Population size - In population genetics and population ecology, population size (usually denoted N) is the number of individual organisms in a population.

Effective population size - In population genetics, the concept of effective population size Ne was introduced by the American geneticist Sewall Wright, who wrote two landmark papers on it (Wright 1931, 1938). He defined it as "the number of breeding individuals in an idealized population that would show the same amount of dispersion of allele frequencies under random genetic drift or the same amount of inbreeding as the population under consideration".

Population viability analysis - Population viability analysis(PVA) is a branch of conservation biology dealing with techniques (usually simulation modelling) for determining the genetic diversity, spatial and temporal features of a population so as to evaluate the risk of extinction for that population. Some of the aims of PVA are to identify minimum viable population size for a species and set recovery targets for conservation managers.

Population momentum - Population momentum is an effect which causes population growth. This phenomenon refers to the percentage of the population that are in their child bearing years who have not yet had children, and thus are scheduled to eventually have children which add to the population through reproduction.
