This paper uses data from the National Longitudinal Survey of Youth to estimate sibling correlations in educational attainment and cognitive ability and to investigate whether these correlations vary systematically with family or sibling pair characteristics. Similar to previous authors, I estimate raw sibling correlations of .46-.57 for educational attainment and .62-.67 for cognitive ability and I find that observable differences in family background between families can account for less than half of these correlations. An analysis of the residual sibling correlations in status shows that the degree of sibling resemblance varies systematically with characteristics of the family and the sibling pair. In particular, sibling correlations in status appears to be U-shaped in father's education (a proxy for family permanent income), implying that siblings from middle income families have less similar outcomes than siblings from both rich and poor families. There is also some evidence that the sibling correlation in status is smaller for siblings far apart in age, which suggests that time-varying components of family environment have a non-trivial impact on eventual socioeconomic status.
