Estimating population
Pioneers were Wrigley & Schofield
1981, used a sample of 404 parishes to calculate aggregate births and deaths
Added births and subtracted deaths to work back from 1871 census
BUT: Needed to multiply up, also issue with migration
Later work with Davies and Oeppen (1997)
Family reconstitution for 26 parishes, building entire family records
Provides more detail about families, but more time-consuming
Use generalised inverse projection (GIP), estimates age-specific rates from counts
From the 1680s to 1720s epi
