The Oxford Centre of Population Research (OXPOP) is an area of research within the Department of Social Policy and Intervention, promoting research into demographic problems that face the world in the 21st century. OXPOP aims to monitor and project demographic trends, analyse their underlying causes and consequences, and evaluate the challenges and opportunities that they present as well as their links to the physical, economic and social policy environment. Researchers in OXPOP have developed a demography blog, openpop.org to raise the profile of and facilitate discussion around demographic issues.
