Inequity Identification Tool (IIT) Noise Cost by County

Metadata Updated: April 19, 2024

This file contains the US county estimates of the noise cost from roads within that county, population counts for different demographics, estimates of how much noise cost from roads each demographic is absorbing, and the noise-equity ratio for each demographic--the percent of noise cost borne divided by the percent of population within the county. The cost of noise pollution is estimated in a separate shapefile and the results are aggregated together through FHWA's Inequity Identification Tool (IIT).
