To determine the number of women aged 15 to 44 years with impaired fecundity every 5 years from 1995 to 2020.
Data are used from cycle IV of the National Survey of Family Growth conducted by the National Center for Health Statistics. Population projections prepared by the U.S. Census Bureau are used for the expected population base for 1995 to 2020. Prospective demographic projection analysis is used to estimate the number of women with impaired fecundity.
The National Survey of Family Growth interviewed 8,450 women aged 15 to 44 years as of March 15, 1988.
Number of women with impaired fecundity.
The number of women with impaired fecundity may drop from 5.1 million in 1995 to 4.7 million in 2015 and then rise to 4.8 to 5.9 million in 2020.
The age structure of the population will cause the absolute number of women with impaired fecundity in the United States to increase slowly, if at all, over the next 25 years.
确定1995年至2020年期间每5年15至44岁生育力受损女性的数量。
使用美国国家卫生统计中心进行的第四次全国家庭成长调查的数据。美国人口普查局编制的人口预测用于1995年至2020年的预期人口基数。前瞻性人口预测分析用于估计生育力受损女性的数量。
全国家庭成长调查于1988年3月15日对8450名15至44岁的女性进行了访谈。
生育力受损女性的数量。
生育力受损女性的数量可能从1995年的510万下降到2015年的470万，然后在2020年上升到480万至590万。
人口年龄结构将导致美国生育力受损女性的绝对数量在未来25年中即使增加也将缓慢增长。
