Gender difference is not statistically significant, based on linear or logistic regression models for each employment or life course stage category with female as sole predictor.

Within-gender difference between omitted employment (did not work, is not in the labor force) or life course stage (young, single, childless) and focal category is not statistically significant, based on linear or logistic regression models with categories of employment or life cycle stage as sole predictors.
