Population geography also studies human-environment interactions, including problems from those relationships, such as overpopulation, pollution, and others. [ 3 ] A few types of maps that show the spatial layout of population are choropleth , isoline , and dot maps.

Population dynamics overlap with another active area of research in mathematical biology: mathematical epidemiology, the study of infectious disease affecting populations. Various models of viral spread have been proposed and analysed, and provide important results that may be applied to health policy decisions.
In ecology, a population is a group of organisms of the same species which inhabit the same geographical area and are capable of interbreeding. [2] [3] The area of a sexual population is the area where interbreeding is possible between any opposite-sex pair within the area and more probable than cross-breeding with individuals from other areas.
