This analysis examines the institutional context of infant mortality i
n Peru using economic, social. health care, and public health measures
as indicators of development and equity. Using linked data from popul
ations and economic censuses, government agencies, and health surveys
on twenty-four Peruvian provinces, I explore how economic development
and institutional contexts influence health outcomes. Regional inequit
ies based on rural population, subsistence activity, women's illiterac
y, monthly income, Gross Domestic Product, medical care, and health fa
cilities are compared Then a cluster analysis identifies institutional
contexts that have internal similarities. These contexts are able to
discriminate differences in infant mortality, My conclusion is that un
derstanding regional inequities - defined in terms of economic develop
ment, social institutions, and health services - leads to enhanced exp
lanations of disparities in health outcomes.
