1. Population size- This describes the total population in the area. It helps to ascertain if there is any need for population protection or any need for breeding.
2. Population density- It determines that large organisms live in less populated density places whereas it is easy to find groups and mates in a high populated places.
3. Population distribution- A population may have a uniform, random, or clumped distribution pattern
