We evaluated whether using county-level data to characterize public health measures in cities biases the characterization of city populations. We compared 4 public health and sociodemographic measures in 447 US cities (percent of children living in poverty, percent of non-Hispanic Black population, age-adjusted cardiovascular disease mortality, life expectancy at birth) to the same measures calculated for counties that contain those cities. We found substantial and highly variable city-county differences within and across metrics, which suggests that use of county data to proxy city measures could hamper accurate allocation of public health resources and appreciation of the urgency of public health needs in specific locales.
我们评估了使用县级数据来描述城市的公共卫生措施是否会影响对城市人口的描述。我们将 447 个美国城市的 4 项公共卫生和社会人口学指标（生活在贫困中的儿童比例、非西班牙裔黑人比例、调整年龄后的心血管疾病死亡率、出生时的预期寿命）与计算包含这些城市的县的相同指标进行了比较。我们发现，在不同指标内和之间，城市和县之间存在大量且高度可变的差异，这表明使用县级数据来代表城市措施可能会阻碍公共卫生资源的准确分配，以及对特定地区公共卫生需求紧迫性的认识。
