Due to the lack of authoritative contemporary sources, estimates of the population of England for dates prior to the first census in 1801 vary considerably. It has been suggested that even the 1801 census may have left up to 250,000 people uncounted.
1801 - 8,308,000 at the time of the first (one off) census (probably underestimated) Census officials estimated at the time that there had been an increase of 77% in the preceding 100 years. In each county women were in the majority.
