... of total population. The results failed to confirm the hope that the crude birth rate would be decreased by 12 per 1,000 in a decade merely by sterilization of five per 1,000 of the population per annum. The study also discusses various measures of reduction in the crude birth rate. By a reasonable measure...

... significant migration loss. In the period 1960–1970 and up to the present fertility has been declining. An important question is what part has this net migration loss of 32,600 had on the reduction of the crude birth rate from 33.6 in 1960 or from 31.5 in 1956 to 20.5 in 1970? Using officially published net...
