Note: Table figures represent estimated age-by-period interaction terms coded to sum to zero in weighted logistic APC-I Models 1a for whites and Model 2a for blacks. Models 1a and 2a modeled white and black women’s labor force partication using age, period, and their interactions without covariates.
