Dissimilarity Index for Neighborhood Level Data

[Melissa Sherry]

Hello,

I need to calculate a racial dissimilarity index score for each of 52 neighborhoods in my study. For each neighborhood, I have the proportion of individuals who are black and the proportion white (scale of 0-1). I have tried using "seg" to calculate a dissimilarity index score for each neighborhood, but I only get a dissimilarity index score for the whole of my data, not one value for each neighborhood. The code I used was:

seg paa15 pwhite15, d by(neighborhood) generate (d dissimindex)

Can anyone help me figure out what I am doing wrong, and how to get the index score separately for each of my neighborhoods?

Thank you!

? abs(pblack - pwhite)/2
