REPORT
OF THE
Medical Officer of Health
FOR THE YEAR 1906.
VITAL STATISTICS.
The Vital Statistics set out in the Report are based upon
the population of the entire Borough estimated to the middle of
the year 1906, which amounted to 148,463, compared with
144,420 for 1905, an increase in one year of 4,043 persons.
The increase in the population by natural increment, i.e., the
excess of births over deaths, amounted to 1,558. It may be
assumed, therefore, that the difference of 2,485 between the
estimated population 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 52 weeks ending December 29th,
1906, is 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 the Ward, Division, or whole Borough, except
where otherwise stated.
