Examining the inter-linkages of population growth, poverty and natural resources in Tanzania

Ayoub S Ayoub, University of Nevada, Las Vegas

This study presents an empirical analysis of relationships between population growth via fertility rates, natural resources deterioration, and poverty in Tanzania. The study uses recent household data from the Demographic and Health Surveys. Unlike previous studies, this study uses a negative binomial model which is considered appropriate for the dependent variable used. This study is unique because it employs three models to distinguish combined rural and urban, rural, and urban populations. The findings indicate that water scarcity is associated with lower fertility rates in two of the three models used, and that higher levels of family wealth are associated with lower fertility rates for all three models. These findings provide evidence for Malthusian pressures by suggesting that population growth coupled with poverty leads to resource depletion, which in turn acts as a check on population growth by lowering fertility rates.
