Population Characteristics of Communities A, B, and C. Population dynamics are described by zip code data from the American Community Survey 5-year Estimates (2015–2019). The Social Vulnerability Index (SVI) was provided by the Centers for Disease Control by census tract and averaged for census tracts contained within a zip code. Communities B and C are considered low-SES and vulnerable to most vulnerable (quartile III and IV, respectively).
