The rate at which a population increases in size if there are no density-dependent forces regulating the population is known as the intrinsic rate of increase.
Where (dN/dt) is the rate of increase of the population and N is the population size, r is the intrinsic rate of increase. This is therefore the theoretical maximum rate of increase of a population per individual . The concept is commonly used in insect population biology to determine how environmental factors affect the rate at which pest populations increase. See also exponential population growth and logistic population growth.

Famous quotes containing the words intrinsic, rate and/or increase:
“The truth is that literature, particularly fiction, is not the pure medium we sometimes assume it to be. Response to it is affected by things other than its own intrinsic quality; by a curiosity or lack of it about the people it deals with, their outlook, their way of life.”
—Vance Palmer (1885–1959)
“I don’t know but a book in a man’s brain is better off than a book bound in calf—at any rate it is safer from criticism. And taking a book off the brain, is akin to the ticklish & dangerous business of taking an old painting off a panel—you have to scrape off the whole brain in order to get at it with due safety—& even then, the painting may not be worth the trouble.”
—Herman Melville (1819–1891)
“The increase in wisdom can be measured precisely by the decrease in bile.”
—Friedrich Nietzsche (1844–1900)
