We are excited to announce that we have released the first results from Census 2021 in England and Wales. 

We have published five datasets containing population and household estimates for England and for Wales, rounded to the nearest 100, at local authority level. These are: 

• usual resident population by sex 
• usual resident population by 5-year age group 
• usual resident population by sex and 5-year age group 
• usual resident population density 
• number of households 

To explain the data, we have published two statistical bulletins, one focused on England and Wales and one focused on Wales. In these, we discuss the population size and change from 2011, population density and number of households.  

To support the data, we have published a: 

• Quality and Methods Information (QMI) report, about the quality of the data 
• Maximising the quality of Census 2021 population estimates report, an overview of the estimation and quality assurance processes we used to create and ensure the estimates are fit for purpose 
• Local authority comparison tool, letting you compare estimates for local authorities with other sources of data 

We have also published interactive content from the Census 2021 first results, including a: 

• scrolly-telling article, about how the population has changed in different local authority areas and how they compare with others across England and Wales 

• game, testing your knowledge of the population of local authorities
