100,000 population. For London 101.7 and 21 respectively.
In the subjoined table the rates are set out from 1881.

It is suggested that the lowness of the death-rate in the last two years
is to be accounted for by the heavy toll taken by influenza in 1919, but
allowance ought to be made in 1917 and 1918 for the great increase in the
population in Westminster in these years, when there was an influx of
war workers. The averages of 5 yearly periods show a continuous reduction
in the pulmonary rate in each period during the last 40 years, the rate
in the last 5 years being 35 per cent, less than in the 10 years 1881-90.
The average rate in the last 20 years is 28 per cent, less than in the former.
The periodjshowing the greatest [reduction] was the five years 1906-10.
In the non-pulmonary deaths, the reduction has been very considerable
in the last 20 years, viz., from 70 to 20 per 100,000.
The death-rates from all forms of tuberculosis per 100,000 of population
