NCHS Data Brief. 2017 Jan(297):1-8.
In 2010, one-fifth of the U.S. population lived in rural areas (1). There is known variation in social, demographic, and health characteristics across urban and rural residence (1–3). Recent National Center for Health Statistics (NCHS) reports show higher teen birth and infant mortality rates in rural counties than in urban counties (4,5). Less is known about urban and rural variation in fertility-related behavior, such as sexual activity and contraceptive use. Using National Survey of Family Growth (NSFG) data from 2011 through 2015 for women aged 18–44, this report describes urban-rural differences in first sexual intercourse, marital and cohabitation status, number of births, and contraceptive use based on residence at the time of interview.
2010年，五分之一的美国人口居住在农村地区（1）。城市和农村居民在社会、人口和健康特征方面存在已知差异（1 - 3）。美国国家卫生统计中心（NCHS）最近的报告显示，农村县的青少年生育率和婴儿死亡率高于城市县（4,5）。关于生育相关行为（如性行为和避孕措施使用）的城乡差异，人们了解得较少。本报告利用2011年至2015年针对18 - 44岁女性的全国家庭成长调查（NSFG）数据，描述了首次性行为、婚姻和同居状况、生育数量以及基于访谈时居住地的避孕措施使用方面的城乡差异。
