Formula of population growth
The "population growth rate" is the rate at which the number of individuals in a population increases in a given time period, expressed as a fraction of the initial population. Specifically, population growth rate refers to the change in population over a unit time period, often expressed as a percentage of the number of individuals in the population at the beginning of that period.

WebSep 23, 2024 · Population growth = r N [ K − N K] Notice that when N is almost zero the quantity in brackets is almost equal to 1 (or K / K) and growth is close to exponential. When the population size is equal to the carrying capacity, or N = K, the quantity in brackets is equal to zero and growth is equal to zero. WebSep 5, 2024 · The Population Growth Rate ( r ) The population growth rate (sometimes called the rate of increase or per capita growth rate, r) equals the birth rate ( b) minus the death rate ( d) divided by the initial population size (N 0 ).
