Census 2021

Census 2021: Population and Households (June 2022)

Census 2021: Demography and Migration in Wirral (November 2022)

Census 2021: Ethnicity, National Identity, Language and Religion for Wirral (December 2022)

The census is undertaken by the Office for National Statistics (ONS) every 10 years and gives us a picture of all the people and households in England and Wales.

The census asks questions about you, your household and your home. In doing so, it helps to build a detailed snapshot of our society. Information from the census helps the government and local authorities to plan and fund local services, such as education, doctors' surgeries and roads. 

The latest census was conducted in 2021, with ONS releasing data in a phased approach.

Population and households (28th June 2022)

Start of the Census 2021 analysis programme

All Census 2021 data releases will be published with statistical commentary. A detailed three-year Census 2021 analysis programme will start after the release of topic summary data. Get more information about what we plan to publish in the first year of the analysis programme.

Multivariate data for the usual resident population base

Multivariate data will allow you to combine variables and explore relationships between the data, collected from Census 2021 on the usual resident population of England and Wales. We are introducing new functionality for Census 2021 data that will allow you to make your own datasets, as well as view and download ready-made datasets. Get more information about the new functionality and our plans to release multivariate data.

Short-term resident population data

The short-term resident population includes those who were not born in the UK and who intended to stay in the UK for less than 12 months, as of March 2021. Following user feedback, we have moved the release of this alternative population into phase two.

Alternative population bases

Alternative population bases are the different geographical locations where individuals could have been counted for Census 2021. Examples include workplace, workday and out-of-term populations.

Small populations

Small populations are groups that are defined by their cultural background, including characteristics such as ethnic group, country of birth, religion and national identity. Examples of small populations that we are committed to producing datasets about include Cornish, Kashmiri, Nepali, Sikh, Ravidassia and Jain.

Get more information about datasets we will produce and those we are considering to produce on alternative and small populations.

Detailed migration data

Detailed migration statistics provide the characteristics of people or households who have moved within the UK or from another country into the UK during the year before the census.

Get more information about the datasets we will produce on detailed migration.

Origin-destination data or 'flow' data

Origin-destination data describes the movement of people from one location to another. Planned types of origin-destination data from Census 2021 include:

  • migration flow data
  • workplace flow data
  • second address flow data
  • student flow data

These datasets will be classified as either public, safeguard or secure. Get more details about our plans, including how you can access origin-destination data.

Microdata samples

Microdata are samples of anonymised records for individuals and households, which include a selection of associated census characteristics. Microdata samples will be classified in three ways: public, safeguarded or secure.

Read more details about our plans including how you can access microdata samples.

UK census data

Censuses took place in England and Wales, and Northern Ireland in March 2021. Scotland's census took place in March 2022. We are working closely with UK census offices to publish comparable data from across the UK.

Get information about how we are working with the other UK census offices and our plans for UK census outputs.
