3. During the year 2,975,258 persons entered and 2,827,449 persons left the Colony, making a daily average of 8,129 arrivals and 7,728 departures. The daily average for 1931 was 7,094 arrivals and 7,660 departures.
4. Registration of Births and Deaths is the rule in the urban districts but in the New Territories generally registration has not been enforced; therefore, in computing birth rates and death rates the population of the New Territories should not be taken into account.
5. The number of births registered was:-
Chinese Non-Chinese 13,166 4316. The deaths registered among the civil population number 19,829 giving a crude death rate of 24.74 per mille as compared with 24.08 for the previous year.
Deaths. Estimated Population, Death rate per mille population. Chinese 19,546 791,036 24.72 Non-Chinese 283 19,984 14.167. The number of deaths of infants under one year was Chinese 6,916, non-Chinese 38. If the figures for Chinese births represented the total births, which they do not, the infantile mortality figure for the Chinese would be 525.28 as compared with 617.42 in the previous year. The infantile mortality figure among non-Chinese was 88.17 as compared with 61.85 in 1931.

## PUBLIC HEALTH
1. In the absence of some general system of registration of sickness, the only sources of information available for gauging the state of the public health in this Colony are the returns relating to deaths, the notifications of infectious diseases and the records of hospitals. Judging from the death returns the health of the Colony was not quite so good as in the previous year. The crude death rate was 24.74 per mille as compared with 24.08 for 1931.
2. Respiratory diseases accounted for 43.05 per cent of the total deaths; the percentage for 1931 was 42.25. The principal diseases causing death were broncho-pneumonia, pulmonary tuberculosis, bronchitis, pneumonia, infantile diarrhoea and diarrhoea.
