IMPACT SUMMARY
Eight UFO Statistics You Can Quote With Their Limits Intact
Each answer below includes its period, denominator, source and the caveat most likely to be lost when the number is repeated. The copy control preserves all four.
How many UAP reports were in AARO's holdings?
As of 30 May 2025, AARO's case holdings contained 1,870 UAP reports.
Caveat A report is an intake record, not a verified anomalous object or a unique craft. AARO can merge reports that describe one incident.
How many UAP reports did AARO receive in its FY2025 reporting period?
AARO received 319 UAP reports covering 2 June 2024 to 30 May 2025, including 35 reports about earlier events.
Caveat The reporting period is not calendar year 2025. Of the 319 reports, 284 concerned events during the period and 35 concerned events from 2010 to 2024.
How many incoming FY2025 reports did AARO resolve?
AARO resolved 114 of the 319 incoming reports, or 35.7%, as prosaic objects or events.
Caveat Resolved means attributed to a prosaic category such as balloons, satellites, birds, aircraft, UAS, a rocket launch or a jet pack.
How many incoming FY2025 reports lacked enough data for assessment?
AARO transferred 191 of the 319 incoming reports, or 59.9%, to its active archive pending corroborating data.
Caveat Active archive means insufficient data for a comprehensive assessment. It does not mean AARO found an extraordinary origin.
What explains most of AARO's closed cases?
Balloon and satellite identifications account for 772 of 907 closed cases on AARO's dashboard, or 85.1%.
Caveat This denominator contains closed cases only. It cannot be applied to all reports in AARO's holdings.
Which morphologies appear most often in AARO's published trend data?
Orb, round or sphere reports plus lights account for 431 of 599 reports with published morphology, or 72.0%.
Caveat Not all reports contain morphology data. The calculated combined share is 72.0%; AARO's separately rounded category percentages sum to 71.9%.
How many UFO reports does NUFORC list for 2025?
NUFORC's live Reports by Month index listed 4,578 reports with sighting dates in calendar year 2025 when checked on 21 August 2026.
Caveat This is a live civilian reporting index organised by reported sighting month, not submission date or confirmed-event count. Late reports can revise earlier months.
How many UFO reports does NUFORC list for 2026 so far?
NUFORC's live Reports by Month index listed 1,886 reports with sighting dates from January through 21 August 2026.
Caveat August 2026 is a partial month. The index is live, groups reports by reported sighting month rather than submission date, and can change as late reports are processed.
OFFICIAL INTAKE
How Many UAP Reports Are Recorded Officially?
AARO's latest consolidated report says its holdings contained 1,870 reports as of 30 May 2025. That is the clearest current U.S. government holdings total. It is not a worldwide count, a calendar-year count, or the number of objects that investigators judged anomalous.
The same report covers an incoming set of 319 reports received for the period from 2 June 2024 to 30 May 2025. Of those, 284 described events during that period and 35 described earlier events from 2010 to 2024. A late report and a newly occurring event therefore sit in the same incoming total even though their event dates differ.
Why 1,870 And 319 Answer Different Questions
The 1,870 figure describes AARO's cumulative case holdings at a point in time. The 319 figure describes reports entering the latest annual-report workflow. A person asking “how many UFO reports were there in 2025?” could mean reports received, events that occurred, reports published publicly, civilian sightings, military reports or all records held by an office. None of those units is automatically equivalent.
AARO also states that it may merge two or more reports when they correspond to one event. It performed two merger actions during the FY2025 reporting period. That is one reason report totals should not be restated as unique events, vehicles or witnesses. One event can produce several reports, while one report can describe several apparent objects.
Who Can Report To AARO?
AARO is not a general-purpose worldwide public reporting centre. Military and Department of War civilian personnel report through official channels. Civilian pilots are encouraged to report relevant observations to air traffic control, and AARO receives UAP-related pilot reports from the Federal Aviation Administration. Its secure public-facing mechanism is designed for eligible current or former U.S. government personnel, service members and contractors reporting first-hand knowledge of government UAP programmes or activities.
