3. The housing were A.D. 1671 but 3,850, which if they had
increased A.D. 1682 but according to the burials, they had been but
5,143, or, according to the hearths, had been but 5,488, whereas
they appear 6,025, increasing double to the hearths. So as it is
likely there hath been some error in the said account of the
housing, unless the new housing be very small, and have but one
chimney apiece, and that one-fourth part of them are untenanted. On
the other hand, it is more likely that when 1,696 died per annum
there were near 6,000; for 6,000 houses at 8 inhabitants per house,
would make the number of the people to be 48,000, and the number of
1,696 that died according to the rule of one out of 30, would have
made the number of inhabitants about 50,000: for which reason I
continue to believe there was some error in the account of 3,850
houses as aforesaid, and the rather because there is no ground from
experience to think that in eleven years the houses in Dublin have
increased from 3,850 to 6,025.

Moreover, I rather think that the number of 6,025 is yet short,
because that number at 8 heads per house makes the inhabitants to be
but 48,200; whereas the 2,263 who died in the year 1682, according
to the aforementioned rule of one dying out of 30 makes the number
of people to be 67,890, the medium betwixt which number and 48,200
is 58,045, which is the best estimate I can make of that matter,
which I hope authority will ere long rectify, by direct and exact
inquiries.

4. As to the births, we say that A.D. 1640, 1641, and 1642, at
London, just before the troubles in religion began, the births were
five-sixths of the burials, by reason I suppose of the greaterness
of families in London above the country, and the fewer breeders, and
