Data from the National Survey of Family Growth •Among U.S. women aged 15-44 in 2013-2015, 50% expected to have a child in the future. •In 2013-2015, differences were seen by age in women's expectations to have a child in the future, regardless of the number of biological children they have had. •In 2013-2015, women on average expected to have 2.2 children in their lifetime. This estimate has decreased since 2002. •A smaller percentage of never married, not cohabiting women expected to have a child within 2 years from the time of interview (5%) compared with currently married (19%) and currently cohabiting (16%) women. •Eighty-two percent of women who already had two or more children did not expect to have more children in the future. Birth expectations have been shown to be related to sexual activity, contraceptive use, and fertility (1-3). While most U.S. women believe that having two children is ideal (4), this varies by sociodemographic characteristics. Using data from the National Survey of Family Growth (NSFG), this report describes women's birth expectations, number of children expected, and when they expected their next child to be born. Data are shown by age, marital or cohabiting status, and number of children. Selected trends are also shown using NSFG data from 2002, 2006-2010, 2011-2013, and 2013-2015.
美国全国家庭成长调查数据
2013 - 2015年，年龄在15 - 44岁的美国女性中，50%预计未来会生育子女。
2013 - 2015年，无论已生育亲生子女数量多少，不同年龄的女性对未来生育子女的期望存在差异。
2013 - 2015年，女性平均预计一生生育2.2个孩子。自2002年以来，这一估计值有所下降。
与目前已婚（19%）和目前同居（16%）的女性相比，从未结婚、未同居的女性中，预计在接受访谈后两年内生育子女的比例较小（5%）。
已经育有两个或更多子女的女性中，82%预计未来不会再生育更多子女。生育期望已被证明与性活动、避孕措施使用和生育能力有关（1 - 3）。虽然大多数美国女性认为生育两个孩子最为理想（4），但这因社会人口学特征而异。本报告利用美国全国家庭成长调查（NSFG）的数据，描述了女性的生育期望、预期子女数量以及她们预计下一个孩子出生的时间。数据按年龄、婚姻或同居状况以及子女数量进行展示。还利用2002年、2006 - 2010年、2011 - 2013年和2013 - 2015年的NSFG数据呈现了选定的趋势。
