Hello: I am looking for a tool that calculates population centroids per TAZ (traffic area zone). These are zones similar in size to school districts. This would seem like such a common need, that I'm surprised not to find a simple tool to do it. Bill Hubler has given advice in past forums on this. I understand his advice but I don't know how to make grids of x, and grids of y coordinates.
The centroid formula is the same as for any weighted average. The problem I have is, again, attributing my population data with its coordinates such that the centroid formula can be applied.
