I have spatially joined a polygon file with census tracts of areas in Houston with a theft occurrence point shapefile. The attribute table contains a field that represents different classes of theft (ie. Class A: 0−1000, Class B: 1001−2000 etc). I want to calculate the frequency of classes in each of my census tracts. So in essence how many different theft classes occur in each of the census tracts. I have figured out how to get the count, but this is not what I want. How would I go about obtaining and representing the frequency?
