This term is used mostly in connection with national population and housing censuses. Other common censuses include censuses of agriculture, traditional culture, businesses, supplies, and traffic censuses.

The list includes sovereign states and self-governing dependent territories based upon the ISO standard ISO 3166-1. The list also includes unrecognized but de facto independent countries. The figures in the table are based on areas including internal bodies of water such as bays, lakes, reservoirs and rivers.

Culturally Caribbean mainland countries are included.
