiential statistics consequently need exact wording before they can be compared across surveys.

2025 Cadem Survey in Chile

A Cadem survey of 700 respondents in Chile found approximately 78% believing extraterrestrial beings exist.

About 36% said they had witnessed a UFO at some point.

Respondents were also divided about the possibility of contact with extraterrestrial beings by 2030.

These percentages exceed many comparable United States and United Kingdom measurements.

The difference may involve national attitudes, question wording, sampling, media culture, institutional trust, religious context, or the strong cultural history of UFO reporting in parts of Latin America.

One survey cannot separate those explanations.

Cross-national comparisons become strongest when identical questions are fielded at approximately the same time using harmonized methodology.

The existing polling collection provides useful national snapshots but does not yet constitute a controlled international tracking program.

What the Statistics Show Over Time

The most useful way to interpret the chronology is to separate the measurements into several recurring categories.

Belief That Extraterrestrial Life Exists

Broad belief in life beyond Earth has become a majority position in most modern American surveys.

Gallup found approximately 75% in 2019 believing life of some form exists beyond Earth.

That percentage should be interpreted as a broad astrobiological measure because “life of some form” can include microorganisms.

More specific intelligent-life questions tend to produce somewhat lower results.

YouGov measured about 61% in 2021.

Pew measured approximately 65% during the same year.

Morning Consult recorded about 62% among registered voters in 2022.

YouGov measured 53% using “aliens” in March 2024 and 56% in November 2025.

CBS News/YouGov measured 63% believing intelligent life exists on other planets in June 2026.

The figures do not support a precise year-by-year curve because question wording differs.

They do support a broader conclusion: extraterrestrial intelligence has become a mainstream possibility for a majority or near-majority of Americans.

CBS’s longer historical comparisons provide stronger evidence of generational change. Fewer than half of respondents accepted intelligent extraterrestrial life in its 2010 polling, compared with 63% in 2026.

That is a more meaningful long-range change than fluctuations of several percentage points between modern surveys.

Belief That UFOs Have an Extraterrestrial Origin

Attributing UFOs to extraterrestrial technology produces lower percentages.

Gallup’s most comparable series rose from 33% in 2019 to 41% in 2021 among respondents saying some UFO sightings had been alien spacecraft.

YouGov found about 34% in 2022 identifying UFOs as likely alien ships or alien life.

A 2024 YouGov survey found about 29%.

November 2025 YouGov polling found approximately 30%.

These are not exact repeats of Gallup’s question, so the later percentages cannot establish a single continuous trend.

They suggest that extraterrestrial interpretation of UFOs commonly attracts somewhere around three in 10 to four in 10 respondents under many contemporary formulations.

The Gallup 2019-to-2021 movement remains the strongest evidence for a measured short-term increase because the same organization repeated the same core proposition.

Belief That Extraterrestrials Have Visited Earth

Visitation questions form another category.

Gallup measured approximately 27% in 1990, 33% in 2001, and 24% in 2005 believing extraterrestrial beings had visited Earth.

In November 2025, YouGov found approximately 47% saying aliens had definitely or probably visited Earth at some point.

The substantial difference suggests greater modern acceptance, but survey methods, wording, response scales, and cultural circumstances changed considerably over the intervening decades.

The 2025 poll also demonstrates that visitation belief can exceed direct UFO attribution.

About 47% accepted some past visitation, but only about 30% thought UFOs were probably alien ships or life forms.

A person can therefore believe extraterrestrials visited Earth at some unknown time without interpreting contemporary UFO reports as evidence of that visitation.

Belief That Contact Has Already Occurred

Confirmed-contact questions attract still smaller shares.

A 2017 YouGov measurement found only about 12% believing alien contact had occurred and government was concealing it.

CBS News/YouGov found about 21% in 2026 believing humanity had already made contact with intelligent extraterrestrial life.

These questions carry a heavier evidentiary claim than general visitation.

They require respondents to believe that some form of meaningful interaction has occurred rather than simply that an extraterrestrial object or being reached Earth.

Personal UFO Sightings

Self-reported sightings show substantial variation.

Gallup recorded about 5% reporting a flying-saucer sighting in 1966.

The percentage reached 16% in Gallup’s 2019 polling.

YouGov found about 19% in 2021 and 24% in 2022.

Ipsos measured approximately 10% in 2023.

Two YouGov-related surveys in 2024 produced approximately 18% and 20%.

YouGov found about 21% in 2025.

CBS News/YouGov measured 17% in 2026.

