I know that and it took several years before every one used it, thats where some budding genealogists run aground trying to trace their ancestors. But Dobbo's on about the populaton in 1828, if a 1821 count is being used then it was 7 years out of date. I can give you more accurate figures for Old & New Accrington for 1666, but it does not list those below the age of 14.
Another thing which grounds many genealogists,was the change over of the gregorian & julian calenders, the change to new year being Jan 1st instead of Easter,if not converted correctly it can make children appar to have died before they were born
