SOME COMPARISONS BETWEEN THE YEAR 1921 AND 1922.
For the purpose of calculating the weekly and monthly death rates throughout the year the population of the Colony (excluding the New Territories which are without the jurisdiction of the Board) for 1921 was estimated to be 585,880 and for 1922 578,200.
This decrease for 1922 is due to a census having been taken in 1921. The census returns were much lower than was anticipated and were admitted to be probably lower than they should have been by the census officer.
The estimated population for 1922 was based on these census returns.
The total number of deaths registered in 1921 was 11,880 and in 1922 14,569.
The general death rate for 1921 was 20.27 and for 1922 25.16 giving a difference of 4.89 per 1,000.
This difference in the death rates suggests at first that the health of the Colony was much worse than in the previous year.
The excess of deaths in 1922 over those in 1921 was 2,689.
The deaths from Notifiable Diseases in 1921 were 484 and in 1922 1,416 (1,071 from Plague alone) giving an excess for 1922 of 932 deaths.
By subtracting this last figure from the total excess deaths it is seen that there were in 1922 1,757 excess deaths in 1922 to be accounted for by other causes than the Notifiable Infectious Diseases.
The deaths from Respiratory Disease, Tuberculosis, Malaria and Beri-beri, for the two years were as follows:-
1921 1922 Respiratory Diseases (excluding Tubercular Disease) 3,832 4,863 Tuberculosis 1,894 2,096 Malaria 332 454 Beri-beri 526 829 6,584 8,242With regard to the increase in deaths from Malaria: this may perhaps be explained in part by the rapid growth of urban areas and the consequent extension of the population into districts in which permanent anti-malarial measures have not kept pace with the growth of the population.
