Hello all. I am a new ArcGIS user, and am currently in an "Intro to GIS" class at school. We had an assignment mapping demographics for our state and Covid information along with drive time to hospitals. The last part of the assignment we are to create an analysis question. Mine is "where are the 85+ population within those drive times. I have been working on this for about 16 hours and none of my analysis procedures have worked. I am wondering if i have redundant layers, or layers that were already analyzed wrong, etc? Any help would be appreciated. the link is https://arcg.is/1DruXz0
