San Bernardino County has variable CES 4.0 Scores depending on geographic location. As CES 4.0 Scores take into account both Pollution Burden scores and Population Characteristics, this dashboard aims to explore the areas with both the lowest and highest mean numbers of Asthma-related Emergency Department visits (per 10,000) and their percent of Poverty and Pollution Burden Score from 2015 to 2017 to visualize if differences in Poverty and Pollution Burden lead to differences in numbers of Asthma-related Emergency Department visits in San Bernardino County. This dashboard can guide public health response in San Bernardino County in targeting resources and environmental policy change within areas and populations with the most vulnerability to respiratory illness.
