Thanks to all who have taken the time to reply.
First let me correct a few misconceptions about the census and confidentiality.
The 1921 census (and all later census) was carried out under the regulations imposed by the Census Act, 1920.
Nowhere in the Census Act, 1920 is there mention of closure for 100 years.
In 1991 the Census Act, 1920 was amended by the Census (Confidentiality) Act 1991.
Nowhere in the Census (Confidentiality) Act 1991 is there mention of closure for 100 years.
The hundred year rule that people love to keep mentioning has no basis in law. It is (as the Office of National Statistics (ONS) describes it) a non statutory rule. I.E. It does not have the backing of statute (law).
However the ONS on one hand states there is a statutory prohibition but then claims they are going to release the census in 100 years.
The prohibition actually lasts forever there is no time limit on it.
This means that if it is possible to release it in 100 years it is possible to release it today.
If you do not believe me take a look at the legislation.
There is a transcript of the Census Act, 1920 on my website at
http://freepages.genealogy.rootsweb.ancestry.com/~framland/acts/1920%20Census%20Act.htmThere is also a link to the Census (Confidentiality) Act 1991 on that page.
The Lord Chancellor's Instrument No. 12 of 1966 established the 100-year embargo rule. Prior to that, the delay in making census records public had been much shorter. For example, the 1841 and 1851 census records for England and Wales were both released in 1912. Scottish records were also held for less than 100 years. The 1891 Scottish returns, for instance, were made public after a delay of only 64 years. Given that the release of returns after 50 to 80 years was the practice in the first half of the last century, and that the Lord Chancellor's Instrument No. 12 of 1966 was 55 years away at that point, I would be very surprised if anyone who participated in that census really believed that their return would be held for exactly 100 years and not a day less. What is more, section 5(1) of the Public Records Act 1958 provides for the general release of records after 50 years, and that was reduced to 30 years in 1967.
Only six out of the 15 pre-1910 United Kingdom censuses have been closed for 100 years.
The details of nine out of 15 have been released after less than 90 years. (source Hansard 29 March 2004).
I should also point out that it was not until 1981 that census schedules carried the assurance that the census would be closed for 100 years.
This means only the 1981, 1991 and 2001 census carried that assurance.
It should also be noted that in this day and age any sensitive information such as medical conditions etc can easily be redacted as has been shown by the release of the 1911 census.
