Results from censuses before the 1960s are in printed reports. More recent output has been both printed and electronic, with increasing amounts becoming available online.

Printed reports

Printed reports, to be laid before Parliament and published, have been produced from all censuses. All findings were in printed reports until the 1966 Census, when it was first released on electronic media. The number of printed pages reached its maximum in 1991, but was reduced in 2001 with the rapid shift to electronic media.

A complete set of the printed report is available for public access by arrangement in the Office for National Statistics (ONS) Library in Newport, and Census Customer Services will provide advice on obtaining figures from historic reports on request. There is no central list of library holdings of historic census reports, but the British Library holds a set, and university libraries may also hold the reports. Major local reference libraries often hold historic reports.
