About this dataset

This dataset provides Census 2021 estimates that classify usual residents in households in England and Wales by disability, by general health, and by age. The estimates are as at Census Day, 21 March 2021.

Protecting personal data

Sometimes we need to make changes to data if it is possible to identify individuals. This is known as statistical disclosure control. In Census 2021, we:

  • Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we 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, we might 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 we applied perturbation.

About the variables

Disability (5 categories)

Description: People who assessed their day-to-day activities as limited by long-term physical or mental health conditions or illnesses are considered disabled. This definition of a disabled person meets the harmonised standard for measuring disability and is in line with the Equality Act (2010).

Comparability with 2011: Broadly comparable. The question related to this variable was split into two parts for Census 2021. In Census 2021 we asked people completing the questionnaire if they have any physical or mental health conditions or illnesses. In the 2011 Census, people were asked if they have a health problem or disability. We also removed the option to include information about problems related to old age.

General health (3 categories)

Description: A person's assessment of the general state of their health from very good to very bad. This assessment is not based on a person's health over any specified period of time.

Comparability with 2011: Highly comparable

Age (9 categories)

Description: A person's age on Census Day, 21 March 2021 in England and Wales.

Quality information: Estimates for single year of age between ages 90 and 100+ are less reliable than other ages. Estimation and adjustment at these ages was based on the age range 90+ rather than five-year age bands.

Comparability with 2011: Highly comparable
