Conception rates and unemployment rates at the national (A and B) and state (C) level. Conception rates are for US-born women only. “Conceptions” refer to conceptions resulting in live births. Straight lines in B and C are fitted using OLS. Observations are weighted by cohort size in C. Corresponding regression results are presented in SI Appendix, Table S1A. See Materials and Methods for the definition of conception and unemployment rates.
