From these sources it is known that 837 live births and 16 stillbirths occurred in 1950. They were distributed as shown in the following table:—

Ward.	Live Births.	Birth Rate per 1,000 Population.	Stillbirths.	Stillbirth Rate per 1,000 total births.

Page 10

The proportion of institutional births at 75 per cent. of the total is much the highest yet recorded in the district and is twice what it was ten years ago and three times that of fifteen years ago. This increasing tendency to institutional confinements is shown by the following percentages since 1935:—
