What structure of dispersion describes high densities of individuals in certain resource-rich areas and low densities elsewhere?

It is the Clumped distribution. People of a populace can be divided in various ways, called scattering designs. In uniform scattering, people are equally separated. In irregular scattering, people are haphazardly orchestrated. The most widely recognized spatial course of action is amassed scattering, in which people are grouped together.
