Hello! I’m working on a project to calculate the number of housing units per acre within a specified area. I’ve managed to summarize my housing data, which includes unit numbers and acres, within individual city block polygons. However, I’d like to select a group of city blocks via a widget in a web app and display the units per acre of the total area of the blocks selected. Is there a way to do this without summarize within or creating a new layer every time I select new blocks?
