Find out key UK census dates, when the next census will be released and more...

Census records are some of the most important resources for British family history. They help you track how your family changed over time and reveal information about your ancestors that you won’t find anywhere else. Historical censuses are held by The UK's National Archives and are also available as online records at Findmypast.

This handy guide explains the history behind UK census records, what they can tell you about your family history, and some important dates to watch out for now and in the future.

What is a census?

Censuses are recorded by governments periodically and act as population reports. The official meaning of a census from the Oxford Dictionary says it's;

"the process of officially counting something, especially a country’s population, and recording various facts."

Taking a census usually involves all householders completing census forms that list information about their lives and their family on a specific day periodically. A census taker or enumerator delivers and collects the household forms in their assigned area.

Why are censuses important?

The recorded population data is used by governments for planning things like healthcare, education and employment services at a national, regional and local level. From a genealogy perspective, historical census records are invaluable snapshots of your relatives at a given point in time.

How often is the census?

In the UK, censuses have been taken on a given census day every 10 years since 1801 with just one exception. The 1941 Census didn’t happen due to the Second World War.

That wasn't the only problem affecting census records during wartime. A fire in 1942 completely destroyed the 1931 Census for England and Wales. For family history, a useful way to bridge that unfortunate records gap is by using the 1939 Register as a census substitute.

When is the next British census?

The next census is scheduled to take place in 2031, a decade on from the most recent one on March 21, 2021. Statisticians have predicted that the 2021 Census could be the last of its kind as cheaper alternatives for gathering data are explored. The 2021 Scotland census has been postponed until 2022 due to the coronavirus pandemic.

Completing the census is your chance to leave your mark and help shape the future. Just imagine, generations from now, your descendants might be checking it to find out more about you.

UK census dates throughout history

From 1801 to 1831, census records were used to create summaries of localities and later destroyed. So, for family historians, the full censuses dating from 1841 to 1911 are the ones of real interest.

Here’s a brief summary on the history of British censuses and what these detailed family records can tell you.

1801 Census

The first UK census was taken on 10 March 1801. Only fragments like 1801 Kent, Dartford Census include details useful for tracing family history.

1811 Census

Taken on 27 May 1811, only summary counts of households were collected so it’s not very useful from a genealogical perspective.

1821 Census

Like those before it, only counts were taken for this census which took place on 28 May that year. You’ll find some exceptions that do include householder details for areas like Kent, Westminster, and Orkney.

1831 Census

This census was taken on May 30, 1831. Excerpts from Westminster, Sheffield and Shrewsbury survive, among others.

The first fully surviving UK census was taken on June 6, 1841.

Like previous censuses, details on names, ages, addresses and family relationships are included.

Once the 1881 Census was fully compiled, officials noted that there was an alarming rise in the number of individuals being reported as "deaf and dumb", compared to previous census returns. After inquiries were made, it transpired that many enumerators had recorded babies as being deaf and dumb simply because they could not speak.

For the first time, the UK census recorded a person’s employment status in 1891. This adds even more color as you build a detailed picture of your ancestors’ lives.

The 1911 Census was taken on April 2 that year. Until the release of the 1921 Census, it was often a must-search starting point for anyone new to British family history.

When will British census records next be released?

Due to UK privacy laws, 100 years must pass before the public can access census records. The 1931 Census took place on April 26 in England, Scotland and Wales. Northern Ireland was recorded as part of the 1926 Irish Census so wasn't included in the 1931 UK Census. Along with the information requested in 1921, the 1931 Census asked respondents about their usual place of residence. While the records for England and Wales were destroyed by fire, the 1931 Census for Scotland survives.

The next UK census was on April 8, 1951 with the records due to be released in 2052. It included questions on household amenities for the first time.

The UK census has continued every decade since the 1950s. Along the way, more and more questions were asked reflecting changes in British society. Technology was also introduced to make the process more efficient. In 1966, an additional census was taken trialing new methods of enumeration. The first question about religion appeared in 2001, while specific questions on civil partnerships first featured in 2011.
