Is there a way to convert from polygon to points based on population of the polygon similar to dot density symbology

ChrisRichmond

I can display the number of patients by census tracts using dot density but I also want to display expected percent change in the future. I don't think I can do both of those with symbology, is there a way to convert from a polygon to points based on the number of patients by census tract so that I have a feature class that looks like a dot density?

You need to Use Create Random Points tool Create Random Points—Help | ArcGIS Desktop :

but before that , create short integer field and calculate the count of point (Value / the value per one point )

and use this field in Create Random Point tool as number_of_points_or_field

and don't forget to define your polygon feature class as constraining_feature_class

I'm glad for that.

Thank you, don't know why I didn't think of that but that worked perfectly for what I was needing. Thanks again Abdullah
