Population Studies

Malthus predictions did not come to pass mainly because

• • food supply and population grew at the same rate.

• • the use of machines in agriculture was discouraged.

• • a lot of people died during epidemics

• • many people emigrated to the new lands

In determining the growth of a country's population, infant mortality is a component of

• • immigration rate.

• • fertility rate.

• • net migration.

• • death rate.

The dependency ratio of a country is the

• • the children and aged who rely on the active population for support

• • people who are cared for by their extended families

• • total active population who depends on government for survival

• • number of children who depend on their parents for survival

The Malthusian theory of population is best illustrated when

• • the size of the population and available resources are equal

• • both population and food supply increase at the same rate

• • food supply increases much faster than population growth

• • population increases much faster than food supply

The rate of growth of population is

• • initial population plus number of births and net migration

• • birth rate less death rate plus net migration

• • the difference between birth rate and death rate

• • the number of immigrants plus number of births

A positive effect of a rapid population increase is

• • an excessive budget deficit

• • a reduction in standard of living

• • a wider market for goods and services

• • a higher dependency ratio

What is the percentage of the working population?

 

• • 75%

• • 60%

• • 45%

• • 15%

What is the dependency ratio?

• • 2:3

• • 3:2

• • 1:2

• • 6:1

Malthus' major contention is that

• • population increase in arithmetic progression while food production increased in geometric progression

• • population increased in geometric progression while food production increased in arithmetic progression

• • population and food growth rate will, in future, be at par

• • nations have to get enough manpower to cultivate available land for food

positive checks as envisaged by Thamos Malthus can be prevented if

• • date rate is reduced

• • marriage is abolished

• • more hospitals are built

• • moral restraint is adopted
