In Scotland, National Records of Scotland takes responsibility for historical census data. NRS have stated they will be releasing their indexed images of 1921 Census returns for Scotland on www.scotlandspeople.gov.uk and in the ScotlandsPeople Centre in the latter half of 2022.
As with Scotland, Ireland and Northern Ireland conducted their own censuses separate from England and Wales. However, The 1921 Census was not taken in Ireland due to the Irish War of Independence. Censuses in Ireland and Northern Ireland were conducted in 1926.
