The collection released on 6 January 2022 covers England and Wales. The 1921 Census for Scotland will become available to search later in 2022. The 1921 for Ireland was never taken due to the events surrounding the Irish War of Independence.

How many people were enumerated for England and Wales?

37,885,242 persons; 18,082,220 males and 19,803,022 females (Histpop. Part II, statistical notes, p. vii)

What information does the 1921 Census for England and Wales contain?

This census is the most informative yet for family historians.

New information not available on previous censuses includes:

  • Place of employment
  • Industry in which employed
  • Materials worked with
  • Name of employer
  • Marital status for those 15 or older (with ‘divorce’ as a status for the first time on the census)
  • Details of whether or not parents still alive for those under 15
  • Whether the person spoken an additional language (for returns in Isle of Man and Wales)

Were different questions asked for the 1921 Census (in comparison with previous surveys)?

Yes quite a few!

  • Ages were given in years and months.
  • Those aged 15 or over were asked whether they were single, married or divorced (divorce had not been specified as an option in previous census decades). 
  • Details of employer and place of work were enquired about, as the answers were hoped to shed light on how far people were travelling to work, and what their transport requirements would be.
  • The ‘famous’ fertility question of the 1911 Census was removed. Rather than asking for the duration of marriage and the age of the children, simply the number and ages of living children under 16 were required.
  • Those aged 15 or under were asked to specify if one or both of their parents had died, and if just one, which one.
  • The disability question was also absent from the 1921 Census, as it was deemed an unreliable means of obtaining accurate information.

Why isn’t there a 1931 Census for England and Wales?

On the night of Saturday 19 December 1942 the Office of Works, Hayes, Middlesex caught fire – seemingly from an accidentally discarded cigarette (not enemy action, which might be supposed from the 1942 date), which smouldered with disastrous consequences, despite there being six firewatchers on duty at the location that night.

The Office of Works was the location at which all of the 1931 Census records for England and Wales were stored. The fire raged to such an extent that there were no records deemed worth salvaging at the time as a consequence.

How did the Scottish 1931 Census records survive?

They were stored in Edinburgh, so avoided the conflagration that destroyed the English and Welsh census.


Searching the 1921 Census

How to do a basic search of the 1921 Census

Note: you do not need a subscription to Findmypast in order to use the 1921 Census and you do not need to take out a 14 day free trial. You do need to register with the website however.

Once you are logged in you will be able to conduct searches at no charge.

Find My Past 1921 Census

Note that when searching you are entering the year of birth, but the ‘Where’ field is not for place of birth. The ‘Where’ field is for you to enter the place in which you expect the person to be in 1921.

The search results give a detailed combination of facts to help you determine whether the entry is correct before you decide to buy a full transcription or the digitised image of the original page. This is an example of the search results above.

The details include: first name(s), last name, birth year, place of birth, and the name of the parish, registration district and county where the person was living in 1921.

What you can see once you’ve paid

The details on the transcription for Robert Henry Adams, ‘artificial limb' maker, tell us that he was in the employment of C. Blatchford. Blatchford Prosthetics (www.blatchford.co.uk) is a Victorian company that is still in business today. In 1921 it is very likely that its clients included injured service personnel.

The prices are £2.50 to purchase the transcription and £3.50 for the digitised image (Pro subscribers to Findmypast have free access to the 1921 Census for England and Wales as part of their subscription (as of 11 October 2022); regular subscribers receive no discount).

It’s not just an image – it’s images

In addition to the household image, the £3.50 fee includes the front of the census form (on which you’ll find the address), the cover of the form (on which you will find the series and piece number), contemporary maps, details and plans of division (which comprise details similar to the enumerator’s description in earlier census returns). To find the image of the front and the image of the cover, whilst looking at the household image page click on ‘Extra (Address)’ – found near the bottom right-hand corner of the window.

Note: The address is found on the image of the front of the form, not on the household image page (which we are used to expect from the 1911 Census of England and Wales for instance).

How to do an address search

For census images you’ll find the household schedule number [No. of schedule.] in the top right-hand corner of the census household page. In this instance, it's 182.

For census transcriptions you’ll find the piece number and household schedule number included in the transcription.

How to use RD codes to help identify a place

For instance, you can use the Registration District and Sub-District code to work out a county name if this has not been included on your set of household census images.
