Although in-migration and out-migration levels of communities or counties are usually positively correlated, little work has been done on the correlation between in-migration and out-migration within population subcategories. Using a special 1980 data source from the U.S. Census Bureau, this paper examines migration patterns in 30 age/education categories of the adult population in the 653 counties of Arkansas, Illinois, Louisiana, Kentucky, Mississippi, Missouri, and Tennessee. The categories crossed five age groups with six educational levels. The correlation between in-migration and out-migration was not very strong in itself, but was strongly affected by the relative educational levels of in-migrants and out-migrants, and only very weakly affected by their relative ages. When educational levels were the same, correlations were positive and reached as high as .60. When educational levels of in-migrants and out-migrants differed, in either direction, correlations became negative. Counties that were destinations for highly educated persons also lost many such persons, and also lost significantly fewer of their people with low levels of education. For counties with colleges or universities, the highest average correlation at the same levels of education was .38 when in-migrants were one age category younger than out-migrants. Counties characterized by simultaneous in-migration and out-migration of persons with low educational attainment were mostly rural Kentucky counties in or near Boone National Forest.
