We aim to publish all main Census 2021 data on the population of England and Wales within two years of the census.

You can see what we have published on the release calendar.

Interactive content

We have created several interactive products using Census 2021 topic summary data. You can use these products to find facts and figures about areas in England and Wales.

Census maps is an interactive tool to explore Census 2021 topic summary data across England and Wales for different topics down to a neighbourhood level. Explore your area on the Census maps page.

You can also access area profiles, which allow users to view statistics from across different topics for a particular area. Alternatively, you can draw your own area and create a custom area profile.

To tell the local stories from Census 2021 topic summaries, we have published interactive reports for every local authority in England and Wales. These articles and charts highlight the most interesting changes in that area. Look at how your area has changed in 10 years.

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.

Phase 2: Starting from March/April 2023

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 moved the release of this alternative population into phase two.

Get information about the datasets we have produced for Non-UK Born Short-term Residents.

Phase 3: from Summer 2023

National Parks

There are 10 national parks in England and 3 in Wales. Each national park is managed by its own national park authority, a special-purpose local authority. For more information please see National park residents, England and Wales: Census 2021.

Approximated social grade data

Social grade is a socio-economic classification. This means a way to group people by type mainly based on their social and financial situation. Marketing industries use it to help analyse consumer markets.

Get more information about the data we have produced on approximated social grade.

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, national identity, and main language. Examples of small populations that we have produced datasets about include:

  • British Sign Language (BSL)

  • Caribbean

  • Cornish

  • Jain

  • Kashmiri

  • Nepali

  • Ravidassia

  • Sikh

Get more information about datasets we have produced 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 have produced 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.
