Populations
Lead analyst: Doris Hain
The number of people and their age are the most important determinants of health need and utilisation. It is important to understand the size and age distribution of the population in determining current service delivery and to understand population change for planning future services.
ONS is the standard source for official population statistics and their population estimates and projections can now easily be found and downloaded from the reorganised ONS website. For the convenience of some of our users, who preferred to obtain these files from erpho and not directly from ONS, we keep the links to pre-2010 data alive. However, we do not intend to continue this practice and would like to refer you to ONS for standard geography populations from 2010 onwards.