That scope shapes the database. The FY2025 report says higher densities of U.S. military sensors and assets tend to produce more reports, creating a collection bias towards the continental United States, nearby waters and U.S. operational areas. AARO's holdings are therefore an institutional record of what reaches those channels, not a census of unusual things in the global sky.
What Changed In The Latest Annual Report?
The FY2025 annual report was added to AARO's public congressional-products page on 20 July 2026. It is the newest official annual snapshot used here. It reports 274 incoming cases in the air domain, 44 in the space domain and one in the maritime domain. The space-domain reports did not originate from space-based sensors: 42 came from civilian pilot reports passed through the FAA and two came from ground-based U.S. Space Command sensors.
That distinction is a useful check on dramatic wording. A “space-domain” case does not necessarily mean an instrument in space detected an unknown spacecraft. It can describe a ground or airborne observer reporting an apparent phenomenon above the Kármán line. AARO says it resolved those 44 reports as satellite flaring after applying all-source analysis and three-dimensional modelling.
The official intake numbers are valuable because they show workload, reporting channels and where analysis stalls. They do not establish the physical nature of every underlying observation. For current institutional context, see the Otherworlders guide to the AARO UAP office.
CIVILIAN REPORTING
How Many UFO Reports Did NUFORC Record In 2025 And 2026?
When checked on 21 August 2026, the National UFO Reporting Center's live Reports by Month index contained 4,578 reports with sighting dates in 2025. For 2026 so far, it contained 1,886 reports dated from January through 21 August. The 2026 figure includes 116 reports assigned to August, so it is a partial-year total with a partial final month.
Those are civilian reporting counts, not AARO case totals. NUFORC accepts reports from the public and publishes an independently collected database. AARO receives information through U.S. defence, intelligence and aviation channels. A report can reach one system and not the other, and the organisations use different review, classification and publication processes.
Monthly Counts For 2025 And 2026 So Far
January was the largest 2025 sighting month in the current NUFORC index, with 587 reports. The full 2025 monthly series averaged 381 reports per month. From January through July 2026, the index contained 1,770 reports, compared with 2,761 for the same seven months of 2025—a difference of 991 reports, or 35.9% fewer.
That year-over-year comparison stops at July because August 2026 was incomplete on the check date. It describes the index as published, not a measured change in how often unexplained objects appeared. Reporting volume can move with public attention, internet access, moderation, processing delays, weather, sky visibility and prominent events such as satellite launches.

NUFORC's index is live and organised by reported sighting month. August 2026 is partial, and historical months can change when later submissions are processed. Counts describe self-reported records, not verified objects or unique events. Source: NUFORC Reports by Month. Reuse terms.
Why NUFORC's Year Total Can Change Later
The index is headed “Sighting Year/Month,” so these rows group records by when the observation was reported to have occurred. They are not counts of forms submitted or records posted during the same month. Someone can submit an older sighting today, and NUFORC can process or update a record later. A total for 2025 can therefore change during 2026.
NUFORC also states that most reports are published as received and that it makes no claim about the validity of the information in each report. The numbers measure records in a reporting system. They do not establish that every account describes a distinct event, a physical object or an unexplained craft.
How This Page Uses NUFORC Data
Otherworlders transcribed the small, published month-level aggregate needed to answer the annual-count question and links directly to the source. It does not copy individual narratives, mirror the database or distribute a reconstructed NUFORC dataset. The downloadable Otherworlders files contain only the published month and state aggregates used on this page, alongside source, checked-date and caveat fields.
That boundary respects NUFORC's reuse terms while making the quoted totals reproducible. For the freshest count, check NUFORC's live Reports by Month index; for citation, preserve the checked date because the table can move.
REPORTED LOCATIONS
Where Are The Most UFO Sightings Reported In The United States?
