Data from the National Vital Statistics System •Birth rates for teenagers aged 15-19 declined in urban and rural counties from 2007 through 2015, with the largest declines in large urban counties and the smallest declines in rural counties. •From 2007 through 2015, the teen birth rate was lowest in large urban counties and highest in rural counties. •Declines in teen birth rates in all urban counties between 2007 and 2015 were largest in Arizona, Massachusetts, Connecticut, Minnesota, and Colorado, with 17 states experiencing a decline of 50% or more. •Declines in teen birth rates in all rural counties between 2007 and 2015 were largest (50% or more) in Colorado and Connecticut. •In 2015, teen birth rates were highest in rural counties and lowest in large urban counties for non-Hispanic white, non-Hispanic black, and Hispanic females. Teen birth rates have demonstrated an unprecedented decline in the United States since 2007 (1). Declines occurred in all states and among all major racial and Hispanic-origin groups, yet disparities by both geography and demographic characteristics persist (2,3). Although teen birth rates and related declines have been described by state, patterns by urban-rural location have not yet been examined. This report describes trends in teen birth rates in urban (metropolitan) and rural (nonmetropolitan) areas in the United States overall and by state from 2007 through 2015 and by race and Hispanic origin for 2015.

2007年至2015年期间，15 - 19岁青少年的出生率在城市和农村县均有所下降，大城市县下降幅度最大，农村县下降幅度最小。
2007年至2015年期间，青少年出生率在大城市县最低，在农村县最高。

2015年，对于非西班牙裔白人、非西班牙裔黑人以及西班牙裔女性而言，农村县的青少年出生率最高，大城市县最低。自2007年以来，美国青少年出生率出现了前所未有的下降（1）。所有州以及所有主要种族和西班牙裔群体的出生率均出现下降，但地理和人口特征方面的差异依然存在（2,3）。尽管已有按州描述青少年出生率及相关下降情况的报道，但城乡地区的模式尚未得到研究。本报告描述了2007年至2015年美国整体及各州城乡（大都市和非大都市）地区青少年出生率的趋势，以及2015年按种族和西班牙裔血统划分的情况。
