Population growth is a change in population at any time and can be calculated as a change in the number of individuals in a population using "per unit time" for measurement.
Further Explanation
The term population growth refers to all species, but always refers to humans, and is often used informally as a demographic designation of the value of population increase, and is used to refer to world population growth. Population growth itself is influenced by factors of birth, death, and migration. In demographics, there is a term increase in a natural population and an increase in the total population. Where natural population growth is only influenced by births and deaths, while total population growth is affected by births, deaths, in-migration, and out-migration (emigration).
Back to the population growth rate. The rate of population growth each year in a certain period is called the population growth rate expressed in percentage units (%). This population growth rate also reflects the rate of population growth of an area every year. The higher population growth rate indicates a faster rate of population growth. Conversely, if a low population growth rate shows a slow population growth rate.
When population growth can exceed the loading capacity of an area or environment, the results end with overpopulation. Disruptions in human populations can cause problems such as pollution and traffic congestion, even though they can be covered by technological and economic changes. This region can be considered "underpopulated" if the population is not large enough to manage the economic system.
Growth value = (end population period - initial period population) / initial population period
Growth ratio = Growth value X 100%
