Joshua Wilde is a Senior Scientist and Researcher at the Leverhulme Centre for Demographic Science at the University of Oxford. His research focuses on demography, demographic economics, and development economics, with particular emphasis on the causes and economic effects of fertility change. Key areas include the macroeconomic effects of fertility decline in low- and middle-income countries, the relationship between climate change and fertility, the impact of health shocks such as COVID-19 and malaria on fertility and prenatal mortality, and the effects of gender discrimination on birth and economic outcomes. He is the co-creator of the Canning-Karra-Wilde (CKW) model, a leading tool for calculating the Demographic Dividend, and has published in prominent journals including the American Economic Review, European Economic Review, Demography, and Population and Development Review. He serves as one of two Editors of Population and Development Review and co-chairs the IUSSP Panel on Covid-19, Fertility, and the Family.
He recently secured a £1.7 million UKRI Frontier Research Grant, converted from an ERC Consolidator Award, to lead the SEXRATIO project examining the determinants of natural sex ratios at birth. Wilde is also a Research Scientist at the Population Research Center at Portland State University and a Research Fellow at the IZA Institute for Labor Economics. Prior to joining Oxford, he served as Deputy Head of the Laboratory of Fertility and Well-Being at the Max Planck Institute for Demographic Research and as an Assistant Professor of Economics at the University of South Florida. He consults regularly for organizations including the World Bank and the United Nations.
