  2. Mortality Rate

  3. Immigration

  4. Economic Development
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

While economic development can influence population growth indirectly through factors like improved healthcare and education, it is not a direct driver of population growth like fertility rate, mortality rate, or immigration.

Multiple choice

What is the primary focus of Economic Demography?

  1. The impact of population growth on economic development

  2. The role of economic factors in shaping population trends

  3. The relationship between population size and resource allocation

  4. The influence of cultural norms on economic behavior
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Multiple choice

Which theory suggests that population growth is driven by economic opportunities?

  1. The Demographic Transition Theory

  2. The Malthusian Theory of Population

  3. The Economic Opportunity Theory

  4. The Social Exchange Theory
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The Economic Opportunity Theory posits that population growth is influenced by economic factors such as job availability, income potential, and access to resources, which can encourage migration and higher fertility rates.

Multiple choice

What is the term used to describe the aging of a population?

  2. Population Stagnation

  3. Population Inversion

  4. Population Aging
Reveal answer Fill a bubble to check yourself
D Correct answer

Multiple choice

What is the term used to describe the relationship between population growth and economic growth?

  1. The Demographic Dividend

  2. The Demographic Trap

  3. The Demographic Transition

  4. The Demographic Momentum
Reveal answer Fill a bubble to check yourself
A Correct answer
