Phthisis.
The deaths from phthisis, fully corrected for institutions, in the Administrative County of
London during 1912 (52 weeks) numbered 6,069, including acute miliary tuberculosis, as compared
with 6,084 in 1911 (52 weeks.
Phthisis
death-rates,
London,
1851-1912.
The death-rates from this disease in successive periods have been as follows:-
Period. | Death-rate per 1,000 persons living. | Period. | Death-rate per 1,000 persons living. |
---|---|---|---|
1851-1860 | 2.86 | 1904 | 1.67c |
1861-1870 | 2.84 | 1905 | 1.45c |
1871-1880 | 2.51 | 1906 | 1.50c |
1881-1890 | 2.08 | 1907 | 1.46c |
1891-1900 | 1.79c | 1908 | l.39c |
1901-1910 | 1.49c | 1909 | 1.40c |
1910 | 1.25c | ||
1901 | 1.65c | 1911 | |
1902 | 1.61.c | 1912 | |
1903 | 1.57c |
The phthisis death-rate since 1850 (corrected for differences in the age constitution of the
population) in relation to the mean death-rate of the period 1851-1912 (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. Since the year 1910 the deaths from phthisis have been more
fully corrected (d) than in previous years, and the increased incidence of phthisis shown in the last two
years may be partly or wholly accounted for by this fact.
Phthisis
death-rates
in London
boroughs.
The following table shows the crude phthisis death-rate ; and the rate corrected for differences in the age and sex constitution of the population of the various sanitary districts. The factors for correction, also shown in the table, have been calculated by applying the 1911 census 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 in England and Wales during the decennium 1901-1910:-
