目标
本报告介绍了美国非婚生育的趋势和变化，并包括导致最近变化的因素的信息。1940- 1999年的数据重点是1990年代的趋势。
方法
本报告中的数据是关于非婚生育的各种衡量标准，包括未婚妇女生育的数量、比率和百分比。大部分数据来自国家生命统计系统。解释所示趋势的其他数据来自全国家庭增长调查、美国人口普查局和其他全国性调查。数据主要以图表和相关表格的形式提供和解释。
结果
在经历了1940 - 1990年的半个世纪的急剧上升之后，非婚生育在20世纪90年代趋于平稳，或者说增长速度放缓。许多因素有助于长期的变化，以及最近的趋势进行了说明。这些变化包括婚姻模式、性活动、避孕药具的使用和堕胎。美国的经验与其他工业化国家的非婚生育数据相结合。结合目前的人口和出生模式，审议了未来非婚生育的可能趋势。
OBJECTIVES
This report presents information on trends and variations in nonmarital childbearing in the United States and includes information on the factors that have contributed to the recent changes. Data are presented for 1940-99 with emphasis on the trends in the 1990's.
METHODS
Data in this report are presented on a variety of measures of nonmarital childbearing, including numbers, rates, and percent of births to unmarried women. Most of the data is from the National Vital Statistics System. Additional data explaining the trends shown are from the National Survey of Family Growth, the U.S. Census Bureau, and other national surveys. Data are presented and interpreted principally in charts and related tables.
RESULTS
After rising dramatically during the half century from 1940 to 1990, out-of-wedlock childbearing leveled off, or slowed its rate of increase, in the 1990's. Many factors contributing to the long-term changes as well as more recent trends are described. These include changes in marriage patterns, sexual activity, contraceptive use, and abortion. The experience of the United States is put into context with data on nonmarital childbearing for other industrialized countries. Possible future trends in out-of-wedlock births are considered in the context of current population and birth patterns.
