Most studies on early-life mortality compare mortality rates between large groups of births, such as across countries, income groups, ethnicities, or times. These studies do not measure within-group disparities. The few studies that have looked at mortality across the entire population of births, however, have used tools from the income inequality literature. Using a large data set from India, we estimate mortality risk for over 400,000 births using a Bayesian hierarchical model. We show that while measures based on the income inequality literature, such as Gini indices, are not appropriate for mortality risk, most of the variance in mortality risk occur within-groups of births. We developed a novel approach to investigate inequality in mortality risk. Our approach uncovers several important patterns in the dynamics of inequality in infant mortality and has broader applicability to other health outcomes.
The CHIPTS’ Methods Core hosts a monthly seminar series, which are one-hour workshops on research and statistical methods. The seminars are open to HIV researchers, faculty, students, and community. To see previous seminars, check out the Methods Seminar tag or you can find seminar videos on our Youtube Channel! This series is hosted by the Center for HIV Identification, Prevention, and Treatment Services (CHIPTS) and made possible by funds from the National Institute of Mental Health (MH058107).
