Annual Report of the London County Council, 1911.

The factors for correction, also shown in the table, have been calculated by applying the1901census population at each age and for each sex of each of the London sanitary districts to the death-rates at each age and for each sex obtaining for London in the five years1897-1901 :—

Phthisis.
The deaths from phthisis, fully corrected for institutions, in the Administrative County of
London during 1911 (52 weeks) numbered 6,084, including acute miliary tuberculosis.

The distribution of deaths(a)from influenza throughout the year(b)for each of the years 1890 to 1911 is shown in the following table:—

The phthisis death-rate since 1850 (corrected (e) for differences in the age constitution of the
population) in relation to the mean death-rate of the period 1851-1911 (males and females) is shown
in diagram (W).
This diagram shows the marked decline of phthisis mortality in both sexes, the greater incidence
of such mortality on males than on females, and the fact that until recent years the decline has been
more manifest in females than in males. The figures for 1911 (d) are more fully corrected (c) than those
for previous years, and the increased incidence of phthisis in this year may be partly or wholly accounted
for by this fact.

The death-rates from this disease in successive periods have been as follows :—

Period.Denth-rate per 1,000 persons living.Period.Death-rate per 1,000 persons living.
