in order to institute a fair comparison between one district
and another, it is necessary to further correct the death-rate
for sex and age distribution, for it is obvious that a population,
containing a large number of young persons between the ages
of five and thirty, when the death-rate is very low, should
have a lower death-rate, than one containing an excess of
aged persons. The population of London is taken as the
standard, and factors are calculated which when multiplied
by the death-rate of any Metropolitan Borough, give the
death-rate that Borough would have if the age distribution
of its population were the same as in the Metropolis. The,
factor for the correction of the Woolwich death-rate is 1-0249.
11. The net deaths were 1,580, and the net death-rate
12.3, compared with 12.8 and 11 5 in the two preceding
years, and 12.7 the average of the ten preceding years.
12. By multiplying by 1.0249, the factor for age distribution,
we get the corrected death-rate, viz., 12.6, which
rate should be used in comparing Woolwich with other places
in which the death-rate is similarly corrected. The following
table shows the net and corrected death-rates of Woolwich, oompared with London and the adjoining Boroughs:—
Net. | Standard. | |
---|---|---|
England and Wales | 13.7 | 13.4 |
95 Great Towns | 14.3 | 14.7 |
London | 14.2 | 14.2 |
Greenwich | 14.2 | 14.0 |
Lewisham | 10.6 | 10.4 |
West Ham | 14.5 | - |
East Ham | 10.0 | - |
Erith | 9.9 | - |
12.3 | 12.6 |
