Title
Environmental Health Hazard Index [United States]
Description
ENVIRONMENTAL HEALTH HAZARD INDEX Summary The environmental health hazard exposure index summarizes potential exposure to harmful toxins at a neighborhood level. Potential health hazards exposure is a linear combination of standardized EPA estimates of air quality carcinogenic (c), respiratory (r) and neurological (n) hazards with i indexing census tracts. Where means and standard errors are estimated over the national distribution. Interpretation Values are inverted and then percentile ranked nationally. Values range from 0 to 100. The higher the index value, the less exposure to toxins harmful to human health. Therefore, the higher the value, the better the environmental quality of a neighborhood, where a neighborhood is a census block-group. Data Source: National Air Toxics Assessment (NATA) data, 2014.