In NUFORC's live cumulative location index, California had the most U.S. reports with 17,262 when checked on 21 August 2026. Florida ranked second with 8,938, Washington third with 7,666, Texas fourth with 6,759 and New York fifth with 6,381.
The careful answer is that California has the most records in this reporting index. These are raw cumulative reports, not confirmed sightings and not a rate adjusted for population, land area, years of coverage or time spent looking at the sky. A populous state can accumulate more reports simply because it has more potential observers.
The Ten States With The Most Reports In NUFORC's Index
The ranking below uses NUFORC's published state-level aggregate, not a harvested copy of its individual database. It answers a useful location question while retaining the reporting-system denominator and the date on which the live table was checked.

Raw cumulative reports, not rates. State population, observation opportunity, reporting awareness, internet access, historical coverage and processing can all affect the ranking. Counts do not represent verified objects or unique events. Source: NUFORC Reports by Location. Reuse terms.
Why This Is Not A Ranking Of “UFO Activity”
Population is only one source of bias. Weather, cloud cover, light pollution, outdoor activity, aviation traffic, internet access, awareness of NUFORC and willingness to submit a report can all change the number recorded for a state. Historical differences in database coverage and report processing can also shape a cumulative ranking.
The table is not annual, so it cannot show which state led in 2025 or 2026 without a separate permitted year-and-state aggregate. It also cannot show how many reports were independently corroborated. Those questions require different denominators and should not be inferred from the cumulative totals.
For the latest state totals, use NUFORC's live Reports by Location index. NUFORC states that it makes no claim about the validity of the information submitted, so every location figure on this page is labelled as a report count rather than a count of verified objects or events.
CASE DISPOSITION
How Many UAP Reports Are Resolved, Open Or Missing Data?
Of the 319 reports in AARO's FY2025 incoming set, 114 were resolved, 191 entered the active archive, nine merited further analysis by intelligence-community or science-and-technology partners, and three were recommended for closure pending review and director authorisation. AARO also recorded two case-merger actions during the period, so those workflow statements should be cited as published rather than forced into a homemade four-part pie chart.
Resolved Does Not Mean “Debunked Witness”
A resolution attributes the reported observation to a prosaic object or event with sufficient confidence for the office's process. AARO says the 114 resolved incoming cases involved balloons, birds, satellites, aircraft, unmanned aerial systems, one rocket launch and one manned jet pack. The category describes the assessed cause of the observation. It does not tell us that every witness was careless or that every report was worthless.
Ordinary explanations can require substantial analysis. Satellite flares are a strong example. A moving point of reflected sunlight may appear bright, stationary or unexpectedly mobile from a particular viewing geometry. The latest annual report says a new modelling capability helped analysts resolve 238 reports from the broader caseload as satellite flaring. Forty-four of those resolutions concerned reports received during the FY2025 period.
Active Archive Is A Data Status
AARO defines its active archive as a repository for cases lacking enough data for comprehensive analysis. The 191 incoming cases moved there can be reopened if new corroborating data or improved techniques become available. The category does not assert that an event displayed impossible performance, and it does not positively identify a mundane cause.
This is the central interpretive trap in UFO statistics. “Not resolved” and “evidence of an extraordinary craft” are not equivalent statements. A blurry image without timing, sensor details or a calibrated field of view may remain unresolved because the evidence is weak. A genuinely unusual observation can also remain open. The status alone does not separate those possibilities.
Closed-Case Explanations Across AARO's Dashboard
AARO's live reporting-trends dashboard uses another denominator: 907 closed cases covering reports dated from 1 January 1996 to 15 June 2026. Balloon identifications account for 460 closed cases and satellite identifications for 312. Together they represent 772 of 907, or 85.1%, of the closed-case table.
That 85.1% share must stay attached to closed cases. It cannot be applied to the 1,870 total holdings or used to claim that exactly 85.1% of all UAP reports are balloons or satellites. Cases that can be resolved may differ systematically from cases that remain open or lack data.

