Socio-economic differentials of under-five mortality in Botswana: an application of the indirect estimation method

Abstract Background Socio-economic differentials in infant and under-five mortality exist in all countries worldwide, but the extent of differentials varies across countries. This study aimed to examine the socio-economic differentials of under-five mortality in Botswana within the framework of equality and equity. Methods and findings The analysis for this paper was based on the data from 2001 and 2011 Botswana Population and Housing Censuses and the 2017 Botswana Demographic Survey. One census method was used to indirectly estimate under-five mortality for different socio-economic groups using Princeton west model life tables. Results from this study revealed that socio-economic disparities in under-five mortality disfavouring the worse-off exist in all the selected socio-economic variables. The variations of socio-economic groups by mother's place of residence and employment status have been narrowing over time, whereas the differences of socio-economic groups by mother's level of education and marital status have been widening over time. Conclusions The findings of this study show that policies and interventions targeted at reducing inequalities should reach all socioeconomic groups across the country. Differences of each society and localities should be considered while designing and implementing policies and interventions.
