1980～1981年期间,全世界有5千万以上的妇女应用口服避孕药。其中有一半以上是通过处方或无处方从医药商店或其它商店购得。其余,包括大约7百万中国妇女是由政府或各个部门计划供应。在发达国家,几乎全部服药者是购买口服避孕药。1975年出售达到高峰,大约为2亿8千7百万周期,到1979年降为2亿5千3百万周期。此后,稳定在这个水平。出售下降主要发生在美国。相反,1975年以来,拉丁美洲的许多国家大约增加了50%的销售量。其它发展中地区全部由公共和个人计划供应,但所占比数较小。从美国国际开发署
Between 1980 and 1981, more than 50 million women worldwide used oral contraceptives. More than half of them are purchased from pharmacies or other stores by prescription or without prescription. The rest, including about 7 million Chinese women, is planned by the government or various departments. In developed countries, almost all those who take the pill purchase oral contraceptives. Sales peaked in 1975, at around 287 million cycles, and by 1979 dropped to 253 million cycles. Since then, stabilized at this level. The decline in sales mainly occurred in the United States. On the contrary, many countries in Latin America have seen an increase of about 50% in sales since 1975. Other developing regions are all supplied by public and private programs but in smaller proportions. From the U.S. Agency for International Development
