ANSWER :-
What we might talk about as population size is actually population density, the number of individuals per unit area (or unit volume).
Population growth is based on four fundamental factors: birth rate, death rate, immigration, and emigration.
Population growth rate = (birth rate + immigration) - (death rate + emigration).
"Per capita rates" are calculated as the number of events (births, deaths, or growth) divided by the number of individuals in the population over a specific time period.
