Notes

Census Day was the 21st of March 2021. The ONS perturbs every count slightly to protect privacy, each cell on its own, so a council's categories can add up to a total a few people different from one topic to another, and its councils add up to England's and Wales's counts only within a few dozen.
By council as the ONS's Census API gives them, its lower-tier local authorities of 2023, with Barnsley's and Sheffield's figures under the codes they had until the 1st of April 2025, as the API gives them. Scotland's and Northern Ireland's censuses are separate, so their councils are not here.
Every council's categories together count all its usual residents, “Does not apply” those the question was not asked of.
The ONS's description of the topic, “UK armed forces veteran indicator (5 categories)”: Identifies people who have previously served in the UK armed forces. This includes those who have served for at least one day in armed forces, either regular or reserves, or Merchant Mariners who have seen duty on legally defined military operations.
The ONS's quality statement: Take care when comparing characteristics of UK armed forces veterans and non-veterans, as veterans are mainly male and older. Not adjusting for this fact can lead to misinterpretation, as variables such as health strongly relate to age and sex.
