Population Estimates for States by Age and Sex
The U.S. Census Bureau released these population
estimates to the public in June, 1999. The estimates incorporate
revisions of estimates from previous years as well as the results
of special censuses and test censuses conducted by the Census
Bureau.
Age - The age of individuals is
age at their last birthday.
Population (Census) - The
April 1, 1990 census population is a count of the number of persons
residing in an area (resident population) as reported in the
1990 Census of Population or as subsequently revised. Revisions
to an area's 1990 census population count may occur as the result
of (1) post-1990 census corrections of political boundaries,
geographic misallocations, or documented under enumerations or
over enumerations, and (2) geographic boundary updates made subsequent
to the 1990 census, which include annexations, new incorporations,
mergers, etc. The closing date for these two forms of revisions
applied to this set of estimates was December, 1997.
Population (Estimate) - The estimated
population is the computed number of persons living in an area
(resident population) as of July 1. The estimated population
is calculated from a demographic components of change model that
incorporates information on natural change (births minus deaths)
and net migration (net domestic migration and net movement from
abroad) that has occurred in the area since the reference date,
such as April 1, 1990, the date of the 1990 census. Additional
information on the methodology used to produce these population
estimates is contained in Current Population Reports P25-1127
and at our Internet site: http://www.census.gov/population/www/method.html
Resident Population - These population
estimates are for the resident population. The resident population
of an area includes all residents (both civilian and Armed Forces
populations) living in the area. The geographic universe for
the resident population is the 50 states and the District of
Columbia. It excludes Puerto Rico and outlying areas under United
States jurisdiction. The resident population excludes U.S. citizens
residing abroad.
