... 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...

Such exponential-model rates form the basis for computation of a fecundity decrement table presented in this paper. Sterility proportions from the table are compared to some empirical data...

... reveals a high regional variation in birth rate: from 20 per 1,000 (Bas Uele) to 60 per 1,000 (Kivu). This variation is consistent with the variation in sterility level as evidenced by the proportion of women never having had a live birth. The proportion of childlessness varies from 5 percent (Kivu...

Thus, when combining pill-IUD users with women protected by sterilization to derive an unwanted fer- tility rate for women using PAC, and when calculating the rate when com- bining those using and those not using PAC, it was necessary to adjust for those differences. That was done...
