  1. Sample consists of women age 15–44. The comparison group encompasses all observations from New York, Chicago, Philadelphia, Baltimore, Cleveland, Houston, San Diego, New Orleans, Tampa St. Petersburg, and Portland. The control variables in column (1) include MSA and year dummies. The control variables in column (2) include MSA, year, age, ethnicity, and family income dummy variables as well as the number of previous births by the individual and MSA-level lagged male and female unemployment rates. The control variables in column (3) include all the control variables in column (2) plus the level of completed education of an individual. The control variables in column (4) include all the control variables in column (3) plus a dummy variable for marital status. The control variables in column (5) include all the control variables in column (4) plus an interaction term for ethnicity and education and an interaction term for ethnicity and marital status. Sample weights are used in all regressions. All specifications are estimated by OLS. Robust standard errors are in parentheses. ***p value < 0.01, **p value < 0.05, *p value < 0.1
