(a) Rate per 1,000 total births. (b) Comparable figures not available for this period. (c) Cases relate to last quarter only— Rates are adjusted
on an annual basis. (d) Cases relate to last 22 weeks only— Rates are adjusted on an annual basis. (e) In order to preserve uniformity with
published national figures the recently instituted practice of the Registrar.General has been followed in producing this table, namely in taking full
account of any known changes in diagnosis after the receipt of the original notification. These corrections were not available prior to 1944, and
for 1931.43 uncorrected figures are given, but on the basis of dual records kept from 1944-47, comparable figures can be obtained by multiplying
the uncorrected notifications by the following factors:— Cerebrospinal fever 0.730, Diphtheria 0.599, Dysentery 0.908, Encephalitis lethargica 0.545,
Enteric fever 0.721, Erysipelas 0 977, Measles 1.001, Ophthalmia neonatorum 1004, Pneumonia 0 964, Poliomyelitis and polioencephalitis 0.845,
Puerperal fever 0.840, Puerperal pyrexia 1.002, Scarlet fever 0.950, and Whooping cough 1.002. Correction factors are not available for malaria and
scabies and in these two diseases the corrected figure of notifications is given for 1947 only. (f) Rate per 1,000 live births.
