Explore Census 2021 data for counties, unitary councils and London boroughs

The first outputs from Census 2021 are here. We have developed a Census 2021 Local Insight site to showcase these datasets for counties, unitary councils and London boroughs.

What data is available to explore?

ONS have published 63 datasets, details of which are available here.

All of these datasets have been added to Local Insight. The Census 2021 Local Insight site includes 25 of these:

  • All people 
  • People by 5 year age groups (19 datasets)
  • All Females 
  • All Males 
  • Population Density (Persons per hectare)
  • Communal establishment residents
  • Household residents

We have also included the 2011 counterparts for each of these datasets for easy comparison between 2011 and 2021 data.

We are also displaying some additional datasets for benchmarking purposes:

  • Index of Multiple Deprivation 2019 (IMD) Score
  • Unemployment benefit (JSA and Universal Credit) 
  • Children aged 0-15 in relative low-income families
  • Pensioners in poverty (Pension Credit)
  • Average house price

This is a small selection of the 1,100 datasets available in Local Insight, all managed and maintained by us. 

How to use the site

There is a full user guide available, which covers all aspects of the tool. There is also some initial information to get you started below.
