Before mid-year there was to be an annual summary of the previous data as well.
The death rate for pre-school children was almost halved during the period and by 1967 was less than 1 per 1000 of the mid-year population.
This was highly variable, with a characteristic trough mid-year and a peak at the turn of the year.
There was no month for death reported for 36 infant deaths and, for these, the mid-year value was assigned.
In 1967, the death rates per 100,000 of the mid-year population were 148-1 for males and 55-8 for females.
The female immigrants who stated that marriage was their reason for migration were used as the numerator and the mid-year population (aged 10 years and over) as the denominator.
Age-specific death rates are conventionally computed each year by the ratio of the deaths at each age within that calendar year and the estimated mid-year population at that age.
Increased exports and capital repatriation, as well as a mid-year international lending package, helped the central bank rebuild its international reserves, which increased by almost $7 billion in 1987.
