Abstract
This article describes some of the policies behind the decline of infant mortality in Sweden during the 20th century, from very high levels and large social differentials at the turn of the 19th century to one of the lowest levels in the world by 1950. Political commitment to reducing infant mortality and disparities between groups, a more equitable distribution of economic resources, and a successful combination of universal social and health policies most benefiting the least advantaged families and their children contributed to this favorable development.
