Documentation notes:

The population estimates for states incorporate revisions of estimates from previous years and the results of special censuses and test censuses conducted by the Census Bureau.

Age - The age of individuals is in terms of age at their last birthday. 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 on the Census Bureau website at:

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.
