The main way individuals are added to the population (with animals) is the birth of new offspring.
New individuals are mainly added to a population through reproduction, either sexually or asexually. This process involves the combination of genetic material from two parents to produce offspring with a unique genetic makeup.

by being birthed or moving into the population.
The net recruitment rate (NRR) formula is calculated as the number of new individuals added to a population through recruitment, minus the number of individuals lost due to mortality or emigration, divided by the total population size. Mathematically, it can be expressed as: [ \text{NRR} = \frac{(N_{\text{new}} - N_{\text{lost}})}{N_{\text{total}}} ] where (N_{\text{new}}) is the number of new recruits, (N_{\text{lost}}) is the number of losses, and (N_{\text{total}}) is the total population size. This rate helps assess population stability and growth.
Migration of individuals into or out of a population provides a source of genetic variation. This movement introduces new genes into the gene pool, increasing diversity within the population.
Australia has a population of 23.2 million people and New Zealand has a population of 4.51 million. The two populations, when added together, equal 27,710,000.
