The World Factbook
The first classified edition of The World Factbook appeared in August 1962. It served U.S. government officials with almanac-style data on global countries. An unclassified version followed in June 1971, making the information available to a broader audience. The public could access printed copies starting in 1975 through the Government Publishing Office. Before November 2001, the website updated its content once per year. From 2004 to 2010, updates occurred every two weeks. Since 2010, the site has been refreshed weekly. Information current as of January 1 is typically used for each new edition. In 2008, the CIA stopped printing physical books and shifted focus to the online version. The official print run ended completely in 2017. The website launched in October 1994 and received about six million visits monthly by 2006. Earlier formats included CD-ROMs, microfiche, magnetic tape, and floppy disks.
The Central Intelligence Agency compiles entries using multiple government departments. The National Science Foundation provides Antarctic Information Program data. The Department of Defense contributes from the Armed Forces Medical Intelligence Center and the Defense Intelligence Agency. The Bureau of the Census under the Department of Commerce supplies demographic figures. Labor statistics come from the Bureau of Labor Statistics within the Department of Labor. Energy data originates from the Department of Energy. The Department of State offers diplomatic and political context. The Fish and Wildlife Service handles environmental details. Transportation information comes from the Maritime Administration and the United States Transportation Command. Geographic names are verified by the United States Board on Geographic Names. The Office of Insular Affairs manages territorial data for dependencies. Private sources like the Oil & Gas Journal supplement these government inputs. This interagency collaboration ensures a wide range of factual coverage across 258 international entities. The style and format prioritize meeting U.S. government requirements above all else.
October 1994 marked the moment The World Factbook became available via the World Wide Web. Jill Young Miller reported this shift in the Fort Lauderdale Sun-Sentinel on the 12th of December 1994. By 2006, the site attracted six million visits each month. Before that time, physical media dominated distribution. CD-ROMs, microfiche, magnetic tape, and floppy disks were common formats. In 2008, the CIA decided to focus resources exclusively on the online edition. The Government Printing Office took over printing duties after that decision. Printed books officially ceased production in 2017. Publishers like Grand River Books, Potomac Books, and Skyhorse Publishing have released reprints since then. Older editions from 2000 onward can be downloaded but not browsed directly on the main site. The website remains in the public domain within the United States. Users may redistribute content without permission though citation is requested by the agency. Copying the official CIA seal remains prohibited under the Central Intelligence Agency Act of 1949.
The Chagos Archipelago entry lists the area as British Indian Ocean Territory rather than Mauritian land. This reflects U.S. policy which does not recognize Mauritius sovereignty over the islands. A UN General Assembly resolution dated the 24th of May 2019 called for UK withdrawal from colonial administration there. One hundred sixteen countries including Seychelles voted in favor while only six including the US opposed it. The Factbook erroneously claims the archipelago is also claimed by Seychelles despite this vote. Kashmir appears with the Line of Control border drawn between India and Pakistan. China-administered regions show hash marks instead of solid lines. Northern Cyprus lacks a separate entry because U.S. maps do not show territories occupied or annexed without recognition. Taiwan's government section lists no official name due to Beijing's One-China policy. An attempt to add Republic of China briefly occurred on the 27th of January 2005 before reverting to none status. Burma retains its old name even after the ruling junta changed it to Myanmar. North Macedonia was listed as Former Yugoslav Republic of Macedonia until the 19th of February 2019 when the name updated again. Kosovo received an entry starting the 28th of February 2008 following its declaration of independence earlier that month.
In June 2009, National Public Radio used Factbook data stating 250,000 Israeli Jews lived in West Bank settlements. State Department and Israeli sources later estimated the number closer to 500,000. NPR issued a correction acknowledging the discrepancy. Chuck Holmes, foreign editor for NPR Digital, expressed surprise at the error. The Factbook currently states only four percent of Botswana practice the indigenous Badimo religion. In reality most citizens follow traditions considered part of that faith. Scholars note some entries remain outdated despite regular updates. Richard Collin and Pamela L. Martin highlighted these issues in their 2013 book An Introduction to World Politics. The National Institute of Standards and Technology contradicts claims about metric system adoption. Three countries previously labeled as not adopting metrics are now committed to doing so including the United States as of 2023. These contradictions suggest potential reliability gaps even within official government publications. Users relying solely on this source may encounter conflicting information from other authoritative bodies.
