I have two tables. One for school districts, one for schools with the total number of each student in the school.
I created a float field in the districts table for student population. I want to populate this field with the sum of students in each school within each district.
Essentially, I need to select by location the schools in each district and assign the summary of their student population to the district student population field.
I feel like this is a simple task with ArcMap, but I can't afford their license.
