The most recent census released for England and Wales, taken on Sunday 19 June 1921, is now available as a transcript to MyHeritage subscribers. There are 38,335,681 entries.
Records typically include names, gender, age at last birthday, year and place of birth, occupation details, relatives and other household members, and residence information.
The census day, 19 June, had been pushed back owing to widespread industrial action. Being summer time, you may well find people recorded on holiday rather than at their usual residence.
There is no access to images of the original. Treat the transcript with caution. For my grandfather, I found discrepancies with the information in the image available on Findmypast.
I guess better than nothing for MH subscribers who can’t afford Ancestry or FMP, but I agree, definitely tree those indexed results with caution!
