Projected indicators included are derived from the published 2018-based household projections for England and 2018-based household projections for Scotland for the years 2018 up to 2043. The indicators are the percentage of one-person households, in which the householder is aged 65 years and over and the percentage of one-person households, in which the householder is aged 85 years and over. This dataset has been produced by the Ageing Analysis Team for inclusion in the subnational ageing tool, which was published on July 20, 2020 (see link in Related datasets). The tool is interactive, and users can compare latest and projected measures of ageing for up to four different areas through selection on a map or from a drop-down menu. Note on data availability: England, Wales, Scotland and Northern Ireland independently publish subnational household projections. Each country publishes a different set of age breakdowns and only England and Scotland provide the breakdowns required to calculate the indicators included above.
While there are many similarities in the methods used to produce household estimates and projections for the four countries of the UK, there are some important differences between the methods used and these affect the comparability of the results. The similarities between the methodologies mean that it is possible to broadly compare the results for the four countries. Although, users should be aware that any differences may be partly because of the different methods used to produce the projection results.
