2021 and Beyond

All three UK census offices are planning for modified traditional censuses in 2021. The census topic coverage is broadly comparable to previous decades, but with important changes to how the data are collected. We anticipate a full range of census outputs to become available including aggregate data for areas, data about migration and travel flows between areas, samples of anonymised microdata, digital area boundaries and postcode directories, and ongoing linkages to the three UK census longitudinal studies.

As with comparable censuses internationally, the 2021 census design places primary emphasis on internet completion and the aim is for over 70% of questionnaires to be returned online. A series of Census Rehearsals were held across the UK in 2019 to make sure all the necessary operational processes worked properly. Parallel work by the census offices is focused on using data from administrative sources to potentially provide ongoing estimates for some traditional census variables, and it is likely that some administratively-sourced data (on income and number of rooms) could be directly included in the census outputs. In all countries, administrative data will be used in census quality assessment.

Consultations

The UKDS Census Support team take an active interest in census plans on behalf of users, attend advisory groups and prepare generic consultation responses. However, the nature of modern consultations make it impossible to adequately reflect the breadth of all users concerns and we encourage all individuals who use, or plan to use, future census data to contribute directly to census consultation processes. We anticipate an ongoing series of consultations in all parts of the UK, which will be increasingly focused on the specification of census output products.