Why The Dashboard And Annual Report Move At Different Speeds
The annual report is a bounded congressional product with an information cut-off. The live dashboard is a later, rolling publication. Its closed-case total can include older cases resolved after their original intake period, and its date range extends beyond the annual report's 30 May 2025 cut-off. Comparing the two can reveal process, but subtracting one from the other does not produce a reliable count of currently open cases.
The same rule applies when an official page changes. A figure quoted from a 2024 annual report remains a valid historical snapshot, but it should not silently replace or merge with a 2026 dashboard figure. This page stores the period and checked date alongside each value so updates remain auditable.
REPORTED CHARACTERISTICS
Which UFO Shapes And Altitude Bands Are Reported?
In AARO's public trend table through 15 June 2026, orb, round or sphere is the largest morphology category at 226 of 599 reports with morphology data, or 37.7%. Lights follow at 205 of 599, or 34.2%. Combined, those categories contain 431 of 599 morphology-coded reports.
The denominator is essential. AARO warns that not all reports include morphology. These figures describe the subset for which a shape or visual form reached the public table. They do not show that 37.7% of every report in AARO's holdings involved a sphere.
Shape Labels Describe Appearances, Not Vehicle Types
“Orb” can describe a compact light, a distant round object, an optical point source or an object whose detail was below the resolving power of a camera or observer. “Lights” is even broader. A morphology label preserves the reported appearance; it does not establish material structure, propulsion or origin.
The FY2025 annual report reports a similar broad pattern for its own period: among incidents with a distinct visual description, spheroidal objects represented 40% and lights 33%. It also says 77 of the 319 incoming reports lacked enough information to reach a morphology conclusion. That annual subset is not identical to the 599-record live-dashboard subset, so the percentages should not be pooled.
Altitude Reporting Peaks In Aviation Bands
AARO's live table contains 1,231 reports with an altitude band. The largest category is 20,000 feet, with 287 reports or 23.3%. The 25,000-foot band contains 203 reports or 16.5%. Together those bands account for 490 of the 1,231 altitude-coded reports, or 39.8%.
The FY2025 annual report describes airborne reports as predominantly between 10,000 and 35,000 feet. That concentration is consistent with the reporting system's aviation inputs, including military operations and civilian pilot reports. It should not be read as a physical “preferred altitude” for unknown craft without adjusting for where observers and sensors operate.
Reported altitude can also be an estimate rather than an instrumented measurement. A point of light with unknown size and distance does not provide a reliable altitude by appearance alone. Radar, range data, calibrated imagery and known observer geometry can improve an estimate; a narrative report may not contain any of them.

Altitude values are reported bands and may be estimates. AARO's visual uses an Above 60K category and marks the Kármán line as the upper reference.

Why High-Altitude Counts Can Change After Better Identification
The FY2025 report says the share of reports above 45,000 feet fell from 27% in the previous annual report to 4%. AARO attributes much of the change to the earlier intake of high-altitude FAA reports and to improved identification of satellite flaring. This is a good example of an analytical trend changing because collection and resolution changed, not necessarily because the sky changed.
Morphology and altitude are most useful when joined to time, location, viewing geometry, sensor type, calibration, weather and known traffic. Without that context, a shape-frequency chart is a record of descriptions rather than a taxonomy of physical objects.
HISTORICAL BASELINE
How Do Modern UAP Statistics Compare With Project Blue Book?
The U.S. Air Force programmes grouped in the Project Blue Book record received 12,618 sightings from 1947 to 1969. The National Archives says 701 remained labelled “Unidentified”, equal to 5.6% of the total. Those numbers are historically important, but they are not an apples-to-apples benchmark for AARO.
