That's interesting Melba,
Thanks for posting.

I thought it might be useful if people have been rather confused if they find a person in the 1921 census in an asylum/mental hospital, or have found a death certificate up to 1921, and yet couldn't find an admission on the Ancestry indexes. So this explains why! I should note that on the census people in asylums/mental hospitals were more often listed with initials, I think by 1921, first initials and surname, but earlier I think all initials (first name, surname, but sometimes reversed) were sometimes used which makes it difficult to find people - Ancestry's search setting 'exact' seems to be more useful for this. Also I think by 1921, and perhaps 1911 exact birthplaces were usually given, but earlier often nothing was put.
If anyone wants to check my methodology - go to the search page and put in 1912 in the Institution Place - Year box, click exact, it gives 22,876 results, 1911 gives 23,777, 1910 21,458. If you put in 1913, 1914, 1915 etc. up to 1921, no results
