p<0.05 two-tailed test.

a

Reference group is White.

b

Mother’s and respondent’s education are continuous and centered at 12.

c

Age is centered at 32.

d

Unconditional model variance estimates: u0i =3.968, u1i=0.273, u2i=0.011.

e

Change in the −2LL contrasts Model 1 to the unconditional model (not shown); Model 2 to Model 1; and Model 3 to Model 2; Model 4 to Model 1; Model 5 to Model 4; Model 6 to Model 3 (top estimate); and Model 6 to Model 5 (bottom estimate).

f

Adjusting for nativity of respondent and respondents’ mother and father; birth cohort; birth cohort×age; birth cohort×age-squared; mortality; mortality×age; and mortality×age-squared.

g

Adjusting for community at age 14, family structure at age 14, and area of residence at age 14.

h

Adjusting for time-varying measures of occupational status, community, and marital status.
