Summary

Portrait of William Petty William Petty,  Observations upon the Dublin Bills of Mortality… (1899)

“ The London-Observations reckon eight heads in each Family [11] ; according to which estimation, there are 32000 Souls [12] in the 4000 Families of Dublin; which is but half of what most Men imagine; of which but about one sixth part are able to bear Arms, besides the Royal Regiment.
6. Without the knowledge of the true number of People, as a Principle, the whole scope and use of the keeping Bills of Births and Burials is impaired; wherefore by laborious Conjectures and Calculations to deduce the number of People from the Births and Burials, may be Ingenious, but very preposterous.

“ It is said, that there are Eighty four thousand Houses or Families in London, which is Twenty one times more than are in Dublin; and yet the Births and Burials of London are but Twelve times those of Dublin: which shews that the Inhabitants of Dublin are more crowded and streightned in their Housing, than those of London; and consequently, that to increase the Buildings of Dublin, will make that City more conformable to London. ”

“ I shall also add some Reasons for altering the present forms of the Dublin-Bills of Mortality, according to what hath been here recommended, viz.
1. We give the distinctions of Males and Females in the Births onely; for that the Burials must, at one time or another, be in the same proportion with the Births.||
2. We do in the Weekly and Quarterly Bills propose, that notice be taken in the Burials of what numbers dye above Sixty and Seventy, and what under Sixteen, Six, and Two years old; foreseeing good uses to be made of that distinction.
