Test: The World Population- 2 - Question 1

What do we discuss about population distribution and density?

Detailed Solution for Test: The World Population- 2 - Question 1

Population Distribution and Density

  • Shapes: Population distribution refers to how people are spread out across a geographical area. The shape of the population distribution can vary, such as clustered, dispersed, or linear.

  • Designs: Population density is the number of people living in a specific area. It is often represented as the number of individuals per unit of land area. Different designs of population density can indicate urban, suburban, or rural areas.

  • Lines: Population distribution can be represented by lines on a map to show areas of high and low population density. These lines can help identify patterns of population distribution across a region.

  • Patterns: Patterns in population distribution and density can reveal trends such as urbanization, migration, and economic development. Understanding these patterns can help policymakers make informed decisions about resource allocation and infrastructure development.

Test: The World Population- 2 - Question 4

What percentage of the world's population is in the world’s ten most populous countries?

Detailed Solution for Test: The World Population- 2 - Question 4

Calculation:

  • First, we need to find the total population of the world.

  • According to the United Nations, the current world population is approximately 7.8 billion.

  • Next, we need to find the total population of the top ten most populous countries in the world.

  • The top ten most populous countries are China, India, United States, Indonesia, Pakistan, Brazil, Nigeria, Bangladesh, Russia, and Mexico.

  • The total population of these countries is approximately 5.7 billion.

  • Now, we can calculate the percentage of the world's population in the top ten most populous countries.

  • To do this, we divide the total population of the top ten countries by the total world population and multiply by 100.

  • (5.7 billion / 7.8 billion) * 100 ≈ 73.08%


Answer:

  • The percentage of the world's population in the world’s ten most populous countries is approximately 73.08%.

  • Therefore, option A (60%) is not the correct answer.

By understanding the nature of extreme climates like very hot or cold deserts, it becomes clear why they are considered uncomfortable for most individuals. The lack of resources, extreme temperatures, and challenging conditions make these environments difficult to thrive in.
Test: The World Population- 2 - Question 8

Who offers incentives to people to live in sparsely populated areas or move away from overcrowded places?

Detailed Solution for Test: The World Population- 2 - Question 8
Why Governments Offer Incentives to People

  • Population Distribution: Governments offer incentives to address population distribution issues. Sparsely populated areas may struggle with infrastructure development and economic growth, while overcrowded places face challenges like housing shortages and overburdened public services.

  • Economic Development: By incentivizing people to move to less populated areas, governments can stimulate economic development in those regions. This can create new job opportunities, attract investments, and boost local businesses.

  • Resource Utilization: Incentivizing people to live in sparsely populated areas can help better utilize natural resources, prevent environmental degradation, and reduce strain on infrastructure in overcrowded places.

  • Social Welfare: Governments may offer incentives to improve the quality of life for residents. By encouraging people to move away from overcrowded areas, they can reduce congestion, improve access to services, and enhance overall well-being.


Types of Incentives Offered by Governments

  • Tax Breaks: Governments may provide tax incentives, such as reduced income taxes or property tax discounts, to encourage people to move to sparsely populated areas.

  • Subsidies: Subsidies for housing, transportation, or utilities can make living in less populated areas more affordable and attractive to individuals and families.

  • Job Opportunities: Governments may create employment programs or offer incentives to companies to set up operations in sparsely populated regions, providing job opportunities for those who relocate.

  • Infrastructure Development: Investing in infrastructure projects, such as building roads, schools, healthcare facilities, and recreational amenities, can make living in sparsely populated areas more appealing.


By offering these incentives, governments aim to achieve a more balanced population distribution, promote sustainable development, and improve the overall well-being of their citizens.

Test: The World Population- 2 - Question 11

How many sets of factors influence migration?

Detailed Solution for Test: The World Population- 2 - Question 11
Factors influencing migration:

  • Push factors: These are the factors that compel individuals to leave their current location and migrate to a new one. Some common push factors include political instability, economic hardship, lack of job opportunities, natural disasters, and conflict.

  • Pull factors: These are the factors that attract individuals to a new location and encourage migration. Pull factors can include better job opportunities, higher wages, political stability, improved living conditions, and access to education and healthcare.


Additional factors influencing migration:

  • Social factors: Social networks and connections can play a significant role in influencing migration patterns. Individuals may choose to migrate to be closer to family members or friends, or they may be influenced by the experiences of others who have successfully migrated.

  • Cultural factors: Cultural differences between countries can also impact migration decisions. Individuals may be drawn to a new location because of its cultural attractions, language, traditions, or religious practices.
