"Using Public Use Microdata Sample A from the 1980 United States Census, human capital measures are developed and used to test whether states experience human-capital migration that is significantly different from human migration. Strong evidence demonstrates that human-capital migration differs significantly from human migration. For example, Arkansas and Vermont are shown to have a net in-migration of people, but a net out-migration of human capital. Conversely, the data for Connecticut and Minnesota indicate a net out-migration of people and a net in-migration of human capital. This study suggests that traditional models of interstate migration mask the flow of human capital."
