Estimate of the population  (ESTIMATE of the population)

Estimates of the population 1 by size and composition at various dates in the past and present may be made by various methods, including many of the methods used for population projections (720-1). Demographic estimates 2 include estimates of the population and of such characteristics as fertility (601-1), mortality (401-1), etc. The annual estimates of population 5★ from the last census is carried out on the basis of the last census and vital statistics in subsequent years. Intercensal estimates 3 relate to dates intermediate to two or more censuses (202-1), and take the results of these censuses into account. The error of closure 4 is the difference between the size of a population enumerated at a new census and the population estimated for that census date on the basis of a previous census, the excess of births over deaths, and net migration (805-2) during the intercensal period. This difference represents the balance of errors in the data on births, deaths, net migration, and the coverage of the two censuses.

  • 3. Postcensal estimates take the results of a previous census into account, but not those of the next census.
