"On February 4, 2026, the CIA made the surprising decision to shut down the World Factbook after more than sixty years of operation. This move was not just a simple website update. By removing the site and setting up redirects that lead away from historical data, the agency effectively broke millions of links used in schools, news reports, and scientific research. The takedown also removed all historical archives of the World Factbook. The takedown of this resource is a significant blow to the world of open data and public knowledge.
"The World Factbook began in 1962 as a secret tool for intelligence officers but eventually became the most popular public reference for global information. Its value was rooted in the fact that it was a public domain resource. Unlike private encyclopedias, anyone could use Factbook data for free without asking for permission and it became a standard reference material in school libraries. When I was a kid, we had both print and CD-ROM versions available to use in school projects at Errol Consolidated Elementary School in New Hampshire. It provided an accessible way to look at statistics about every country on Earth, covering everything from geography, to health, to government structures. One of the coolest features was the public domain photographs and documents that CIA operatives contributed from their field operations.
"The CIA has offered no explanation for the takedown. The line is likely going to be that the World Factbook 'no longer effectuates agency priorities' or is not necessary for agency operations and mission. However, there are consequences to other federal agencies and initiatives that either contribute to, or depend upon, data provided by the Factbook. It relied heavily on the U.S. Census Bureau and its International Database. The Census Bureau provided demographic and economic data, such as population growth, migration trends, and GDP, while the Factbook made that data easy for the average person to read. It also helped track global progress toward the United Nations Sustainable Development Goals, usually led by the Department of State and the US Chief Statistician in the Office of Management and Budget (who is required by law to coordinate international statistical activities of the United States). Since these interagency collaborations are not free, Census gets reimbursed for the work it does with other agencies. It’s unclear how the end of the World Factbook will impact the contributions Census received to its International Database budget from CIA. Resourcing for this critical database already took a major hit in 2025 with the shuttering of USAID, which also reimbursed Census for data it contributed to their international statistical work.
"The end of the World Factbook is a reminder of how fragile public access to federal data can be. Federal data is paid for by taxpayers and should remain available to them. Losing the official site makes it harder to access reliable statistics about the world and breaks the chain of historical record. There are a few options to access archived versions of the site. Developer Simon Willison created both a GitHub repository and a browseable live version of the 2020 archive of the site (that was the last year the CIA provided full zip archives). The Internet Archive’s WaybackMachine has taken over 28,000 snapshots of the World Factbook since January 20th, 2017.
"Data preservation initiatives that seek to save public resources like the World Factbook from erasure, whether contributed by individuals like Simon, community-led like the Data Rescue Project, or established organizations like the Internet Archive need support to be sustainable. To that end, I purchased the domain worldfactbook.us and will hand it over to anyone interested in funding, developing, and maintaining an open-source full-stack restoration of the World Factbook."
