Notes. OLS regression coefficients reported, with standard errors presented in parentheses. All regressions include indicators for ethnicity and sex. Whitehall II regressions also include controls for age and age squared at phase 1. In all regressions, the benchmark for father’s social class is unskilled. The chi-square tests for equality of coefficients test the null hypothesis that the coefficients on the father’s class indicators are equal across columns 1 and 2 (BCS) and across columns 3 and 4 (NCDS).
