这一章描述了从1890年到现在避孕实践和生育率的上升。确定了两个主要阶段：第一个阶段仅限于欧洲人口，涉及效率低的方法，第二个阶段涉及整个地球，涉及现代方法。今天，撒哈拉以南非洲是唯一一个避孕药具使用率低、生育率高的地区。然而，全世界近一半的怀孕仍然是意外怀孕，在避孕保护方面仍有很大的改进余地。主要的国际优先事项是非洲，那里的人口因素危及减少贫穷和饥饿的目标。(C) 2008 Elsevier Ltd版权所有。
This chapter describes the rise in contraceptive practice and fill in fertility from around 1890 to the present day. Two main phases are identified: the first confined to European populations and involving methods of low efficacy, and the second embracing the whole planet involving modern methods. Today, SUb-Saharan Africa is the only region where low levels of contraceptive use and high fertility persist. Nevertheless, nearly half of pregnancies worldwide are Still unintended, and much scope remains for improvement in contraceptive protection. The main international priority is Affica, where demographic factors jeopardize the goals of reducing poverty and hunger. (C) 2008 Elsevier Ltd. All rights reserved.
