The term described to use this number is called "population density".
The correct answer is population density.
The population density is the measurement of the population present in an unit area. In this case in a square kilometer, 200 deer are present; it is a representation of the population density of the deer in that particular region. In ecology the population density is used to keep a record of the density and distribution of species present in an area at a particular time.
