Census 2021

All about the 2021 Census and the first release of census information on population.

The census is a survey that is carried out every ten years. It gives us the most accurate estimate of all the people and households in the district.
 

Results

The Office for National Statistics (ONS) has published the first results from the 2021 Census. This data provides information on the population and the number of households in local authority areas in England and Wales.

What the census found

In Uttlesford, the population size has increased by 14.9%, from around 79,400 in 2011 to 91,300 in 2021. This is higher than the overall increase for England (6.6%), where the population grew by nearly 3.5 million to 56,489,800.

As of 2021, Uttlesford is one of the least densely populated of all the local authority areas in the East of England, with around one person living on each football pitch-sized area of land.

Across the country the population has continued to age. In Uttlesford, there has been an increase of 36.3% in people aged 65 years and over, an increase of 10.5% in people aged 15 to 64 years, and an increase of 11.3% in children aged under 15 years.

  • housing
  • labour market and travel to work
  • sexual orientation and gender identity
  • education

Details of later releases can be viewed on the proposed outputs and release plans pages on the ONS website.
 

Why it is important

The census is a once-in-a-decade survey that gives the most accurate estimate of all the people and households in England and Wales. The information you give helps decide how services are planned and funded in your local area. This could mean things like doctors' surgeries, housing or new bus routes.

It asks questions about you and your household to build a picture of all of us. It looks at who we are and how we live. There's no other survey that gives as much information about our society and future needs.

Charities also use census information to help get the funding they need. Businesses use it to decide where to set up, which creates job opportunities.

The ONS has published some census stories showing how different organisations use census information to plan services.
 

Veterans and the census

Former armed forces personnel were, for the first time, be able to identify themselves as veterans in the 2021 Census.
 

Keeping your data safe

No one can identify you in the published census statistics. Your census record is kept confidential for 100 years and only then can future generations see it. Find more information about how your data is kept safe on the census website.

The ONS have also produced an animated video about keeping your data safe that you can watch on YouTube. This provides information about data and security for Census 2021 and explains how the ONS protects your personal information.
