Describe the relationship between population density and population distribution

All the individuals of the same species living in a given geographical area is defined as population. The average number of individuals of a population living in a unit area is the population density of an organism. For example, if a population of 50 birds live in an area of 50 square meters, then a density of bird is 1 bird per square meter. Thus, population density is just the average number of individuals in a unit area. The individuals in a population is not uniformly distributed in a given area but they may be in small group or sparsely distributed. So, population distribution tells how the individuals are distributed in a given area.
