218 RELATION OF ORIGIN TO FERTILITY AND INFANT MORTALITY
INFANT MORTALITY
Attention is now called to another important section of vital statistics, that of infant
mortality. The numbers of births and deaths of children under one ‘year are tabulated by
the origin of the father, and the data for the registration area for the year 1925 appear in
Table 135. The number of infant deaths is shown as a percentage of the total births in
Column three, thus giving the crude infant mortality rate for each origin, The figures
for the French include only those of French origin in parts of Canada outside the
province of Quebec.
The usual practice has been followed in computing the infant mortality rates, namely,
that of expressing the number of deaths of infants under twelve months in a given calendar
year as a percentage of the number of births in the same year. In doing that, however,
certain assumptions are made which may be mentioned in passing. First, a large percentage
of infant deaths occurring in the given year consist of those who have been born some
time during the previous twelve months. For instance, of the 12,169 infants less than one
year of age who died in 1925 perhaps half were born in 1924, yet the total infant deaths
in 1925 is expressed as a percentage of the total births in that calendar year, The assumption
underlying this procedure is that no great error appears in the infant mortality rates
as a result of using the 1925 figures of births as a basis with which to compare the deaths
in that period. A slight error is involved, of course, and it might assume considerable
dimensions if, for some reason, the birth rate was very much higher or lower in the later
year. Under normal conditions, however, the error is negligible, and as the above is the
most practical method of securing a rate it is usually followed.
The second assumption is that as many children under one year of age came into the
Dominion as left it in the period examined. The influence of any probable difference
setween the number of infants under one year emigrating and immigrating can, in the
nature of the case, be only very slight. So for all practical purposes it is correct to follow
the universal procedure and to say that approximately 8.07 out of every 100 babies born
in the registration area of Canada die before living twelve months.
