PB - National Bureau of Economic Research N1 - March 2002; Hardcopy version available to institutional subscribers N2 - This paper examines the racial gap in infant mortality rates from 1920 to 1970. Using state-level panel data with information on income, urbanization, women's education, and physicians per capita, we can account for a large portion of the racial gap in infant mortality rates between 1920 and 1945, but a smaller portion thereafter. We re-examine the post-war period in light of trends in birth weight, smoking, air pollution, breast-feeding, insurance, and hospital births UR - https://www.nber.org/papers/w8836 UR - http://dx.doi.org/10.3386/w8836 ER -