This sequence does not show a smooth modern increase.

A reasonable interpretation is that national estimates often fall somewhere from the mid-teens to low-20% range under survey wording that asks whether respondents have ever seen something they thought was a UFO, with some polls producing lower results.

The 1966 figure suggests a possible long-term increase in willingness to classify an experience this way, but terminology and cultural context have changed too much for a precise 60-year trend calculation.

Follow-up questions are highly informative.

In several YouGov surveys, substantial numbers of people who reported a UFO sighting still favored natural or terrestrial explanations.

The experience and its later interpretation are separate variables.

Government Secrecy and Disclosure

Government secrecy consistently produces some of the highest percentages.

Gallup found 71% in 1996 saying government knew more about UFOs than it disclosed.

Gallup found 68% in 2019 using the same broad concept.

YouGov found 56% in 2020 saying government would hide evidence if it had it.

About 65% in 2021 said government was not honest concerning UFOs.

Several 2023 and 2024 polls produced majorities believing public disclosure was incomplete.

An April 2025 registered-voter survey found 44% believing government was hiding information concerning the existence of UFOs.

A November 2025 YouGov poll found 73% saying government would hide UFO evidence if it possessed it.

CBS News/YouGov found 84% in June 2026 saying government knew more than it was telling the public.

These figures should remain in separate subseries because their wording differs.

The strongest historical comparison comes from Gallup itself: 71% in 1996 and 68% in 2019.

That pair indicates that distrust concerning UFO disclosure has been deeply established for decades.

The 84% CBS result demonstrates very high contemporary suspicion but cannot by itself establish that distrust rose by 16 percentage points from 2019 because CBS and Gallup did not use an identical instrument.

Expectations of Future Contact

Modern polling increasingly asks when humanity might contact extraterrestrial intelligence.

YouGov surveys show that respondents become more willing to anticipate contact as the horizon expands.

A 2024 survey found approximately 19% expecting contact within 10 years and about 31% within 50 years.

The proportion rose to roughly 42% over 100 to 200 years.

November 2025 YouGov polling found approximately 16% expecting contact within 10 years, 29% within 50 years, 42% within 100 years, and 46% within 200 years.

The year-to-year movements were small.

The stronger pattern lies in the time horizon itself. Long-term contact appears considerably more plausible to respondents than near-term contact.

Expert Belief in Extraterrestrial Life

Scientist surveys consistently need their own category.

The 2024 scientist study published in 2025 found approximately 87% of surveyed astrobiologists and 88% of scientists outside astrobiology considering basic extraterrestrial life likely.

Support declined when questions moved to complex and intelligent life.

A separate highly educated and science-engaged sample produced approximately 95% belief in extraterrestrial intelligent life.

These percentages describe populations with scientific backgrounds or unusually high engagement with science.

They should not be interpreted as estimates of the general public.

They also should not be interpreted as scientific endorsement of extraterrestrial explanations for UFOs.

The probability that life exists somewhere in the universe is a scientific question separate from the cause of reported UAP.

What Can Be Said With the Most Confidence

Several conclusions survive the differences in wording, samples, field dates, and survey organizations.

Belief in extraterrestrial life is substantially broader than belief in extraterrestrial visitation or direct contact.

Modern United States polling commonly finds a majority accepting intelligent life elsewhere. Questions that allow microbial or unspecified life can produce still higher percentages.

Belief that some UFOs represent extraterrestrial technology attracts a smaller but substantial minority.

Gallup documented an increase from 33% in 2019 to 41% in 2021 using a directly repeated question. Later YouGov results generally place extraterrestrial UFO interpretations near 30%, although the wording is different enough that the series cannot be extended directly.

Belief in government secrecy is both widespread and historically persistent.

Gallup found essentially the same high level in 1996 and 2019. Modern polls continue to find majorities expecting incomplete disclosure, and the June 2026 CBS News/YouGov poll produced an 84% response to a broad government-knowledge question.

Personal UFO sightings remain a minority experience in representative surveys.

Modern American estimates commonly fall somewhere around one in six to one in five respondents, although individual surveys range outside that band.

A sighting does not imply an extraterrestrial interpretation. Repeated follow-up questions show that many self-reported witnesses prefer natural, terrestrial, or uncertain explanations.

Public opinion concerning extraterrestrial life appears to have changed more clearly over the long term than government-secrecy attitudes have.

CBS historical data show intelligent-life belief moving from below half in 2010 to 63% in 2026.

Gallup’s secrecy measurements, by contrast, remained near seven in 10 between 1996 and 2019.

