The subnational ageing tool enables users to compare a range of current and projected ageing indicators across different lower-tier local authorities, regions and countries in the UK. The tool contains demographic indicators (for example, median age and percentage aged 65 years and over) and other indicators, including economic activity at older ages, one-person households headed by an older person and life expectancy.

All data underlying the tool are available for download from the Local statistics web page (see Links to underlying datasets).

Description of indicators

Median age refers to the age where one half of the population is older and one half is younger.

Old Age Dependency Ratio (OADR) refers to the number of people aged State Pension age (SPA) and over for every 1,000 people aged between 16 years and up to the SPA.

% aged 65 and over refers to the percentage of the population aged 65 years and over

% aged 85 and over refers to the percentage of the population aged 85 years and over

% aged 0 to 15 refers to the percentage of the population aged between 0 and 15 years

% aged 16 to 64 refers to the percentage of the population aged between 16 and 64 years

% aged State Pension age and over refers to the percentage aged SPA and over. Projected values take into account future changes in the SPA in the current legislation.

% aged 16 years up to State Pension age refers to the percentage of the population aged between 16 years and up to the SPA. Projected values take into account future changes in SPA in the current legislation.

Sex ratio 65 and over refers to the number of males aged 65 years and over for every 100 females aged 65 years and over.

Sex ratio 85 and over refers to the number of males aged 85 years and over for every 100 females aged 85 years and over.

% one-person households aged 65 years and over refers to the percentage of one-person households in which the householder is aged 65 years and over.

% of one-person households aged 85 years and over refers to the percentage of one-person households in which the householder is aged 85 years and over.

Economic activity of those aged 50 to 64 years refers to the proportion of those aged 50 to 64 years who are either in employment or actively seeking employment.

Employment rate of those aged 50 to 64 years refers to the proportion of those aged 50 to 64 years who are employed.

Life expectancy (males and females) refers to the number of years a person, either male or female, can expect to live, on average, in a given population.

Points to note

Local authorities can be selected from the search box, interactive map or from the barcode charts.

Regions and countries cannot be selected directly from the map but can be displayed by selecting from the search box.

When looking at barcode charts, there may be multiple areas with the same value, but only one area will be displayed on the plot; data for all areas are available using the search function.

Data are shown to one decimal place; the exception is the OADR, which is shown rounded to the nearest whole number.

The map legend has been created using the Jenks Natural Breaks methodology; this defines where the breaks fall in the distributions of the indicators.

On 1 April each year, local authorities can change their boundaries (for example, by combining with another local authority). The map used in the tool will contain the most recent local authorities, but some of the datasets included may relate to older boundary configurations. Where this is the case, data will be unavailable for the area but can still be downloaded from the ONS website using the old boundary labels.

2018-based projections data for Welsh local authorities are currently unavailable. These data will be added to the tool once projections are published on the StatsWales website. For more information, please visit Wales national population projections.
