Geographic distribution of CA-Sa SSTI rates presenting in emergency departments in California between 2016-2019. Panels are as follows: a infection rates per 10,000 residents using the originally reported patient ZIP code (proxied by ZIP code tabulation area) as the geographic analysis unit (n = 1,769); b infection rates per 10,000 residents using randomly assigned census tracts based on residential density within patient ZIP codes as the geographic analysis unit (n=7,984); and c infection rates per 10,000 residents using the crosswalked Medical Service Study Area as the geographic analysis unit (n=542). Geographies where the estimated population was less than 20 residents have been suppressed. All variables were classified using natural breaks
