A general bill of Christenings & Burials in London from December 12 1820 to December 11 1821
This bill of mortality lists the deaths and christenings in London for the year December 12 1820 and December 11 1821. Bills of mortality were introduced in London in the early 16th century primarily to record incidences of the plague. Information was collated by Local Parish Clerks who had no medical knowledge and often defined the causes of death themselves. A sheet summarising the year's births and deaths was published annually.
