Question

4. 'The fertility increases the population whereas mortality decreases the
population. Describe the statement with examples.​

Answer 1

Hey mate! I've taken some notes down that may or may not help ya.

Here:

"Human females are most fertile between teen years and mid-forties.

Human males are usually fertile throughout adulthood, but sperm starts to diminish during middle-age.

The effect of mortality on population structures is to reduce the component of the population in which the mortality occurs. The effect of this is to raise the population in the upper age groups substantially. Women have higher life expectancy than men wherever they live.

The major factors affecting the population are birth, death, and migration. Birth increases the population while death decreases the population. Migration also causes population change. Internal migration does not make any changes but international migration makes the differences in the size of the population.

The rate of natural increase of a population depends on birth and death rates, which are strongly influenced by the population age structure."

Answer 2

The factors that affect the demographic divide are called as popualtion domains that is mortality, fertility and migration. The fertility rate is the rate that states the number of live children ever born to a woman and is proportional to the average annual popualtion.

• As the fertility rate increase so does the population and mortality decreases due to the improvement in medical technology and facilities.

• As the rise of innovation and technology lead to baby boom all around the world after 1800.
