I'm using QGIS and trying to solve the following problem.
I want to show the area where such number of people (that could be hosted/served) lives around this points (for instance, using circle diagrams).
I thought about creating multibuffer, then counting the number of people living
in each of them and manually trying to find the most appropriate size of it.
However, I believe there is more rational option.
Could you please propose any solutions?
