Census Tracts and Addresses

[StephenGrassia3]

I have a dataset of patient addresses. I want to combine the address with cesus tracts. how would I go about inputing how may addresses are in each census tract so I can symoblize that amount and not show the exact location of the patients?

Hi Stephen,

If you have ArcGIS Pro you can use the Summarize Within tool.  If you are using ArcGIS Desktop, you can accomplish this using the Spatial Join tool.  Before running the tool, create a new field in the patient address feature class called something like "COUNT".  Calculate the value of this to 1 for each row.  When executing the Spatial Join you can specify a merge rule to SUM.  Here is a very old help document that shows this:

It worked. Thank you so much
