under review is very much more correct than the estimated
population of 1907.
For 1908, the number of occupied houses was not
available, and the population has been calculated upon the
assumption that the increase in the population maintained the
same rate of progression each year as it did during the
intercensal period, 1891-1901. The population thus obtained,
156,627, compared with 152,532 for 1907, shows an increase in
one year of 4,095 persons. The increase in the population by
natural increment, i.e., the excess of births over deaths,
amounted to 1,774. It may be assumed, therefore, that the
difference of 2,321 between the total estimated increase and
that shown by the natural increment is due to immigration into
the district.
In order to make the statistical returns in this report
comparable with other districts and with the Returns of the
Registrar-General, a period of 53 weeks ended January
2nd, 1909, has been taken. All mortality statistics contained
in the report are based upon the figures recorded during this
period.
The various rates are per 1,000 persons estimated to be
living in either Ward, Division or whole Borough, except where
otherwise stated.
The death rates calculated for the wards Brockley,
Catford and Forest Hill, are, in all probability, somewhat
higher than they should really be. When the next census is
taken it will probably be found that the population of these
Wards has increased more in proportion than during the last
intercensal period, owing to the very large building operations
which have taken place during recent years.
