Abstract

The perfect contraceptive population is a model in which couples can avoid having more children than they wish and can have children only with determined spacing. In the U.S. from 1960 to 1965 4.7 million births 20% of total births were unwanted and would AVE been prevented with perfect contraception. About 2 million of the unwanted births occurred among the poor and near-poor; 1/2 of these being Negro poor and near-poor. For the same years 2/5 of wanted births would have occurred later if their timing had been controlled. The elimination of unwanted births would cause a reduced growth rate in the U.S. barring an increase in the average number of children desired. Even if cohort replacement were achieved a zero growth rate for the nation would be achieved only after more than 60 years.
