Education and fertility levels of individuals and communities are closely interlinked. Education-specific fertility rates are useful to understand how differences in educational attainment influence reproductive behaviour. These estimates also serve as foundations for designing and developing population projections under varying education and fertility scenarios. However, consistent series of historical education- and age-specific fertility rates are rarely available outside countries with strong vital registration systems. Here, we estimate education- and age-specific fertility rates for 78 countries within the Demographic and Health Surveys (DHS) database, spanning the period from 1970 to 2020, in five-year intervals. Using a Bayesian approach, we combine data from multiple sources to estimate UN-consistent education- and age-specific fertility rates.
