American Factbook

Every public number, kept current.

Data

Every dataset this site is built from, with the agency that publishes it, the terms it is published under, how often it changes, the date this copy was taken, and what the copy contains. Where we hold a cleaned table, it is downloadable here.

Each of these is a federal government work and is in the public domain under 17 U.S.C. § 105. The cleaning, normalization, and column naming are ours; take them and use them. We ask only that you cite the original agency rather than us, because the agency is the record and we are a copy of it.

What it cannot show

  • An encounter is an event, not a person. The same person may be encountered more than once in a period, so encounter counts are not a count of individuals.
  • Encounter counts describe enforcement activity. They do not measure migration, the number of people who crossed, or the size of any population.
  • Title 8 and Title 42 actions are different legal authorities with different consequences. Adding them together without saying so misrepresents both.
  • CBP republishes the file each month and revises earlier months in it. A figure is only as current as the snapshot it was drawn from.
  • "Area of Responsibility" is the CBP sector or field office that recorded the encounter, not the place a person entered or intended to go.

stg_fbi_cde_crime.csv.gz — gzipped CSV, 4.0 MB

What it cannot show

  • Reporting to the FBI is voluntary. Coverage varies by agency and by year, so a change in a state total can be a change in which agencies reported rather than a change in offenses.
  • Counts are offenses reported to law enforcement. They are not convictions and do not measure offenses that were never reported.
  • Rates use the FBI's own population denominators, which this pipeline stores alongside the counts so a published rate can be recomputed exactly as the FBI computed it.
  • The UCR programme moved from summary reporting to NIBRS, and agencies transitioned in different years. A change in a state's total can be a change in who reported, which is why agency participation is stored with the crime figures.
  • Agencies revise submissions. A figure is only as current as the snapshot it was drawn from.

stg_usaspending_spending.csv.gz — gzipped CSV, 71 KB

What it cannot show

  • USAspending reports obligations and outlays as agencies submitted them. It is not an audited financial statement and does not reconcile to one.
  • Award records are revised after publication. A figure is only as current as the snapshot it was drawn from.
  • Place of performance is the location the recipient reported, not necessarily where work was carried out.
  • An award amount is the value of the award, not money spent. Obligations and outlays are different measures and are not interchangeable.
  • Insurance figures are face value, like a loan guarantee, not money paid. The publisher's reporting of them changes sharply after FY2013, which is a change in reporting and not in spending.
  • The history starts at FY2008. The API states its own floor on every search response: "time period start and end dates are currently limited to an earliest date of 2007-10-01". Federal spending did not start there; our record of it does.
  • The open fiscal year is incomplete. It is not comparable to a closed year, and a fall against last year may only mean the year is not over.
  • The agency-by-state matrix covers the current fiscal year only. Agency totals and state totals cover every year.
  • An agency's slug is derived by USAspending from its name. An agency that is renamed gets a new slug, and its history appears under two identities rather than one.

Named but not yet held

These sources are part of a hub’s plan and have no copy here yet. They appear on the hub that will use them, and they will appear in the register above on the day they are first fetched.

How to cite

Cite the agency and the date of the copy you used, not this site. A figure taken from here on 2026-09-19 is a figure from the agency’s file as it stood on that date, and agencies revise their files. If you want the version we used rather than the version live today, the download above is that version.

How these tables are produced, and what we do and do not change in them, is on the methodology page. Errors we have found and fixed are logged on corrections. If you find one, tell us.
