Free access is available to the 1921 Census within the Library building through Findmypast.
This is the latest census to be released and the most detailed, as it includes information regarding education and names of employers.
The next census, the 1951 census, will not be available until 2052 because the 1931 census was lost in a fire and no census was taken in 1941 due to World War II.

A census has been taken in England and Wales every ten years since 1801 with the exception of 1941. However, no personal details were collected for the early returns only statistical information. 1841 was the first census that contained any information that is of use to the family historian, including name, age, address, occupation and in later returns details of place of birth, infirmity and from 1891 - language spoken - English, Welsh or both.
The original household schedules from 1841 to 1901 were copied by the enumerator into enumerator's books, these are the records that are available to view today, the original household schedules were subsequently destroyed. However, the 1911 census is different, this was the first census for which the original schedules were preserved and made available.
The 1921 census is the latest available, it is the most detailed census to date and will be the last to be released until 2052, as the 1931 census was lost in a fire and no census was taken in 1941 because of the Second World War.
