The infant mortality rate is often used as a measure of a country’s health because similar factors influence population health and infant mortality (1). Although infant mortality has declined in the United States, disparities still exist across geographic areas and demographic groups (2–4). Urbanization level, based on the number and concentration of people in a county, can impact health outcomes (3–9). Previous research indicates that infant mortality rates vary by urbanization level and also by maternal and infant characteristics (3–9). This report describes differences in infant mortality among rural, small and medium urban, and large urban counties in the United States by infant’s age at death, mother’s age, and race and Hispanic origin in 2014.
婴儿死亡率常被用作衡量一个国家健康状况的指标，因为类似的因素会影响人口健康和婴儿死亡率(1)。尽管美国的婴儿死亡率有所下降，但不同地理区域和人口群体之间仍存在差异(2 - 4)。基于一个县的人口数量和集中度的城市化水平会影响健康结果(3 - 9)。先前的研究表明，婴儿死亡率因城市化水平以及母婴特征而异(3 - 9)。本报告描述了2014年美国农村、中小城市和大城市县在婴儿死亡年龄、母亲年龄以及种族和西班牙裔血统方面的婴儿死亡率差异。
