Methods:
This analysis answered the question: "Is the black population
percentage within a 2-mile radius around hazardous waste
facilities in Orange County, Florida significantly different than
within the rest of the community?" TRI facilities were used as
the hazardous waste facilities. The Orange County boundary
was used to Clip the TRI sites and census data. A 2-mile buffer
was then placed around each facility. The overlapping
boundaries were removed using the Dissolve tool. The resulting
polygon represented the potentially hazardous areas in Orange
County due to TRI proximity. A Summary analysis was used on
the census data to find the overall percentage of black residents
in Orange County and the percentage of black residents within
two miles of a TRI facility. The potentially hazardous areas and
their black population densities are expressed on the map.
