Talk:Bills of mortality/to do


 * Source for date included christenings.


 * Nomenclature: The bills became the "old bills" in 1840 but continued to be used as an area for stats. The Registrar General area known variously as "new bills", "table of mortality" and "Registrar General's Bills of Mortality". Need so summarise/source this.


 * Problems with the bills as reliable statistics


 * The parish clerks tried to promote a bill in parliament to improve the bills


 * Cost of production: appears to have come from baptism/burial charges [depopulation of central London reduced this income]
