The World Factbook

The World Factbook, also known as the CIA World Factbook, is a reference resource produced by the Central Intelligence Agency (CIA) with almanac-style information about the countries of the world. The official print version is available from the Government Printing Office. Other companies—such as Skyhorse Publishing—also print a paper edition. The Factbook is available in the form of a website that is partially updated every week. It is also available for download for use off-line. It provides a two- to three-page summary of the demographics, geography, communications, government, economy, and military of each of 267 international entities including U.S.-recognized countries, dependencies, and other areas in the world.
Microstate
A microstate or ministate is a sovereign state having a very small population or very small land area, and usually both. The meanings of "state" and "very small" are not well-defined in international law. Recent attempts, since 2010, to define microstates have focused on identifying political entities with unique qualitative features linked to their geographic or demographic limitations. According to a qualitative definition, microstates are: "modern protected states, i.e. sovereign states that have been able to unilaterally depute certain attributes of sovereignty to larger powers in exchange for benign protection of their political and economic viability against their geographic or demographic constraints." In line with this and most other definitions, examples of microstates include Liechtenstein, Monaco, San Marino, Andorra, the Cook Islands, Niue, and the Federated States of Micronesia.
