Whites and small MSAs are the excluded categories in the regressions. In product-moment correlations, comparisons are versus all others.

All other calculations in this table use the MID approach (see text).

Cases are weighted to adjust for initial probability of selection, absenteeism during the base-year data collection, and panel attrition.
