Question

what is the difference between over population and under population?

Answer 1

The term ‘overpopulation’ means too great a population for a given region to support. There may be two causes: (i) population growth exceeds the existing resource base; (ii) existing resources have been depleted.

Some authors distinguish absolute overpopulation (where the absolute limit of production has been attained but standards of living remain low) from relative overpopulation (where present production does not support the population but the production can be augmented).

The situation of overpopulation displays the following socio-economic characteristics: high unemployment, low incomes, low standards of living, high population density, malnutrition and famine.

Answer 2

1)Overpopulation: This is an area that has too many people and not enough resources to maintain a reasonable standard of living in that area. Resources may include food, jobs, technology, services, energy. Overpopulated areas often on verge of famine and have high emigration. Examples of overpopulation are in Bangladesh where pop. Density was 282 per km2 in 1850 but rose to 1127 per km2 by 2010. It has a population of approx 162 million 
                                                                                             2)Underpopulation: This is when there are not enough people to make full use of the resources and technology of the place they live in. Canada is said to be underpopulated because it could increase its population but still have a high standard of living. Canada exports food and has many mineral resources. Population density in Canada is 3.4 per km2. It has a population of approx 33.7 million
