Demographers figure out population growth by comparing birth rates and death rates.
Birth rates and death rates
Demographers study human population size, density and distribution, movemenet, and its birth and death rates
because birth rates and death rates relate to population. the birth rate shows how much a population is increasing, and death rates show how much a population is decreasing. when you average the two out, it will give you the population(:
For the very simple reason that birth rates influence the rate at which the population grows whereas the death rate determines the rate at which it decreases. Net migration is another factor that needs to be taken into account.
the answer is by comparing birthrates and death rates
If birth rates exceed death rates, the population increases proportionally. If death rates exceed birth rates, the population decreases.
Birth rates rise as death rates fall?
The top rates for CD's across the country and worldwide are 1.5 and 1.75 percent. These rates for certificate of deposits have higher daily compounds.
The tendency of a population to shift from high birth and death rates is called a demographic transition.
Canada's birth/death rates per 1000 are: birth: 10.12 death: 10.8
