Primary Contributing Factors to Change
The primary contributing factors resulting in population change are 1) natural change (births less deaths) and/or 2) net migration. Eight tables are presented below providing annual data for each component county of the metro and metro summary. The tables provide data on the total population, births, deaths, natural change (births less deaths), international migration, domestic migration and net migration.
