Phase three - Alternative Census 2021 population data
In phase three, we will publish datasets on four data types.
Alternative population bases
These are different places where individuals could’ve been counted, such as workplace or location out of term-time.
Or, they might be different populations, such as short-term residents born outside the UK.
These are small groups of the population with the same cultural background, such as an ethnic group, national identity or religion.
We publish information across a range of different variables for this specific group.
You can find out more about alternative and small population data (opens in a new tab) on the Office for National Statistics (ONS) website.
Origin-destination or “flow” data
These show the movement of people from one place to another, for example, moving from overseas, or to and from a second address.
You can find out more about origin-destination or “flow” data (opens in a new tab) on the ONS website.
These are small samples of census records, with all identifying information removed, for approved researchers.
You can find out more about microdata samples (opens in a new tab) on the ONS website.
