The concentration of disadvantage and the rise of an urban penalty: urban slum prevalence and the social production of health inequalities in the developing countries.

Urban slums are proliferating in the developing countries. A corollary of this structural transformation is the increasing recognition of an urban penalty wherein slum populations exhibit notable inequalities in health relative to non-slum urban residents and even rural populations. The built urban environment, in turn, is a crucial context within which the social production of disproportionate morbidity and mortality is enacted. The authors develop this assertion and use bivariate and partial correlation analysis to highlight the association of urban slum prevalence, or proportion of the total population living in urban slum conditions, with indicators of mortality and gender parity, measured at the national level. Data for 99 developing countries show that greater urban slum prevalence is strongly correlated with higher levels of infant, child, and maternal mortality. Further, urban slum prevalence exhibits strong, deleterious correlations with gender parity (measured by the gender development index) and fertility rate, factors that have a crucial direct impact in shaping variant mortality levels. Future research is warranted on the social inequalities in health and illness derived from the expansion of urban slum conditions in the developing countries.
