The report presents the results of a study which indicate that demographic comparisons of labor force participation rates are most fruitfully made on the basis of sex, age, educational attainment, presence of small children, race, and marital status. Also that the most important demographic comparisons of groups employment (unemployment) rates are framed in terms of educational attainment, age, family status, sex, and race. Demographic attributes indicated as significant for in-migration are primarily age, sex, and educational attainment. It is typically the interaction of these characteristics that leads to widely varying labor market behavior. (NTIS)
