(a) Kate per 1,000 total births. (6) Comparable figures not available for this period, (c) Oases relate to last quarter only — Rates are adjusted on an annual
basis, (d) Cases relate to last 22 weeks only—Rates are adjusted on au 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 bv the following factors:—Cerebro.spinal fever (Meningococcal
lufection) 0.730, Diphtheria 0.599, Dysentery 0.908, Encephalitis lethargica 0.545, Enteric fever 0.721, Erysipelas 0.977, Measles 1.001, Ophthalmia neonatorum
1.004, Pneumonia 0.964. Poliomyelitis including polioencephalitis 0.845, 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. (/) Rate per 1,000 live births.
iff) Up to 1949 the figures relate to encephalitis lethargica.
