To outline racial and ethnic groups, demographers depended on the U.S. decennial census and annual Current Population Surveys (CPS). To calculate marriage, fertility, and mortality rates, demographers use the national vital statistics records of births, marriages, and deaths. Estimates of internal migration come from the U.S. Bureau of the Census (USBC), and estimates of international migration come from the Immigration and Naturalization Services and USBC.
Explanation:
Population size is determined by three principal metrics of demography: mortality, fertility, and migration. Racial and ethnic differences in rates of one or more of these metrics cause the racial composition of the nation to change.
