Graunt implies that for the figures before 1629 he was forced to have recourse to the unpublished records in the Parish Clerks Hall, and Dr Ogle suggests that the earlier figures preserved by Stow may have been obtained by that antiquary in a similar way. On the other hand letters of the sixteenth century, preserved at the State Paper Office, show that in times of infection the weekly figures were known to many persons. Perhaps the facts were regularly ascertained after 1563 but were made public during the pestilence only.

Whatever may have been the first year of the bills, and however early their first publication, they were regularly made out by the Parish Clerks for more than two centuries after 1603. In 1849 they ceased, being practically superseded by the new bills issued, since 1840, under the authority of the Registrar-General.
