This report presents national estimates of the fertility of men and women aged 15-44 years in the United States in 2006-2010 based on the National Survey of Family Growth (NSFG). Data are compared with similar measures for 2002.
Descriptive tables of numbers, percentages, and means are presented and discussed. Data were collected through in-person interviews of a nationally representative sample of the household population aged 15-44 years in the United States between July 2006 and June 2010. The 2006-2010 NSFG sample is comprised of 22,682 respondents including 10,403 men and 12,279 women. The overall response rate for the 2006-2010 NSFG was 77%, 75% for men and 78% for women.
Many of the fertility measures among men and women aged 15-44 based on the 2006-2010 NSFG were generally similar to those reported based on the 2002 NSFG. The mean age at first child's birth for women was 23 and the mean age at first child's birth for men was 25. One-half of first births to women were in their 20s and two-thirds of first births were fathered by men who were in their 20s. On average, women aged 15-44 have 1.3 children as of the time of the interview. By age 40, 85% of women had had a birth, and 76% of men had fathered a child. In 2006-2010, 22% of first births to women occurred within cohabiting unions, up from 12% in 2002. These measures differed by Hispanic origin and race and other demographic characteristics.
本报告基于全国家庭成长调查（NSFG）呈现了2006 - 2010年美国15 - 44岁男性和女性生育情况的全国性估计数据。并将这些数据与2002年的类似指标进行比较。
展示并讨论了包含数量、百分比和均值的描述性表格。数据通过对2006年7月至2010年6月间美国15 - 44岁具有全国代表性的家庭人口样本进行面对面访谈收集。2006 - 2010年NSFG样本由22,682名受访者组成，其中包括10,403名男性和12,279名女性。2006 - 2010年NSFG的总体回应率为77%，男性为75%，女性为78%。
基于2006 - 2010年NSFG得出的15 - 44岁男性和女性的许多生育指标总体上与基于2002年NSFG报告的指标相似。女性生育第一个孩子的平均年龄为23岁，男性生育第一个孩子的平均年龄为25岁。女性的初育中有一半是在20多岁时，三分之二的初育孩子的父亲是20多岁的男性。平均而言，15 - 44岁的女性在接受访谈时育有1.3个孩子。到40岁时，85%的女性生育过孩子，76%的男性成为过孩子的父亲。在2006 - 2010年，女性的初育中有22%发生在同居关系中，高于2002年的12%。这些指标因西班牙裔血统、种族和其他人口特征而有所不同。
