ESRC Centre for Population Change (CPC) biannual newsletter. Read articles on the latest research findings on population change. Funded by the Economic and Social Research Council, CPC is investigating how and why our population is changing and what this means for people, communities and governments. The pattern of our lives is continuously changing; many of us now remain in education for longer than in the past, we delay becoming parents and we are living longer than ever before. The households we live in are more complex with more step- and half-kin but also more of us live alone at some point in our lives. Many of us move around locally, nationally and internationally for work and family. Our behaviours interact to create the society in which we live. CPC research aims to understand the causes and consequences of changes in births, deaths, relationships and migration to enable policymakers and planners to know how, when and where to respond. By finding out, we can improve our world.
