Deletion of Census Day

Comment: At first I thought , no way that secondary sources could be found for this. But if you search on "celebrate Census Day" you find governors declaring it a special day, people gathering in parks, the Victorian Society celebrating the 21st modern census http://www.victoriansociety.org.uk/publications/category/the-victorian/. This seems to be a real thing. –&nbsp
