2. A population is all the organisms that both belong to the
same group or species and live in the same geographical
area. In ecology the population of a certain species in a
certain area is estimated using the Lincoln index. The area
that is used to define a sexual population is such that
inter-breeding is possible between any pair within the
area and more probable than cross-breeding with
individuals from other areas. Normally breeding is
substantially more common within the area than across
the border.
In sociology, population refers to a collection of human
beings. Demography is a social science which entails the
statistical study of human population. This article refers
