Table 4 Education by birth cohort interaction models: linear and non-linear specifications

Predictor	OR	95% CI
Parent education interaction model 1
Linear education levels	1.12***	(1.09 to 1.15)
Birth cohort	1.27***	(1.23 to 1.31)
Education × cohort	.99**	(.99 to 1.00)
Parent education interaction model 2
12.5 to 15 years of education	.73***	(.64 to .82)
0 to 12 years of education	.49***	(.41 to .58)
Birth cohort	1.22***	(1.18 to 1.26)
12.5 to 15 years of education × cohort	1.05**	(1.01 to 1.09)
0 to 2 years of education × cohort	1.08***	(1.04 to 1.13)

All covariates displayed in Table 1 and log of income-to-needs effects were controlled in these models. For interaction terms, significant odds ratios less than 1 indicate a narrowing selection gap between families with relatively high versus low levels of the covariate in question. **p < .01; ***p < .001.