Blue Book operated across a different period, legal setting, sensor environment and reporting culture. Its total covers more than two decades. AARO's 319 figure covers one annual-report intake period, while its 1,870 figure describes cumulative holdings as of a date. Comparing 701 with 191, for example, would compare Blue Book's final unidentified classification with AARO's active archive of reports lacking enough data.
| Dimension | Project Blue Book Record | AARO Record |
|---|---|---|
| Headline count | 12,618 sightings reported from 1947 to 1969. | 1,870 reports in holdings as of 30 May 2025. |
| Published unresolved-style figure | 701 labelled unidentified at programme close. | 191 of 319 latest incoming reports transferred to active archive for insufficient data. |
| Time basis | Programme-era cumulative total. | Point-in-time holdings, annual intake and rolling dashboard all published separately. |
| Collection environment | Cold War Air Force investigation, witness reports, film, radar and contemporary military channels. | Multi-domain defence and intelligence process with FAA inputs, modern imagery and modelling. |
| Safe conclusion | Both programmes accumulated unresolved records, but neither unresolved share is a measured rate of extraterrestrial craft. | |
Blue Book's 701 Cases Are A Classification Remainder
The 701 figure means the Air Force did not assign those cases a satisfactory identification within its system. It does not mean investigators proved that 701 extraterrestrial vehicles entered U.S. airspace. The Air Force's published position was that it found no evidence that unidentified cases represented technological developments beyond contemporary scientific knowledge or extraterrestrial vehicles.
That official conclusion is part of the source record, not the last word on every disputed case. Historians and UFO researchers have criticised case handling, evidentiary standards and institutional incentives. A statistics page should preserve that debate without changing the meaning of the programme total.
What A Historical Comparison Can Show
Both eras demonstrate that an investigation system creates several kinds of remainder. Some reports are identified. Some lack enough information. Some remain disputed despite an official explanation. Some retain unusual details after review. Treating all of those categories as one “unexplained” bucket hides the quality of the evidence and the reason a file stayed open.
The modern advantage is not merely better sensors. It is the possibility of better provenance: calibrated instruments, precise timestamps, metadata, common reporting fields and models that can test satellite or aircraft geometry. The historical disadvantage is that older files often preserve only narrative summaries, copied photographs or partial radar accounts. Explore the programme history in the Project Blue Book guide.
OWNED DATASET
What Does The 184-Record Otherworlders Archive Contain?
The Otherworlders map snapshot contains 184 source-linked records: 78 official records, 83 documented case files, 17 historical reports and six community reports. These numbers describe the composition of a curated editorial archive. They are not representative estimates of where UFOs occur or which evidence type is most common worldwide.
The archive was designed for source navigation. A record can be an individual case, an official video entry, a historical report, a government archive route or a release hub. That breadth is useful for discovery but makes a raw row count unsuitable as a sightings incidence rate.

How Evidence Modes Are Counted
Evidence is multi-select. A single case can contain pilot testimony, radar context, photographs and an official document trail. Counting that record in four relevant categories preserves more information than forcing it into one “strongest evidence” box. It also means evidence percentages overlap and may total more than 100%.
The tags describe the contents of the source package. “Photo or video” means the archive record links to or discusses image material; it does not certify that the image depicts an anomalous craft. “Official document” means a government source or file trail is present; it does not mean the government endorsed an extraordinary interpretation. “Physical trace or effect” records a reported trace, injury or interference claim, not independent proof that the claimed cause produced it.

Which Eras Appear In The Archive?
The timeline contains 178 event-dated records. Six records that function as catalogue pages, studies, trend dashboards or release hubs are excluded because their page date is not an observation date suitable for an event timeline. The remaining chart still measures editorial coverage, not historical event frequency.
Contemporary and Blue Book-era records dominate because those periods offer more public documentation, official imagery and developed case literature. Ancient, medieval and early-modern entries are intentionally separated as historical sky reports with lower-confidence source and location handling. Their inclusion helps readers trace how unusual-sky narratives change across source types; it does not recast chronicles as modern instrumented sightings.

Geography And Shape In The Archive
North America is overrepresented because Otherworlders has deep coverage of U.S. government programmes, classic American cases and AARO's public products. Multi-region records include broad operational theatres, international waters and source groups that cannot be assigned to one country without inventing precision. Map coordinates can mark an approximate case area, reporting office or archive location, depending on the record.
