Intercensal estimate in the field of demographics is an estimate of population between official census dates. Some nations produce regular intercensal estimates while others do not. Intercensal estimates can be less informative or more informative than official census figures, depending on methodology, completeness, accuracy and date of data, and can be released by nations, subnational entities, or other organizations including those not affiliated with governments. They differ from population projections. They also can have significant undercounts or overestimates.

[edit] By country

• Indonesia's BPS releases province by province annual estimates for all provinces, regencies, and kota in Indonesia, with some provinces more up to date than others.

• Brazil's IBGE releases regular annual estimates for all states and cities in Brazil.

• Canada's Statistics Canada releases regular quarter annual intercensal estimates for provinces and territories in Canada.

• Japan releases regular monthly intercensal estimates for all prefectures and cities in Japan.

• The United States Census Bureau releases regular intercensal estimates of total population of the country, states, and metropolitan areas annually. Unincorporated areas are counted only during censuses. California compiles annual estimates separately from the Census Bureau, which includes unincorporated areas and differing methodology.
