The Census Population Act of 1800 established a national census for England, Scotland and Wales every ten years starting in 1801. This census was only a count of accommodation, people and occupations.

Useful Census Returns

The 1841 census was a complete change and asked for more detailed information rather than just numbers. Each district was divided into a number of enumeration districts, each of which was the responsibility of an enumerator. The enumerator delivered a form known as a schedule to each household a few days before census night, and collected the completed schedules the day after.  The schedules were then sorted, and the details copied (transcribed) into the census enumerators’ books. It is these books which have survived for 1841 to 1901 and which can be seen today online or on microfilm. Be aware that in many cases a household could overlap to a second page if there was not enough room to write them all on one page.

You will find what appears to be a lot of crossings out, but these are usually tick marks, made by the enumerator when he was counting people, ages, occupations or places of birth etc.   There are also marks to divide households, as they could share a house.

census marks


Once the census returns had been collected, collated and counted, a report was written covering different aspects of what the returns as a whole showed regarding migrations, jobs and housing.  The reports covering 1801 to 1931 can be seen at the Histpop website:

Special schedules were provided for ships and institutions such as workhouses, hospitals and boarding schools etc.


When were they taken?

The dates the census returns were taken vary, so it is a good idea to know the dates as it can help you with your family timelines.

The dates are given below.  The returns were supposed to reflect who was in the house at midnight on these dates, however on occasions you may find your relative is listed at two places at the same time, once at their usual home address and again at the address they where that evening, perhaps as a lodger or with other family members.

  • 6th June 1841
  • 30th March 1851
  • 7th April 1861
  • 2nd April 1871
  • 3rd April 1881
  • 5th April 1891
  • 31st March 1901
  • 2nd April 1911 – this is the last census return currently available
  • 19th June 1921  – this will not available until 2021 and probably not online until 2022.
  • 26th April 1931   – Destroyed by fire in WWII
  • 29th Sept 1939  – Register for issuing of ID cards – except service personnel. This is now available on several subscription websites.
  • 1941  – No census due to WWII

Due to our privacy laws the census returns are sealed for 100 years, so we will not see the 1921 census until at least 2022 as it takes about one year to transcribe and digitalise them.

What they contain:

The full details of what the census returns contained can be found that The National Archives website.

Addresses were shown for each household but house numbers were rarely given, and in rural areas you will often find only the name of the village or hamlet.

The 1841 census has an age column BUT ages were usually rounded down to the nearest five for those aged 15 or over. This means that if someone was 29 years old, the age would be written as 25.

This census also does not give places of birth.  Instead the question was ‘were you born in this county?’  If your ancestor lived in one county but was born in another county, the place of birth would show N for No, but would not indicate where he was born, Otherwise it would be a Y for Yes. If he was not born in England or Wales the return would show an S (Scotland), I (Ireland) or F for other Foreign Parts.

Relationships between the people living in each household are not given in the 1841 census.  Do not assume these relationships. The woman you assume is the wife may be a sister, cousin or sister in law.

From 1851 to 1901 the format of the census returns and the range of questions asked remained largely the same, but were made more precise.   Relationship to the head of the household (usually the oldest male), were now given, although some relationships could still be confusing as ‘sister’ could also be ‘sister in law’, and ‘cousin’ could be a distant uncle etc. Full ages (at last birthday) are now given, and marital status (shown as condition), with U, Um or S as unmarried/single, m – married and w – widowed, is also listed. Single women with children may show themselves as being widowed.  Places of birth are also more precise listing parish and country of birth in born in England or Wales.

Remember that in these days not many people could read or write, a literate neighbour or child may complete the form.  Places of birth may also change across different census returns, depending on who gave the answers.  A parent would know a child was born in one village but grew up in another one. When that child has their own household, they may think they were born in the place they grew up.  Likewise a husband may assume his wife was born in the place he thought she came from.


The 1911 Census

The original householders’ schedules were all destroyed once the information had been copied into the enumerator’s books. By 1911 most people were literate enough to complete the household schedules so the 1911 census is the first time we see the original household schedules, written by our ancestors, along with the signature of the person who completed the form.

 Additional questions related to the married woman’s ‘fertility in marriage’ and asks for:

  • the length of present marriage
  • how many children had been born to that marriage
  • how many of those children were still living
  • how many of the children had died

The last two numbers should add up to the total number of children, but you may be surprised how many do not. Be aware that if the family contained an illegitimate child then these numbers and the length of the marriage may be changed to ‘legitimise’ the child.

1911 was the time of the suffragette movement and many women disagreed with having to complete the census when they were not allowed to vote.  For this reason you may see comments such as “Votes for Women” written across the page.  Some women even refused to be included in them.  If your ancestor did this it will give you an idea of their beliefs.

Additional pages

Some subscription websites show not only the household pages, but you can also navigate to find description of the Enumeration District. These usually include exact details of boundary for that return, and sometimes the route taken.  This can be very helpful in identifying where your ancestor lived when the address is simply given as the village name.

Enumerators description of the area

The 1911 census, as explained earlier, is different to the earlier returns and each page had a front cover.  If your relative had not written the address on the return, try to check the frontispiece as that should have the full address on it.

You can view these extra pages on the Ancestry website by clicking on the  filmstrip icon at the bottom of the images.

Missing ancestors or pages

Your ancestor could be missing from the census for any number of reasons, and these have been discussed in a blog on the National Archives (TNA) website: Missing from the census? by Audrey Collins.

One reason you may not be aware of is that all census’s having missing or lost pages.  Sadly the 1861 Census is the worst affected.   If you cannot find your ancestor, search the TNA online catalogue for “missing” and restrict your search to the reference for that census; HO 107 for 1841 and 1851, RG 9 for 1861, RG 10 for 1871 and so on, up to RG 14 for 1911. This will usually show which part of a parish or district has not survived.
