This paper considers the relationship between economic conditions and health with a focus on different approaches to geographic aggregation. After reviewing the tradeoffs associated with more- and less-disaggregated analyses, I update earlier state-level analyses of mortality and infant health and then consider how the estimated effects vary when the analysis is conducted at differing levels of geographic aggregation. This analysis reveals that the results are sensitive to the level of geographic aggregation with more-disaggregated analyses-particularly county-level analyses-routinely producing estimates that are smaller in magnitude. Further analyses suggest this is due to spillover effects of economic conditions on health outcomes across counties.
本文探讨经济状况与健康之间的关系，重点关注地理聚合的不同方法。在回顾了与更细化和更粗化分析相关的权衡之后，我更新了早期对死亡率和婴儿健康的州级分析，然后考虑当在不同地理聚合水平上进行分析时，估计效应如何变化。该分析表明，结果对地理聚合水平敏感，更细化的分析——尤其是县级分析——通常会得出量级较小的估计值。进一步的分析表明，这是由于经济状况对各县健康结果的溢出效应所致。
