MORTALITY IN CHILDHOOD. 43
MORTALITY IN CHILDHOOD.
By "childhood" is here meant the age-group 0-5 years. The mortality rates observed
among males and during the past year are compared with those for 1913 and the
averages for 1909-13 in Table 10 (page 11). The rate among males was 36.87 per 1,000
estimated living during 1914, as compared with 42.33 in 1913, and an average of 43.03 for
the five years 1909-13. Among females the mortality was at the rate of 28.55 last year, as
compared with a rate of 37 02 in 1913, and an average of 35 01.
Mortality at Ages under One Year.
Infantile Mortality.
Owing to the changes which have been introduced within recent years in the methods of
correcting the returns of births and deaths, it is necessary, with a view to the preservation of the
continuity of the records, to submit three rates of infantile mortality, viz.:—
Crude rates, based on the numbers of births and deaths registered locally without any
corrections for births or deaths of non-residents within the Borough, or for the like belonging to
the Borough but occurring in outlying areas ;
Netl rates, derived from the births corrected by the exclusion of children born to nonresident
parents, and the deaths corrected by the exclusion of those of non-residents, and the
inclusion of those of residents of the Borough taking place in outlying metropolitan districts; and
Corrected rates, calculated from births and deaths completely corrected for transfers (births
and deaths) both outwards and inwards.
Last year 293 deaths at ages under one year were registered within the Borough, including
48 of non-resident children. In 1913 the corresponding numbers were 342 and 66 respectively.
The crude rate of infantile mortality was 115 per 1,000 births for the whole year, ranging from a
minimum of 71 in the second quarter to a maximum of 133 in the third.

Crude.
Quarters 1. 2. 3. 4. Year.
1914 111 71 133 121 115
1913 155 83 107 140 120
1909-13 133 100 122 141 124
The nett mortality per 1,000 births for the whole year was 106, or 3 per 1,000 less than the
rate recorded in 1913. (See below.)

1913 130 67 109 128 109
1909-13 120 93 114 128 114
The corrected rate for the year was 96 per 1,000 births, as compared with 101 in 1913, and
an average of 106. (Table 30.) The rates for both sexes were below those observed in 1913
and in the five years 1909-13. The actual number of deaths at ages under one year will be
found in Table II., Appendix, and the causes of death (at each month of life, distinguishing the
sexes) in Table X.
The rate of mortality for the whole county, deduced from data given in the Quarterly
Reports of the Registrar-General, was 102 per 1,000 births last year, or 2 per 1,000 less than the
rate recorded in 1913, and 4 per 1,000 less than the average. The corresponding rates for the
districts circumjacent to the Borough are given on the next page.
