Immigration (migration to a country) is one component of international migration; the other component is emigration (migration from a country). In its simplest form, international migration is defined as any movement across a national border.
The U.S. Census Bureau makes estimates of net international migration for the nation, states, and counties in the United States. These estimates are based in part on data collected in censuses and surveys. Projections of the U.S. population are also made using assumptions about net international migration.
