World Population Program

Human population trends are a key factor in sustainable development. We study and project how the changing composition of population matters for social, economic and the environmental change and how human health and well-being are being affected.

Human population matters for sustainable development in two important ways. First, it is an agent of change, bringing about many of the environmental, economic, and social changes that continually challenge the sustainability of our current development paths. Second, the human population and its living conditions are the ultimate objects of development, with long-term human survival, health and well-being serving as criteria for judging whether or not development is sustainable.