Shape analysis uses a stricter denominator than the 184-record archive total. Archive pages, document records, aggregate dashboards and generic sensor-file entries without an observed form are explicitly excluded. That prevents a PDF release or thermal-file index from becoming an “object shape” merely because it occupies a map row.

| Entity Or Occupant | 7 | 5.8% |
| Triangle Or Boomerang | 5 | 4.1% |
Shape denominator: 121. 63 archive, document, aggregate or sensor-file records without an observed morphology are excluded.
Resolution Classes Are Editorial Controls, Not Verdicts
Every record also receives a controlled resolution class: resolved, unresolved, insufficient data, contested or open, historical report, unverified, or reference record. The sidecar does not overwrite the source's wording. It creates consistent aggregate groups while keeping the original map status available for case-level reading.
A historical chronicle is not forced into a modern resolved/unresolved binary. A community submission remains unverified. An official release hub remains a reference record rather than an incident. These distinctions reduce the temptation to make one dramatic “percentage unexplained” from records that were never collected under one investigative protocol.
INTERPRETATION LIMITS
Why UFO Reporting Data Cannot Establish Extraterrestrial Origin Or True Occurrence Rates
Report databases measure reporting. They do not directly measure how often unusual physical events occur, how many objects exist, or what caused every observation. The path from an event to a database row passes through visibility, human attention, willingness to report, access to a reporting channel, institutional screening and data publication.
Selection Bias Begins Before A Report Is Filed
People look at the sky unevenly. Pilots, military personnel, astronomers and residents under clear dark skies have different exposure to aerial phenomena. City lighting, cloud, terrain, tree cover and time outdoors affect what can be seen. Public attention can also change reporting behaviour after news events, government hearings, film releases or widely shared satellite launches.
AARO's own report identifies a collection bias towards places with U.S. military sensors and assets. A civilian database has another set of biases: internet access, public awareness, moderation rules and the demographics of people willing to submit a report. A map hotspot may therefore indicate reporting opportunity as much as event opportunity.
Missing Data Is Not A Physical Characteristic
A case can remain unresolved because it lacks a precise time, raw image, sensor metadata, known camera settings, angular measurements or corroborating observations. That absence belongs to the record, not necessarily to the phenomenon. Counting data-poor cases as evidence of advanced technology turns an investigative limitation into a physical claim.
NASA's UAP independent study places calibration and metadata at the centre of scientific progress. Sensor type, manufacturer details, noise characteristics, acquisition time and observing mode help analysts distinguish an apparent object from an artefact and reconstruct what an instrument could have measured. A striking clip without those details may be less analytically useful than an ordinary-looking observation with complete metadata.
Reports, Witnesses, Events And Objects Can Multiply Differently
One bright satellite flare can generate reports from several observers. One observer can describe a formation of many lights. Several agencies can hold copies of the same event. A later release can add an imagery record and a case-resolution record for material already represented elsewhere. Without entity resolution, counting rows as unique craft inflates the result.
The Otherworlders archive makes this visible by labelling record types and excluding non-event references where appropriate. It does not claim to have deduplicated every historical report into a definitive global incident register.
Classification Depends On Available Methods
An unresolved share can fall when analysts gain better satellite ephemerides, atmospheric models or sensor reconstructions. It can rise when a new reporting channel receives many incomplete narratives. Neither movement alone shows that anomalous activity increased or decreased.
The FY2025 shift in high-altitude reports illustrates the point. AARO linked the change to an earlier batch of FAA reports and improved satellite-flare identification. The data-generating process and the analytical process both moved.
No Published Aggregate Here Proves Extraterrestrial Activity
AARO states that the cases it resolved did not indicate advanced foreign capabilities or breakthrough technologies. It also says that, to date, no evidence suggests a U.S. government or private entity captured or exploited UAP-derived materials. Those are institutional findings within AARO's remit and evidence access.
