Nice exercise, Hans, thank you. I think I'll try it on residential properties across 140 estates in Milton Keynes. I'm in the GIS Team at the city council.

You need a polygon layer for which you want to calculate the densities. These can be for example administrative boundaries. Buildings come from OpenStreetMap and the data are available world wide.
