London Bills of Mortality

For generations, weekly printed bills counted burials and christenings across London parishes, listing reported causes of death and making the city's mortality visible as recurring numbers.

The bills did not merely record an epidemic from outside. Parish boundaries, household reports, searchers' judgements, cause labels, printing, and omission actively constructed the population they appeared to count.

Reading the source

A weekly total is the end of a chain of decisions.

Nearly 8,000 weekly bills were published between 1603 and 1752. Repetition made comparison possible, but the categories and area covered did not remain fixed.

A surviving bill should therefore be read both vertically and across time. One issue reveals how deaths were distributed among parishes and causes during a particular week; a sequence reveals seasonality, outbreaks, altered boundaries, and changes in classification. Apparent precision does not remove uncertainty. It makes the administrative process behind each number more important to reconstruct.

Parishes make mortality geographical

Burials were grouped by parish, allowing readers to compare places and follow increases associated with plague. The printed city was nevertheless bounded by which parishes reported and how metropolitan space was defined.

Causes preserve historical classification

Labels such as plague, consumption, childbed, teeth, aged, and fever record contemporary acts of naming. They should not be translated automatically into modern diagnoses or treated as stable categories across the whole series.

Regular publication creates reusable data

Readers could compare weeks and years, while John Graunt's 1662 analysis used accumulated bills to reason about population and mortality patterns. Later statistical value emerged from records designed for earlier civic purposes.

Production and limits

The people counted are visible unevenly.

Information moved from households and burial practices through parish clerks and searchers—often older women who inspected bodies—before reaching a printed table. Their skilled but poorly rewarded work is easily hidden by the apparent impersonality of numbers.

The bills count reported burials rather than every death in a modern civil-registration system. Religious affiliation, movement, poverty, place of burial, disputed cause, and administrative boundaries could all affect whether and how someone appeared.

Digitisation enables computation across millions of entries, but transcription introduces another interpretive layer. Researchers must preserve original wording, changing layouts, uncertain readings, and missing issues rather than treating the dataset as complete.