They do not logically prove that extraterrestrial life does not exist. They show that these report holdings and published analyses have not established extraterrestrial technology. The existence of unresolved files likewise does not prove that extraterrestrial technology is present. Both claims would require affirmative evidence beyond a residual category.
Public Reporting Research Measures Human And Environmental Patterns
A 2023 Scientific Reports study analysed 122,983 U.S. reports submitted to the National UFO Reporting Center and dated from June 1930 to June 2022. The researchers focused on how population and “sky view potential” related to reported sightings. They noted that internet access likely contributed to growth in reports over time.
That is a legitimate use of a reporting dataset: test relationships between recorded reports, environment and reporting opportunity. It is not a count of confirmed anomalous vehicles. Otherworlders cites the published aggregate and findings but does not scrape, mirror or reproduce NUFORC's database. NUFORC's terms prohibit harvesting without express consent.
METHOD // V1.0
Methodology, Data Layers And Refresh Process
This hub uses three separate data layers so official claims, editorial classifications and generated outputs can be checked independently. The normal site build performs no external fetch. A deliberate refresh command regenerates the aggregate downloads and marked HTML sections after a human reviews changed sources.
Layer One: Manually Reviewed Statistics Ledger
Each official, academic or published-aggregate metric has a stable ID, a question, a complete answer, value, unit, numerator, denominator, period, scope, source name, source URL, checked date and caveat. A dashboard figure is stored with the dashboard coverage date. An annual-report figure is stored with its reporting period and information cut-off. A live civilian index also keeps its check date and partial-month status. These sources are never silently combined.
Chart category counts are transcribed into the same reviewed ledger. Validation confirms that category counts reconcile with the declared denominator and that published percentages match the count calculation within rounding tolerance.
Layer Two: Record-Level Classification Sidecar
Every map record ID has a tracked sidecar entry with controlled source class, resolution class, shape family, evidence tags, era, world region and eligibility flags. The build fails if a map ID is missing, duplicated or assigned an uncontrolled value. It also fails if a generic archive, document, aggregate or sensor-file record is made eligible for morphology analysis.
Evidence tags are arrays rather than single values. Shape and timeline exclusions include a written reason. The map data hash recorded at classification time ensures a changed snapshot cannot pass with an old sidecar.
Layer Three: Generated Aggregate Files
The public JSON includes official metrics, NUFORC month and U.S. location aggregates, chart data, archive aggregates, methodology notes, source hashes, source ledger and changelog. The CSV flattens the headline metrics, NUFORC month and state rows, and archive breakdowns into journalist-friendly rows. Both files are generated from the first two layers, and the build compares them byte-for-byte with a fresh deterministic calculation.
DATA DISTRIBUTION
Download The Reproducible Aggregate
Coverage: NUFORC monthly and U.S. location reports checked 21 August 2026, AARO holdings through 30 May 2025, AARO trends through 15 June 2026, Project Blue Book from 1947 to 1969, and the Otherworlders archive snapshot updated 2 August 2026.
Refresh And Freshness Rules
The intentional refresh command is npm run update:ufo-statistics. It validates the ledgers, recalculates the aggregates, writes the JSON and CSV distributions, and replaces only marked sections in this article. The normal build runs a check mode. If the map hash, source ledger, sidecar, downloads or marked HTML differ, the build stops with a stale-snapshot error.
A quarterly review is scheduled, with an earlier update whenever AARO, NUFORC or another primary source publishes a material change. A refresh also updates the visible last-verified date, changelog, human reviewer record, dateModified, downloads and metadata. The evergreen URL remains unchanged when the title year advances.

Calculation And Rounding Policy
Calculated shares use numerator divided by denominator, multiplied by 100 and rounded to one decimal place. Source-published percentages are retained in official chart rows after reconciliation. When two rounded source categories are added, the combined share is recalculated from counts rather than adding the displayed percentages.
