The definition is: "The rate of increased size per unit time".
math
In geometric growth the ratios of successive terms is the same whereas in arithmetic growth the differences are the same.
the birth rate is the rate of birth in a population, the death rate is the number of deaths in a population and the growth rate is the growing numbers of the population.
Is continually increasing
The Variable Rate is the rate at which a number changes
math
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 definition is when individuals in a reproduce at a constant rate
Generally it would be the change in the variable in question divided by the change in time over which it took place.
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).
The definition of growth yield is the rate at which the size per unit time increases. This is very useful for farmers as it helps them decide which crops to grow.
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.
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).
