The Dynamics of Populations Large and Small: Processes, Models and Futures

  • Philip ReesEmail author
Part of the Understanding Population Trends and Processes book series (UPTA, volume 4)


This chapter is written as a reflection on population changes over the past and future half centuries. Demographic analysis focuses on the processes which add members to populations and which subtract members. The key population processes are therefore fertility which adds babies, mortality which subtracts mainly older adults and migration which adds and subtracts people mainly in the young adult ages. Migration operates on local, national and international scales. Only migration between spatial units alters their population. The chapter looks at both recent trends and the future. Societies that pay attention to their potential futures are normally more successful than societies that pay no attention. As individuals, we are interested in what might happen over our remaining lifetimes, over the remaining lifetimes of our children and grandchildren.
