Attack Rates represent the number of cases occurring to
every 1,000 persons living at all ages. These rates are useful
for comparison with other Boroughs in regard to the incidence of
infectious diseases.
The attack rate from all infectious diseases (excluding
Puerperal Fever) during the year amounted to 6.13 per 1,000
of the population, compared with 511 in 1911, and 5.12 in
1910. The attack rate for the County of London was 5.24,
compared with 5.31 in 1911.
The attack rates for the Wards will be found on page
33. It will be seen that Catford Ward had the largest
number of cases in proportion to its population, having an
attack rate of 7.63 per 1,000. The lowest attack rate was
in Forest Hill Ward, 4.40 per 1,000.
