Assessing the Temporal and Regional Differences in the Relationships between Infant and Child Mortality and Urban Slum Prevalence in Less Developed Countries, 1990-2005

Drawing from various bodies of social scientific literature and research, the authors assess the extent to which infant and child mortality rates in less developed countries are impacted by the percentage of domestic populations living in urban slum conditions. Results of two-way fixed effects panel model estimates of 80 less developed countries from 1990 to 2005 indicate that growth in the percentage of populations living in urban slum conditions positively affects both forms of mortality rate. The effects, moreover, are much more pronounced for African countries than for less developed countries in Latin America and Asia and moderately larger for the Asian nations than those in Latin America. Additional findings suggest that the magnitude of the effect of urban slum prevalence on infant and child mortality increased through time for the African countries, but not for the Latin American and Asian countries in the study.
