General description

Census 2021 included a question for the first time, asking people whether they had previously served in the armed forces or not. In November 2022, the Office for National Statistics (ONS) published 'UK armed forces veterans, England and Wales: Census 2021', which helped form Welsh Government's publication 'UK armed forces veterans in Wales (Census 2021)'.

This table is based on Census table TS071, 'Previously served in the UK armed forces'. The table provided Census 2021 estimates that classify usual residents aged 16 years or older in Wales and England by whether or not they have previously served in the UK armed forces. This does not include people who are currently serving in the UK armed forces.

For Census 2021, the ONS made changes to the data (called statistical disclosure control) so that it is not possible to identify individuals. These changes included:
• Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, they swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority.
• Added small changes to some counts (cell key perturbation), for example, change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when perturbation is applied.

This causes small changes to cells but does not fundamentally impact the meaning of the data. Where tables are made in different ways, the changes applied will be different, leading to differences between totals and tables not ‘adding-up’ to their totals. To minimise this, the ONS recommends where possible using totals from tables with fewer cells, at higher geographies. For example, if you wanted population by age you should use data from TS007 and if you wanted population by sex you should use data from TS008.

More information about the processes used in statistical disclosure control will be provided in future publications.

Users, uses and context

The data presented here are used by central government departments and local authorities for a range of purposes including for resource allocation, planning and monitoring of services, and as denominators for the calculation of various rates and indicators.

Rounding applied

To note the sums of local authorities may not add up the Wales figures due to the statistical disclosure methods applied to the data as described in the general description. Figures across different tables may also not match exactly due to statistical disclosure control methods applied to the data.
