Both indicators included have been derived from the published 2018 mid-year population estimates for the UK, England, Wales, Scotland and Northern Ireland. These are sex ratios for people aged 65 years and over and 85 years and over. A sex ratio shows the number of males in the population for every 100 females.
This dataset has been produced by the Ageing Analysis Team for inclusion in a subnational ageing tool, which will be published in early summer 2020. The tool will enable users to compare latest and projected measures of ageing for up to four different areas through selection on a map or from a drop-down menu.
