The first round of data from the 2021 census was published on 28 June by the Office for National Statistics (ONS). Data is available at a local authority level and includes:

• Usual resident population by sex and 5 year age band;
• Usual resident population density; and
• Number of households.

To help you use and understand the data, we have developed a suite of resources, including:

• a dashboard comparing 2001, 2011, and 2021 data;
• data (including Welsh metadata) in InfoBaseCymru; and
• a guide to Census 2021.
