Research Themes


For more than five decades, cutting edge methodological and empirical approaches have defined our work, helping us better measure, understand, and predict population change and its impact. We study populations and the processes that affect them from many different angles, whether the focus is on adolescents in the US, mothers in the Philippines, or the elderly in Africa. And we provide access to our data, collection protocols, and methods, which have influenced scholarship and practice across the globe.
