Census day was held on Sunday 21 March 2021 and was the first 'digital-first' Census with 89% of households in England and Wales responding online.

Overall the response to Census 2021 exceeded expectations, with 97 per cent of households across England and Wales returning their Census questionnaires. Further information about return rates can be found on the ONS website.

What is the Census?

The Census is a once-in-a-decade survey that gives us the most accurate estimate of all the people and households in England and Wales. It has been carried out every decade since 1801, with the exception of 1941 and is organised by the Office for National Statistics (ONS).

The Census 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.

It includes questions about your sex, age, work, health, education, household size and ethnicity. And, for the first time in 2021, there was a question asking people whether they have served in the armed forces, as well as voluntary questions for those aged 16 and over on sexual orientation and gender identity.

Release of Census Data

The ONS has now started to release Census data by topic. As each set of data is released, we are producing summary reports detailing the key findings.

Please note that throughout the summary reports where a percentage increase of decrease is shown this denotes a change in percentage point(s) e.g. 'The proportion of residents aged 16+ years without qualifications is 12.6% and shows a decrease of 1.0% from the previous Census' describes a decrease from 13.6% in 2011 to 12.6% in 2021.

Accessing data from the Census

The Census provides a very rich source of information about the population. The quickest way to discover what information is available from the 2021 Census is to visit the Census Topic Summaries page on the Nomis website.

All univariate was released as part of phase 1 of the Census schedule and it can be accessed through the ONS Census 2021 website. Multivariate data  has also been released, and it can be accessed through the ONS ‘create a custom dataset’ tool, and Nomis ‘Ready-made tables’ (limited combinations). Please note that some of the datasets use statistical disclosure control to maintain confidentiality of individuals and therefore some data combinations might show incomplete data.

Alternative sources are the Office for National Statistics website. The ONS have aslo developed a story map. The ONS plan to release detailed analysis of Census data.

Why the Census is important

It's important that we all take part in the Census. The Census helps us understand what our society needs now and what it will likely need in the future. The information it collects helps with decisions on the planning and funding of services in your area.

Iain Bell, deputy national statistician at the Office for National Statistics describes the importance of the Census as follows: "A successful Census will ensure everyone from local government to charities can put services and funding in the places where they are most needed. This could mean things like doctors' surgeries, schools and new transport routes. That's why it is so important everyone takes part and we have made it easier for people to do so online on any device, with help and paper questionnaires for those that need them."

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.

Why the Census went ahead in 2021 when we were in lockdown

The ONS who run the Census released a statement about the importance of going ahead with the Census in 2021 and how it ensured everyone can be safely counted in the context of the coronavirus (COVID-19) pandemic. Please see the following link for the ONS statement on why the Census went ahead

No doubt some Census data was impacted by the pandemic and the fact that a stay at home order was in place when it was taken, for example travel to work patterns during this time and the ONS provides information on the impact that the pandemic may have had on travel to work Census 2021 data.
