I am trying to perform a density analysis of a point shapefile on ArcMap. I am unsure of what to insert for population field. I've tried the actual number of people in the census tract where my point is and also tried adding a column to insert count (of points), so that each point has a count of 1. I have also left it as None. Neither works.
I get 2 types of errors:
- all input points are identical
- errors in executing grid expression
