... and logistic regression for our analyses of preterm birth and low birth weight using clinical cutoffs. We present the bivariate relationship between heteropatriarchy and birth outcomes (model 1), followed by a multivariate model that includes all of our controls (model 2). All models adjust for population...

While directly standardized rates are widely used, they depend upon the selection of an appropriate standard population and give disproportionately heavy weight to the high ages. Average of relatives indexes give equal weight to all ages, but are infrequently used...

Exploiting variation across counties and over time, we find a negative relationship between the incidence of low-weight births and the level of economic mobility as measured in adulthood for the county birth cohorts in our sample. Our results build on a large and growing...
