About
What this site is, where the data comes from, and how updates work.
Source archive
Country pages are built from a public Factbook JSON archive (derived from historical Factbook data), then reformatted into a consistent structure for fast reading and navigation.
Update policy
Pages are periodically regenerated as the archive is improved and as additional modern sources are added. When newer figures are incorporated (e.g., population, GDP, infrastructure), the page will note the estimate year and the source used for that field.
Corrections
If you spot an error or want to suggest a better source, email hello@theworldfactbook.org.
