The population of the Colony fluctuates so much that it is not possible to obtain accurate figures to show the age distribution of The population.
The census return of 1921 however gives tables showing the ages of 503,686 Chinese inhabiting the island of Hongkong and the Kowloon peninsula and the floating population connected therewith.
On classifying this population by age groups the following percentages of the population are found in each such groups :—
Under 1 year
2-22 per cent
Over 1 year and under 5 years 5'94 per cent Over 5 years and under 15 years 16-10 per cent
Over 15 years and under 25 years 25·10 per cent į 63-78 per Over 25 years and under 45 years 37'60 per cent ƒ cent. Over 45 years and under 60 years 10-20 per cent Over 60 years
2:50 per cent
On the Chinese deaths from Tubercular diseases for 1922 being analysed according to certain disease groups and. their percentage rates for each of the above age groups ascertained, the following table results and, if it be assumed that the : Pe distribution of the 1922 Chinese population is similar to that given above, a comparison may be made between the various types of tubercular disease in the different age groups and the incidence of each type in each age group,
For the purpose of this table tubercular diseases have been grouped as follows :-
Type 1. Pulmonary and Acute Miliary Tuberculosis.
