title: Aggregation and the estimated effects of economic conditions on health.
abstract: 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.
