Amongst other struggles, providing health care suitable for its population's needs remains a major challenge for Nigeria as a nation today. To assess the health of the population and the use of health care services, Nigeria's National Population Commission carried out Demographic and Health Surveys (DHS) in 1990, 1999, 2003, and 2008. Knowing that several states in Nigeria have populations dominated by one of the three major ethnic groups, my project used DHS data to examine how state of residence influences health measures, controlling for all other relevant factors. I used the ordinary least squares - multiple regression method in order to separately analyze the degree of influence each independent and control variable has on determining the aggregate health measures of each state. The health measures I focused on include child malnutrition and diarrhea, female circumcision, and maternal health behavior. In the past, studies have consistently revealed that amongst the three nationally dominant ethnic groups, Hausa people suffer the worst health measures for children and mothers; however, mixed results exist for how well Yoruba and Igbo communities fare relative to each other. This study aimed to clarify the relationship between Yoruba and Igbo dominated states using data from Nigeria's most recent and largest nationally representative sample yet - DHS 2008. I hypothesized that Igbo-dominated states fare worse than Yoruba-dominated states, because the Biafran War mostly damaged infrastructure in "Igboland", and reports indicate that the Yoruba region stands more highly urbanized today, which suggests greater postwar fitness. I also hypothesized that as the number of minority ethnic groups a state hosts increases, the worse the state-level health measures will be, according to predictions from social disorganization theory. If my results support my hypotheses, then Nigeria's future health initiatives should consider health disparities along lines of ethnicity and ethnic diversity within a state.
