Variation in Risk of COVID-19 Infection and Predictors of Social Determinants of Health in Miami–Dade County, Florida


Map A shows the census block groups in Miami-Dade County that have high rates of COVID-19 compared with all other census block groups in the county. Map B is the same map as A but at a larger geographic area of zip codes. This zip code–level map was used to estimate rates at the census block group level because COVID-19 data are only reported at larger geographies, such as zip codes or cities.

Figure 1.

Map A shows estimated census block group level COVID-19 rates per 1,000 population for Miami–Dade County, Florida (generated with areal interpolation) based on zip code level rates.

Maps show rates (by quintiles) per 1,000 population.