For example, AARO publishes 226 orb, round or sphere reports and 205 lights reports in a 599-report morphology table. The combined calculation is 431 divided by 599, or 72.0% after rounding. AARO's separately rounded category labels, 37.7% and 34.2%, add to 71.9%. Both presentations can be correct within their stated rounding method.

QUICK ANSWERS
UFO Statistics FAQ
How Many UFO Sightings Are Reported Each Year?
There is no complete worldwide annual count. NUFORC's civilian index listed 4,578 reports dated in 2025, while AARO received 319 reports in its latest published period, 2 June 2024 to 30 May 2025. Those figures cover different populations, date bases and reporting systems and should not be added together.
How Many UFO Reports Did NUFORC Record In 2025?
NUFORC's live Reports by Month index listed 4,578 reports across the twelve 2025 sighting months when checked on 21 August 2026. This is an occurrence-month aggregate, not the number submitted during 2025, and late reports can revise it.
How Many UFO Reports Has NUFORC Recorded In 2026 So Far?
The live index listed 1,886 reports dated from January through 21 August 2026. August was incomplete, and the total can change as NUFORC processes later or backdated reports.
Which U.S. State Has The Most UFO Reports?
California led NUFORC's cumulative state index with 17,262 reports when checked on 21 August 2026. Florida followed with 8,938 and Washington with 7,666. These are raw reports rather than verified events or population-adjusted rates, so the ranking does not establish where UFOs physically occur most often.
How Many UAP Reports Does AARO Have?
AARO reported holdings of 1,870 cases as of 30 May 2025. The figure is a point-in-time case-holdings count. It should not be restated as 1,870 confirmed objects or events.
What Percentage Of UAP Reports Are Unresolved?
No single percentage applies to every AARO holding. In its FY2025 incoming set, AARO moved 191 of 319 reports, or 59.9%, to the active archive for insufficient data. Nine merited further partner analysis. Those statuses mean different things and should not be merged into an “extraordinary” category.
What Is The Most Common Reported UFO Shape?
In AARO's public trend table through 15 June 2026, orb, round or sphere is the largest category at 226 of 599 morphology-coded reports, or 37.7%. Lights are close behind at 205 reports, or 34.2%. Reports without morphology are outside that denominator.
At What Altitude Are UAP Most Often Reported?
The largest band in AARO's public altitude table is 20,000 feet, containing 287 of 1,231 altitude-coded reports. The 25,000-foot band is second with 203. Collection through aviation channels and the difficulty of estimating distance can influence the distribution.
How Many Project Blue Book Cases Were Unidentified?
The National Archives says 701 of 12,618 reported sightings remained labelled unidentified when the programme closed, equal to 5.6%. That historical classification is not directly comparable with AARO's active archive.
Do Unresolved UFO Reports Prove Aliens?
No. An unresolved report can lack enough information for identification. Establishing extraterrestrial origin would require affirmative, independently testable evidence that excludes terrestrial, astronomical, atmospheric, technological and sensor explanations.
Can I Reuse The Downloaded Data?
The aggregate JSON and CSV are designed for citation and analysis with attribution to Otherworlders and the named upstream sources. They do not contain a harvested copy of NUFORC's database. Follow each primary source's terms when using source material beyond the aggregate facts presented here.
CHANGELOG
Verification And Update Record
Completed editorial review under B48, set the final publication date and title, rechecked the NUFORC monthly figures, and added its published U.S. state aggregate led by California with 17,262 reports. Location totals are presented as raw cumulative reports, not per-capita or verified-event rates.
Added NUFORC's published monthly aggregates: 4,578 reports by 2025 sighting month and 1,886 through 20 August 2026, with a month-by-month comparison and live-index, occurrence-date and partial-month caveats. No individual NUFORC reports were harvested or redistributed.
Initial snapshot prepared from the AARO FY2025 annual report, AARO trend tables through 15 June 2026, National Archives Project Blue Book totals and the 184-record Otherworlders archive. Named human review remains required before publication.
