I have a problem with the function buffers in QGIS. I prepared a layer with bus stops and buffers for them (500 m). Then I joined layer with buffers and layer with density of population. I want to know the number of inhabitants living within 500 m from the bus stop. That's why I use join attributes by location. Everything came out well, but the problem is the overlapping buffers. "Connected people" are in two or three buffers at once. And I need to know the number of inhabitants outside of these buffers. Is there any possibility of division between buffers or converted, so as not counted them a few at a time?
Orange and brown spots are inhabitants.
