factbook.json - 260+ Public Domain (Free) Country Profiles Updated- Pop, Internet,...
Hello, I’ve updated the /factbook.json archive (repo). What’s news? All 260+ country profiles updated using the latest (live) pages from the CIA World Factbook site. The /factbook.json archive now follows 1:1 the “official” structure e.g. All country profiles now use the two-letter GEC (formerly FIPS) codes e.g. au for Austria, gm for Germany, and so on. All country profiles are now included e.g. all oceans, the world, the gaza strip, the west bank, etc. The country profiles now get organized / stored by region as used / assigned by the World Factbook. Cheers. PS: Use the factbook command line tool and scripts to build your own up-to-date country profiles.
