Thus, if the growth remained constant, country’s population would double from the 2006 figure from 33 million to 66 million by 2084. The doubling time is the characteristic unit (natural unit of scale) for the exponential growth equation, and its inverse for exponential decay is half-life.įor example, let’s take some arbitrary net population growth of 0.9% in 2006, dividing 70 by 0.9 equals an approximate doubling time of 78 years. This time is calculated by dividing the natural logarithm of 2 by the growth exponent or by dividing approximately 70 by the percentage growth rate (or, more precisely, by the number 72, which we will talk about later). It has a continuous-time or period of doubling, which we get directly from the growth rate. When the relative growth rate is constant, the quantity is subject to exponential growth. It applies to population growth, inflation, resource extraction, consumption of goods, compound interest, and many other things that grow over time. The Doubling time defines the time it takes for the population to double in size/value. See also other calculators related to finances, or math.
