Born 24 Apr 1620; died 18 Apr 1674 at age 53.

#English #statistician who is considered by many historians to have founded the science of #Demography (statistical study of human #populations).

For his published #analysis of the parish #records of christenings and #deaths, he was made a charter member of the #RoyalSociety.

His 90-page book, “Natural and Political Observations Mentioned in a Following #Index, and Made upon the Bills of #Mortality” was distributed at the Royal Society meeting on 5 Feb 1662.

He described his work as having “reduced several great confused volumes” of parish records into a few easily to understood #tables, and “abridged such Observations... into a few succinct #Paragraphs.” He initiated “life tables” of life #expectancy.

His use of #demographics was further pioneered by his friend Sir William Petty and Edmond Halley, the Astronomer Royal.
