Resumen: The aim of this article is to test the effects of human capital on Spanish internal migration, decomposed into two components: the size and the composition of the labour force. Our results indicate that those Spanish regions that experienced increases in the ratio of skilled to unskilled workers attracted less immigration in the period 1965 to 1984. Between 1985 and 2000, when employment rates turned nonsignificant in determining migration, the opposite was observed.
