UK census records, 1841 to 1921

What each census from 1841 to 1921 recorded, where to search them free and paid, the 1931 and 1941 gaps, Scottish and Irish differences, and how to read an enumerator's page.

The census is the family historian's favourite record because it shows the whole household at once. Taken every ten years, it lets you follow a family from 1841 to 1921, watch children arrive and leave, and read off the birthplaces that point you to the parish registers. Here is what each one contains, where to find it and how to read it.

What each census records

1841Name, age (rounded down to the nearest five for adults), sex, occupation, and whether born in the same county (Y/N) or in Scotland, Ireland or "foreign parts". No relationships, no exact birthplace. Useful but thin.
1851 to 1901Name, relationship to the head of household, marital status, exact age, occupation, parish and county of birth. 1851 onwards adds disabilities; 1891 adds the number of rooms (if under five) and, in Wales, language spoken; 1901 adds employer/worker status.
1911The first census where the original household schedules survive in the householder's own handwriting. Adds years married, children born alive, still living and died (the "fertility" columns), and industry as well as occupation.
1921Adds place of work and employer's name, whether parents are alive or dead (for children), and age in years and months. Released in 2022 and the last one available.

There is no 1931 census for England and Wales (destroyed by fire in 1942) and none was taken in 1941. The 1939 Register fills the gap. The 1931 Scottish census survives and is due for release in 2032.

Where to search

Reading an enumerator's page

Each page shows a street or part of one, with households separated by a slash or double slash. Note the schedule number, the full address, and every person in the household, including servants, lodgers and visitors: a visitor is often a relative, and a lodger sometimes marries the daughter. The "where born" column is the single most valuable field, but treat it loosely: people gave the nearest market town, the parish they grew up in rather than the one they were baptised in, or a different answer every decade.

Ages and names are approximate

Adults' ages in 1841 were rounded down, and in every census people misremembered, rounded or shaved a few years. A woman who is 38 in 1861 and 45 in 1871 is normal. Names appear as the enumerator heard them: Elizabeth as Eliza or Betsy, a surname spelled three ways across three censuses. Search by first name, approximate age and birthplace when the surname fails, and use wildcards.

When you can't find them

Using the census to drive the research

Each census household gives you the births to look for (children's ages and birthplaces), the marriage to look for (the eldest child's age), and the parents' birthplaces for the parish search. Record every household you find with its full reference (year, piece, folio, page or schedule) so you can cite it; see organising your research. Then confirm the links with certificates and parish registers.
