A little bird informs me that Findmypast will be moving the 1921 census of England and Wales to the regular subscription in January. I found no independent source.
Findmypast has a history of initially making exclusive databases available on a premium basis, capturing the consumer surplus from those anxious for information. That happened before with the 1911 census and the 1939 Register. The lower-cost makes examining those on outlying branches of the family tree, neighbours and associates affordable.
Wow – interesting… I imagine knowing that as soon as that exclusivity period ends in January ’25, Ancestry will make a bid for access. It will be interesting to see how long it takes for them to get it up and running.
