I'm new to QGIS, always used ArcMap, and I'm struggling to find out how to best display population density at the block group level for a county (the most granular level of detail for census geography). I have the shapefile for the block groups, and I've joinedthe csv containing my population data per block group to the shapefile, but now I'm at a loss on:
1) how to best display the population density
2) the method for executing the task in QGIS.
Most of the block groups have populations ranging from 25-100 people. Would it be best to have 1 dot equal 25 people per census block? How do I create this type of map in QGIS?
