Demographic data based on the U.S. census of 1980 are presented and compared to data from the 1970 census. A series of charts, maps, graphs, and tables provide detailed statistical data on such things as population growth trends, population by race and age, educational achievement, number of people living alone, male and female occupations, percent homeowners, and so on. A narrative account elaborates on the information found in the charts and tables. The information may be summarized briefly as follows: It is unlikely that the U.S. population will ever again grow as rapidly as during the 20 years following World War II. The population is moving south and west, out of large cities, and to suburbs and the countryside. Minority populations are growing at a faster rate than the rest of the population. The population is aging and will continue to grow older. More people are living alone, and families are smaller. The population as a whole is better educated than earlier generations. People are marrying later than they used to. Slightly over half of all women are now in the work force. Incomes rose in the 1970s, but the gains were largely offset by increases in the cost of living. The poverty rate dropped slightly during the 1970s for the total population, but it dropped substantially for senior citizens. More people are buying their own homes, despite higher costs. Classroom teachers can use this resource for research projects and lecture material. (JB)
