All the rates are expressed per 1,000 population. 

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.

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.

Net International Migration - Any change of residence across the borders of the United States (50 states and District of Columbia). The estimates of net international migration are made up of four sub-components:

  1. Net international migration of the foreign born;
  2. Net migration between the United States and Puerto Rico;
  3. Net migration of natives to and from the United States; and
  4. Net movement of the Armed Forces population between the United States and overseas. 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.
