Population
From The Art and Popular Culture Encyclopedia

"In the days before Pasteur man's population was maintained approximately constant from generation to generation by a cybernetic system in which the principal feedback element at the upper limit was disease. The crowd-diseases — smallpox, cholera, typhoid, plague, etc. — are, by the ecologist, labeled "density-dependent factors," whose effectiveness in reducing population is a power function of the density of the population. No growth of population could get out of hand as long as the crowd-diseases were unconquered, which means that man did not have to sit in judgment on man, to decide who should have a cover at Nature’s feast and who should not." --Nature and Man's Fate (1965) by Garrett Hardin |

A population is the number of all the organisms of the same group or species, which live in a particular geographical area, and have the capability of interbreeding.
The area that is used to define a sexual population is defined as the area where inter-breeding is potentially possible between any pair within the area, and where the probability of interbreeding is greater than the probability of cross-breeding with individuals from other areas.
In sociology, population refers to a collection of humans. Demography is a social science which entails the statistical study of human populations. This article refers mainly to the human population.
