CUPC brings together an interdisciplinary community of scholars, across three University of Colorado campuses, dedicated to research and training in population science with broad focus on health, migration and environmental demography. By providing administrative, technical and development support, CUPC facilitates collegial interaction and nourishes collaboration across several departments, institutes, and universities. An important aspect of the Center is a high level of collaboration between faculty and graduate students. Center affiliates explore demographic processes in the US and a variety of international settings while applying their expertise to yield high quality, policy-relevant research and training. Current initiatives focus on large-scale research initiatives, complex data collection efforts, and new methodological and statistical approaches.
