According to an announcement from The National Archives (in Kew, Richmond, Surrey, England):

"Today we can announce two regional hubs that will provide free online access to the 1921 Census of England and Wales from 6 January 2022.

"The census will be available online via our commercial partner Findmypast and will be free to access in this way at The National Archives, in Kew.

"In addition, visitors to the Manchester Central Library and the National Library of Wales will be able to access the 1921 Census of England and Wales via the Findmypast website for free following its publication next year.

"Access at the Manchester Central Library, on St Peter’s Square, Manchester, will be supported by the Manchester and Lancashire Family History Society helpdesk and the Archives+ Team.

"The publication of the 1921 Census of England and Wales is the culmination of almost three years’ work by Findmypast’s highly skilled team of conservators, technicians and transcribers.

"It is the largest project ever completed by The National Archives and Findmypast, consisting of more than 30,000 bound volumes of original documents stored on 1.6 linear kilometres of shelving, as outlined in two special guest blogs exploring the vast digitisation and conservation project."
