The purpose of this study is to summarize publicly available and relevant COVID-19 data sources, to address the benchmarking challenge from the data heterogeneity through clustering, and to classify counties J o u r n a l P r e -p r o o f based on their underlying variations. Particularly at the county-level, previous studies have implemented clustering techniques to analyze various data sources relating J o u r n a l P r e -p r o o f to demographic, geographic, environment, and socioeconomic determinants of health and disease. While previous findings reveal possible geographical clusters of COVID-19 cases at the county-level, our study indicates this is from the underlying typology based on high-dimensional variables. ./cache/cord-287027-ahoo6j3o.txt ./txt/cord-287027-ahoo6j3o.txt
