AbstractPsychic costs reflect differences in interregional utility, an important determinant of population among regions. Following Sjaastad's definition of psychic costs, the consumer surplus foregone by Appalachian migrants in two urban areas was measured as the difference between current urban income and an acceptable income level in eastern Kentucky. Psychic costs varied significantly with the size of the city of destination; migrants' demographic characteristics; and their satisfaction with jobs, city services, and interpersonal relationships in the city. Mobility which reduces psychic costs contributes to social well‐being but will not be measured in national economic accounts.
