I have dabbled with ArcGIS and QGIS a bit, and I consider myself a self-taught beginner with a whole lot to learn.
So, I have two layers: 1) census blocks, and 2) point data.
My goal is to calculate the sum of the point data within the census blocks to eventually create a choropleth map and to run regression models with the sums of the points as a dependent variable; however, some of the points are directly between blocks and are not truly within them, so the points in polygons tool seems to miss a lot of points.
Because I am interested in the effect of these points on the proximal blocks, I had the idea of creating a 15m buffer around the points, and summing up the number of buffers that each census block intersected, but I am at a loss for how to do this in QGIS. So far, I have tried to join attributes by location, intersections, unions, and they all don't seem to get me where I need to be.
If anyone has an idea how to do this, I would greatly appreciate.
I attached a sample picture of my layout with the intersecting census blocks selected. Please excuse my labeling.
