Migration, along with births and deaths, are the components that determine population change. Total net migration itself is a factor of two determinants: internal migration and international migration. Internal migration is the number of people moving from one area in the county, state, or nation to another, while international migration tracks the movement of the foreign-born and the emigration of the native-born. Because people move to areas that offer the jobs they need and the quality of life they desire, net migration is a useful tool in assessing the strengths and weaknesses of a region, both economically and socially. Understanding the composition of a community, especially stemming from international migration, helps businesses and local governments predict the community’s changing needs, and plan for changes in service demands. Residual net migration accounts for natural net increases by employing the following formula: Residual net migration = (population in the latter year – population in earlier year) – (births – deaths).
