Growth rate is the percentage increase in a specific variable over a period of time, commonly used to measure the expansion of an economy, population, investment, or any other quantifiable factor. It is calculated by taking the difference between the final and initial values, dividing by the initial value, and then multiplying by 100 to express it as a percentage.
The definition is: "The rate of increased size per unit time".
math
the definition is when individuals in a reproduce at a constant rate
Population growth rate is the rate at which populations change in size over time as a fraction of the initial population. The formula used to measure growth rate is (birth rate + immigration) - (death rate + emigration).
Growth whose rate becomes even more rapid in proportion to the growing total number or size.
This is the definition of cancer. It will produce a large growth with uncontrolled activity.
How much a population increases per unit time. The growth rate can also be expressed as growth per unit time divided by the population - for example, so-and-so much increase per year.
The dependency rate is a demographic indicator that measures the ratio of dependent individuals (such as children and the elderly) to the working-age population within a given society. It helps to illustrate the level of support that the working population must provide for dependents.
Urban growth is the rate of growth of an urban population. It is different to urbanization which is the process by which there is an increase in proportion of a population living in places classified as urban: the movement from a rural to urban area.
A high growth venture is one that achieves more than 50% growth rate annually. A middle growth enterprise is one that achieves more than 20% but less than 50% growth rate annually. A lifestyle enterprise is one that achieves less than 20% annual growth. (Source: 1000ventures.com)
Growth whose rate becomes ever more rapid in proportion to the growing total number or sizeExponential growth occurs when the growth rate of the value of a mathematical function is proportional to the function's current value. Exponential decay occurs in the same way when the growth rate is negative. In the case of a discrete domain of definition with equal intervals it is also called geometric growth or geometric decay (the function values form a geometric progression).
Generally it would be the change in the variable in question divided by the change in time over which it took place.
