This report presents national estimates of fertility, family planning, and reproductive health indicators among females 15-44 years of age in the United States in 2002 from Cycle 6 of the National Survey of Family Growth (NSFG). For selected indicators, data are also compared with earlier cycles of the NSFG.
Descriptive tables of numbers and percentages are presented and interpreted. Data were collected through in-person interviews of the household population 15-44 years of age in the United States between March 2002 and March 2003. The sample included 7,643 females and 4,928 males, and this report focuses on data from the female sample. The overall response rate for the Cycle 6 NSFG was 79 percent, and the response rate for women was 80 percent.
Given the range of topics covered in the report, only selected findings are listed here. About 14 percent of recent births to women 15-44 years of age in 2002 were unwanted at time of conception, an increase from the 9 percent seen for recent births in 1995. Among recent births, 64 percent occurred within marriage, 14 percent within cohabiting unions, and 21 percent to women who were neither married nor cohabiting. The overall rate of breastfeeding initiation among recent births increased from 55 to 67 percent between 1995 and 2002. About 50 percent of women 15-44 had ever cohabited compared with 41 percent of women in the 1995 survey; the percentage of women currently cohabiting also increased, from 7 to 9 percent between 1995 and 2002.
本报告展示了2002年美国国家家庭成长调查（NSFG）第6轮调查中15 - 44岁女性的生育、计划生育及生殖健康指标的全国性估计数据。对于部分选定指标，还将数据与NSFG早期轮次进行了比较。
呈现并解读了数字和百分比的描述性表格。数据通过2002年3月至2003年3月对美国15 - 44岁家庭人口的面对面访谈收集。样本包括7643名女性和4928名男性，本报告聚焦于女性样本数据。NSFG第6轮调查的总体回应率为79%，女性回应率为80%。
鉴于报告涵盖的主题范围广泛，此处仅列出部分选定的调查结果。2002年，15 - 44岁女性近期生育中约14%在受孕时是意外怀孕，高于1995年近期生育中9%的比例。在近期生育中，64%发生在婚内，14%发生在同居关系中，21%发生在既未结婚也未同居的女性中。1995年至2002年期间，近期生育中开始母乳喂养的总体比例从55%增至67%。15 - 44岁女性中约50%曾有过同居经历，而1995年调查中的这一比例为41%；目前正在同居的女性比例也有所增加，从1995年的7%增至2002年的9%。
