Percentage of county residents with completed COVID-19 vaccination by census tract of residence. Source: California Immunization Registry. Note: Number of people with completed vaccination is the number of county residents who either received a vaccine requiring a single dose or received the final dose of a vaccine requiring multiple doses. Percent of residents vaccinated and population age 5 years and older is based in part on estimates of the number of people residing in the census tract from a population-based survey sample, which is subject to error. As a result, percent vaccinated may be over- or under-estimated. For this reason, the displayed percent of residents vaccinated in a census tract is capped at 95%.
