Answer #1

To calculate the variation in growth rates of the world population of a time period is

A positive growth rate indicates that the population is increasing, and negative indicates decreasing.

and growth rate is 0 indicates there is no change in population .

A growth rate must be zero when there are significant changes in the birth rates , death rates, immigration rate.

Another appropriate measure is net reproduction rate.

In the absence of migration , a net reproductive rate of more than 1 indicates that the population of female is increasing.

And less than 1 represent that the population of female is decreasing.

Epidemiologists are concerned with population growth as it relates to potential healthcare issues. Why do rates and measures of population change use the “total mid-year population” instead of the “end-of-year population?” What makes one measurement more effective than the other? Choose a real or a hypothetical example to explain how using the “end-of-year population” affects data collection and outcomes.

A class of models for population growth rates in marine fisheries assumes that the harvest from fishing is proportional to the population size. One such fishery uses the following quadratic model, expressed in function notation. G(n) = 0.5n - 0.2n2. Here G is the growth rate of the population (in millions of tons of fish per year), and n is the population size (in millions of tons of fish). Calculate G (1.64)
