The rate at which a particular population is growing each year. It is calculated relative to a base population size and reflects the net impact of births, deaths, and migration. The growth rate in the United States was approximately 0.6% per year in 2002.
Average annual compound rate of change from 1990 to 1998. For example: Rate = 100*[((P98 / P90)^(1/8.25))-1].
The increase in a country's population during a certain period- usually one year- expressed as a percentage of the population when the period began. The population growth rate is the sum of the difference between the birth rate and the death rate- the natural population increase- and the difference between the population entering and leaving the country- the net migration rate.
A measure of how quickly the number of people in an area increases.
indicates how fast a population increases or decreases as a result of the interplay of births, deaths, and migration during a given period of time. Where the population is closed, meaning no migration, the population growth rate is the same as the rate of natural increase, i.e., the difference between the number of births and the number of deaths during a specified period of time. The three methods for computing the rate of growth based on the assumption with respect to the change are: arithmetic change, geometric change and exponential change.
The average annual percent change in the population resulting from a surplus (or deficit) of births over deaths and the balance of migrants entering and leaving a country. The rate may be positive or negative.
The annual percentage increase in the size of the population.
This refers to the increase in a country's population during one year, divided by the population at the start of that year. It reflects the number of births and deaths during the period and the number of people moving to and from a country. Source: World Bank
