Population Estimates Terms and Definitions

----------------------------------------------------------------

Base Population - The population count or estimate used as the starting point in the estimates process. It can be the most recent updated Census count or the estimate for a previous date within the same vintage. The April 1, 2010 estimates base population may differ from the April 1, 2010 Census count due to legal boundary updates, other geographic program changes, and Count Question Resolution actions.

Births - Total number of live births occurring to residents of an area as estimated using reports from the National Center for Health Statistics (NCHS) and the Federal-State Cooperative for Population Estimates (FSCPE). The birth rate expresses births during a specified time period as a proportion of an area's population at the midpoint of the time period. Rates are expressed per 1,000 population.

Deaths - Total number of deaths occurring to residents of an area as estimated using reports from NCHS and FSCPE. The death rate expresses deaths during a specified time period as a proportion of an area's population at the midpoint of the time period. Rates are expressed per 1,000 population.

Group Quarters Population - All U.S. residents who live in group living facilities including correctional institutions, juvenile facilities, skilled nursing facilities, college residence halls, military barracks, group homes, and workers' dormitories.

Natural Increase - Births minus deaths. The rate of natural increase expresses natural increase during a specified time period as a proportion of an area's population at the midpoint of the time period. Rates are expressed per 1,000 population.

Net Domestic Migration - The difference between domestic in-migration to an area and domestic out-migration from the same area during a specified time period. Domestic in- and out-migration consist of moves where both the origin and the destination are within the United States (excluding Puerto Rico). The net domestic migration rate expresses net domestic migration during a specified time period as a proportion of an area's population at the midpoint of the time period. Rates are expressed per 1,000 population.

Net International Migration - Any change of residence across the borders of the United States (50 states and District of Columbia). The international migration rate expresses net international migration during a specified time period as a proportion of an area's population at the midpoint of the time period. Rates are expressed per 1,000 population.

Net Migration - Net domestic migration plus net international migration. The net migration rate expresses net migration during a specified time period as a proportion of an area's population at the midpoint of the time period. Rates are expressed per 1,000 population.

Numeric Population Change - The difference between the population of an area at the beginning and end of a time period.

Percent Population Change - The difference between the population of an area at the beginning and end of a time period, expressed as a percentage of the beginning population.

Residual - Population change that cannot be attributed to any specific demographic component of population change.
