The US Natality files provide information on medical procedures and health related behavior during pregnancy and childbirth. The data set represents nearly the universe of mothers who give birth in the US, providing the most complete coverage possible of medical care and health behavior among a specific patient population. We document gaps in outcomes by education of the mother and the changes in these educational gaps during 1989-2002.
