Moving out of a population is called emigration. (Moving into a population is called Immigration.)
Emigration.
Population Shift
called immigration, and it can increase genetic diversity within the population. Immigrants may bring new alleles or traits that can contribute to the overall fitness of the population. However, immigration can also introduce new diseases or disrupt existing social structures.
The number of individuals in the population is the population's size. If a population is small enough you will be able to determine the size by counting the individuals.

The movement of humans into a population is called migration.
The movement of people within a country is called internal migration. This refers to individuals relocating from one place to another within the same country.
An interacting group of individuals of the same species is called a population. Members of a population share a common gene pool and can potentially interbreed with one another. Populations play a crucial role in ecology and evolution.
The movement of genes into and out of a gene pool is called gene flow. Gene flow occurs when individuals migrate between populations and introduce new genetic variation or when individuals leave a population, reducing the amount of genetic diversity.

The group of individuals used to represent a population is called the sample. It should have the same statistics as the population, though be of a smaller size.
