Taken altogether, the increased population is sufficient
to account for the above numbers.
Births.—For the first time, thanks to the wise
liberality of the Board, an accurate record of the births
registered in the Eastern Division of Battersea, has been
furnished by the Registrar, and this is especially valuable
on the present occasion, as a reliable test of the real
population.
It is evident that, in a given number of people of all
ages, a certain number of births will occur in each year,
and scarcely vary from one year to another, if the population
be to a great extent identical, and of the same class.
It has been shewn in former reports that the birth-rate
of Battersea remains at 42 per thousand with remarkable
steadiness, and as the births of 824 males, and 732 females,
in all 1556, during 1874 in East Battersea in an officially
estimated population of 33,085, gives a birth-rate of 47
per thousand, one of two things is evident, either that the
population is much larger, or 5 additional births per thousand
living persons have occurred in the year, a proposition
which cannot be for a moment entertained.
If the normal birth-rate of 42 per thousand be
adopted, there results a mean population for 1874 in East
Battersea, of 37,023, which is probably very nearly the
true number.
Vaccination.—The Register of the Public Yaccinator
gives the following cases successfully operated upon during
