Next release of data – topic summaries

The next Census 2021 data releases will be a series of eight topic summaries. The ONS will publish the first of these in October 2022 and the last by the end of 2022. The exact timing of these releases within this window is yet to be announced, but the ONS will confirm each publication at least four weeks in advance. Each topic summary will include data tables for single variables (univariate) down to the most detailed geographies. The order of release of these topic summaries is:

    1. Demography and migration
    2. Ethnic group, national identity, language and religion
    3. UK armed forces veterans
    4. Housing
    5. Labour market and travel to work
    6. Sexual orientation and gender
    7. Education
    8. Health, disability, and unpaid care.

The ONS will provide further updates to its plans for the release and publication of Census 2021 data on its website: ONS plans for publication of Census 2021 outputs.

Following completion of Phase 1, the ONS will begin Phase 2 of the census outputs programme. This is when multivariate data and more complex analysis based on usual resident population will begin to be released, and this is expected to be published between Winter 2022 and early 2023. Phase 3 will then follow from Spring 2023, and this will see the start of publication of data related to alternative population bases, small population data, origin destination data and micro-data.