This creates an interesting divergence.

Americans appear increasingly comfortable with the scientific possibility of intelligent life elsewhere, but distrust concerning government UFO disclosure was already widespread before that shift.

The UAP era has also broadened the questions pollsters ask.

Older surveys often concentrated on flying saucers, visitation, or paranormal belief.

Modern surveys distinguish UAP sightings, military encounters, government investigations, alien existence, intelligent civilizations, contact timelines, whistleblower claims, congressional disclosure, personal experiences, and national-security implications.

That richer questionnaire design explains some of the apparent complexity in recent statistics.

It also shows why “What percentage of Americans believe in UFOs?” is not a sufficiently precise question.

Depending on what “believe” means, a defensible answer might refer to belief in extraterrestrial intelligence, belief in visitation, belief that some UFOs are alien spacecraft, belief that contact has occurred, personal sightings, or belief that government knows more than it says.

Those categories can differ by 40 percentage points or more within a single survey.

The June 2026 CBS News/YouGov poll provides the clearest contemporary example.

Approximately 63% believed intelligent life exists on other planets.

Only 21% believed contact had already occurred.

Approximately 17% reported personally seeing something they considered a UFO.

Yet 84% thought government possessed more information than it had disclosed publicly.

Those results describe four different attitudes held by overlapping groups of people.

Treating them as one “UFO belief” statistic would erase most of what the polling actually reveals.

Summary

More than six decades of polling show that public opinion concerning UFOs and extraterrestrial life has never been a single belief.

The strongest evidence points to several separate trends.

Acceptance of extraterrestrial life, including intelligent extraterrestrial life, is common and appears higher than in older polling. Contemporary American surveys frequently place intelligent-life belief between the mid-50% and mid-60% range, with broader questions concerning any extraterrestrial life producing still larger percentages.

Attribution of UFOs to extraterrestrial spacecraft attracts a smaller share. Gallup’s directly comparable measure increased from 33% in 2019 to 41% in 2021, providing one of the clearest short-term shifts in the historical record.

Belief that extraterrestrials have visited Earth can exceed direct UFO attribution. YouGov found 47% accepting probable or definite past visitation in November 2025, compared with about 30% interpreting UFOs as probable alien ships or life forms.

Confirmed-contact belief remains lower. CBS News/YouGov found only 21% in June 2026 believing humanity had already made contact with intelligent extraterrestrial life.

Personal UFO sightings generally involve a minority of respondents. Representative United States surveys since 2019 have frequently produced results from roughly the mid-teens to low-20% range, although survey-to-survey variation is substantial.

Government secrecy stands apart. Broad questions concerning undisclosed government UFO information have attracted large majorities for decades. Gallup recorded 71% in 1996 and 68% in 2019. CBS News/YouGov recorded 84% in 2026 under a broad government-knowledge question.

Those figures reveal a public-opinion structure that is more stable and internally differentiated than simplified believer-versus-skeptic narratives suggest.

Someone can believe intelligent extraterrestrial life probably exists and reject claims of visitation. Another person can believe government withholds UAP information yet think every unresolved case will eventually receive a terrestrial explanation. A person can report a UFO experience without believing an alien craft was involved. A scientist can regard extraterrestrial life as highly probable without accepting any extraterrestrial interpretation of UAP.

The long-term statistics consequently tell several stories rather than one.

Scientific openness to extraterrestrial life appears to have expanded.

Belief that at least some UFOs could represent alien technology increased measurably during at least one well-documented recent period.

Government secrecy expectations were already deeply established decades ago.

Personal-sighting percentages fluctuate rather than rise consistently.

Claims requiring increasingly specific assumptions, such as visitation, direct contact, or extraterrestrial interpretation of particular UFOs, generally attract progressively smaller portions of the population.

Future polling would become substantially more useful if major organizations repeatedly fielded a stable core of questions using identical wording: whether intelligent life exists elsewhere, whether any UFOs represent extraterrestrial technology, whether extraterrestrials have visited Earth, whether respondents have personally observed something they could not identify, whether government possesses undisclosed UAP information, and how confident respondents are in each answer.

Repeated standardized questions would make it possible to distinguish opinion change from differences produced by survey wording.

The accumulated record already establishes one broad result with considerable confidence: the possibility of extraterrestrial intelligence is no longer a fringe proposition in public opinion, but acceptance of that possibility remains very different from believing that extraterrestrials are responsible for reported UAP or that contact with humanity has already occurred.
