There has been an explosion in contraceptive use in the past 30 years. In 1960-65, the level of contraceptive use in the developing countries of Asia, Latin America and Africa represented about 9% of married couples of reproductive age. In the 1990s use of contraception in developing countries comprises over 50% of couples and contraceptive prevalence is increasing each year. Total fertility rates for the developing world have already fallen from over 6, where they were in 1960 to about 4, halfway toward the replacement level of 2.1. The United Nations projects that during this decade, over 90 million people will be added each year to world population. If this projection is not to be exceeded, prodigious supplies of contraceptives will have to be available at affordable cost to the people of developing countries, where 94% of this population increase will occur. New technology alone will not guarantee this success, but it would help ensure that people are able to meet their fertility objectives.
在过去30年里，避孕措施的使用急剧增加。1960 - 1965年，亚洲、拉丁美洲和非洲发展中国家的避孕措施使用率约为育龄已婚夫妇的9%。20世纪90年代，发展中国家的避孕措施使用率超过了50%，而且避孕普及率每年都在上升。发展中世界的总生育率已从1960年的超过6降至约4，距更替水平2.1已近一半。联合国预计，在这十年中，世界人口每年将增加9000多万。若要不超过这一预测，就必须以可承受的成本为发展中国家的民众提供大量避孕用品，因为新增人口的94%将出现在这些国家。仅靠新技术无法确保成功，但它将有助于确保人们能够实现其生育目标。
