Glossary
Births
Total number of live births occurring to residents of an area during a time period, as estimated using reports from the Census Bureau's Federal-State Cooperative Program for Population Estimates (FSCPE) and the National Center for Health Statistics. The birth rate expresses births during a time period as a percentage of an area's population at the midpoint of the time period.
Deaths
Total number of deaths occurring to residents of an area during a time period, as estimated using reports from the Census Bureau's Federal-State Cooperative Program for Population Estimates (FSCPE) and the National Center for Health Statistics. The death rate expresses deaths during a time period as a percentage of an area's population at the midpoint of the time period.
Estimated Components of Population Change
Occurrences used by the Census Bureau to estimate changes in the population during a time period. These components consist of births, deaths, net internal migration and net international migration.
Natural Increase
Births minus deaths. The rate of natural increase expresses natural increase during a time period as a percentage of an area's population at the midpoint of the time period.
Net Internal Migration
The difference between internal in-migration to an area and internal out-migration from the same area during a time period. Internal in- and out-migration consist of moves where both the origin and the destination are with in the United States (excluding Puerto Rico). The net internal migration rate expresses net internal migration during a time period as a percentage of an area's population at the midpoint of the time period.
Net International Migration
International migration, in its simplest form, is defined as any movement across U.S. (50 states and District of Columbia) borders. The U.S. Census Bureau makes estimates of net international migration for the nation, states, and counties. We estimate net international migration as: (1) net migration of the foreign born, (2) net movement from Puerto Rico, (3) net movement of the U.S. Armed Forces, and (4) emigration of the native born. The largest component, net migration of the foreign born, includes lawful permanent residents (immigrants), temporary migrants (such as students), humanitarian migrants (such as refugees), and people illegally present in the United States. Currently, we do not estimate these components individually. The Census definition of foreign born is available on the foreign-born population page.
Net Migration
Net internal migration plus net international migration. The net migration rate expresses net migration during a time period as a percentage of an area's population at the midpoint of the time period.
Population Estimate
The estimated population is the calculated number of people living in an area as of July 1. The estimated population is calculated from a components of change model that incorporates information on natural change (births, deaths) and net migration (net internal migration, net international migration) that has occurred in an area since a Census 2000 reference date.
