This booklet briefly profiles the U.S. population and the changes it has undergone since the 1970 census. It focuses on population growth, migration, changes in the racial composition, male and female employment, income levels, poverty, and home ownership. Graphs are used throughout to identify changes from the 1970 census. Findings indicate that the rapid growth of the American population after World War II will probably not occur again; that the American population is shifting south and west, out of large cities, and to suburbs and the countryside; and that minority groups are growing faster than the population as a whole. Other changes include an aging population, more education, later age at marriage, more participation by women in the work force, a drop in the poverty rate, especially for senior citizens, more home ownership, and a slight income rise when incomes were adjusted for inflation.
