We created a migration and earnings history from the National Longitudinal Survey of Youth to analyze the effects of youth county poverty rates on the adult earnings of white male migrants. We estimate a log wage equation that includes human capital measures, migration types, county poverty rates, and a rural–poverty rate interaction variable. Growing up in a rural county has a negative impact on adult wages independent of youth county poverty rates, but the rural effect is significantly greater for those who grew up in high poverty counties. Youth county poverty rates indirectly affect wages through the returns to migration.
