Who said that Asia has many places where people are few and few place where people are very many?
  • a)
    George B. Cressey
  • b)
    Frank G. Cressey
  • c)
    Aristotle
  • d)
    Frances Babcock
Correct answer is option 'A'. Can you explain this answer?

George B. Cressey, an American geographer, said that Asia has many places where people are few and few places where people are very many.

Reasoning:
Asia is the largest and the most populous continent in the world, with a wide range of geographic features and climatic conditions. Cressey's statement is based on his observation of the distribution of population in Asia. He noted that there are some regions in Asia where the population density is very high, while in other parts of Asia, the population density is very low.

Places where people are few:
1. Siberia: It is a vast region in the northern part of Asia, covering almost 77% of Russia's territory. Siberia is known for its harsh climate, with long, cold winters and short, cool summers. Due to its extreme climate and remote location, the population density in Siberia is very low.

2. Gobi Desert: It is a large desert region in Asia, covering parts of northern and northwestern China and southern Mongolia. The Gobi Desert is one of the most inhospitable places on Earth, with very little rainfall and extreme temperature variations. As a result, the population density in the Gobi Desert is very low.

Places where people are very many:
1. South Asia: It includes countries like India, Pakistan, Bangladesh, and Sri Lanka, which have a high population density due to their large population and small land area.

2. East Asia: It includes countries like China, Japan, and Korea, which are densely populated due to their large population and limited arable land.

Conclusion:
Cressey's statement highlights the diverse population distribution in Asia, with some regions having a high population density, while others have a low population density. This variation is due to factors such as climate, topography, and economic development.

    Negative
  • b)
    Positive
  • c)
    Neutral
  • d)
    Not defined
Correct answer is option 'A'. Can you explain this answer?

Deepika Reddy answered
Negative correlation between economic development and population growth

Economic development and population growth have a complex relationship, which has been studied by economists and social scientists over the years. The correlation between these two factors can be positive, negative, or neutral depending on the context.

However, in most cases, the correlation between economic development and population growth is negative. This means that as economic development increases, population growth decreases. This may seem counterintuitive, but there are several reasons why this correlation exists.

Factors contributing to negative correlation

1. Urbanization: As countries develop economically, people tend to move from rural to urban areas. This leads to a decrease in the birth rate and an increase in the cost of living, which makes it less affordable for families to have more children.

2. Education: With economic development comes an increase in education levels. People who are better educated tend to have fewer children as they focus on their careers and personal goals.

3. Healthcare: Economic development leads to an increase in healthcare facilities and services. This leads to a decrease in infant mortality rates and an increase in life expectancy, which reduces the need for families to have more children.

4. Family planning: With increased economic development comes an increase in access to family planning services. This allows families to plan their pregnancies and have fewer children.

Conclusion

In conclusion, the correlation between economic development and population growth is negative. As countries become more developed, people tend to have fewer children due to factors such as urbanization, education, healthcare, and family planning. This negative correlation is beneficial for the economy as it leads to a decrease in the dependency ratio and an increase in the working-age population, which can drive economic growth.

What is the total world population according to 2021?
  • a)
    5.9 billion
  • b)
    6.9 billion
  • c)
    7.9 billion
  • d)
    None
Correct answer is option 'C'. Can you explain this answer?

The total world population according to 2021 is 7.9 billion.

Factors contributing to the world population growth:

1. Advancements in medicine and healthcare: With the discovery of vaccines and advancements in medical treatments, the number of deaths due to illnesses and disease has decreased, leading to an increase in the world population.

2. Increase in life expectancy: People are living longer than ever before due to better healthcare and medical treatments, which has led to an increase in the world population.

3. Fertility rates: Fertility rates have been high in many parts of the world, leading to an increase in the number of births and subsequently the world population.

4. Immigration: People moving from one country to another has also contributed to the world population growth.

Effects of the world population growth:

1. Strain on resources: As the population grows, there is an increased demand for resources such as food, water, and energy, which can lead to shortages and price increases.

2. Environmental impact: With more people on the planet, there is an increase in pollution, deforestation, and other environmental issues.

3. Urbanization: As people move to cities, there can be overcrowding and strain on infrastructure.

4. Globalization: The growth in population has contributed to the globalization of the economy, culture, and politics.

Conclusion:

The world population is constantly growing, and it is important to consider the effects of this growth on the planet and its resources. Sustainable development and responsible resource management are important to ensure a better future for all.

Who offers incentives to people to live in sparsely populated areas or move away from overcrowded places?
  • a)
    Citizens
  • b)
    Nations
  • c)
    Governments
  • d)
    None
Correct answer is option 'C'. Can you explain this answer?

Anuj Patel answered
Governments offer incentives to people to live in sparsely populated areas or move away from overcrowded places.

Reasons for offering incentives:
- To distribute population evenly across a country
- To reduce pressure on resources and infrastructure in overcrowded areas
- To promote development in underdeveloped areas

Examples of incentives:
- Tax breaks or subsidies for businesses that relocate to sparsely populated areas
- Housing incentives such as low-interest loans or grants for those who move to underdeveloped areas
- Education and healthcare subsidies to attract professionals to underdeveloped areas
- Job opportunities and training programs in underdeveloped areas
- Infrastructure development in sparsely populated areas to make them more attractive for settlement

Overall, the aim of offering incentives is to create a more balanced and sustainable distribution of population and resources across a country.

Anand Das answered
**Population Growth in Developed Countries Compared to Developing Countries**

**Introduction**
Population growth refers to the increase in the number of individuals in a particular population over a specific period of time. It is an important indicator of a country's social and economic development. The growth rates of populations in developed and developing countries differ significantly due to various factors.

**Definition of Developed and Developing Countries**
Before delving into the differences in population growth between developed and developing countries, it is important to understand the definitions of these terms:

1. Developed Countries: These countries have a high level of economic development and are characterized by advanced industries, high living standards, and well-established infrastructure. Examples of developed countries include the United States, Canada, Germany, and Japan.

2. Developing Countries: These countries are characterized by a lower level of economic development, limited infrastructure, and lower living standards. They often have a higher proportion of people engaged in agricultural activities and may be experiencing rapid industrialization. Examples of developing countries include India, Brazil, Nigeria, and Bangladesh.

**Factors Influencing Population Growth**
The population growth rates in developed and developing countries are influenced by various factors, including:

1. Birth Rates: The number of births per 1,000 people in a given population. Developing countries tend to have higher birth rates than developed countries due to factors such as cultural norms, lack of access to contraceptives, and higher infant mortality rates.

2. Death Rates: The number of deaths per 1,000 people in a given population. Developed countries generally have lower death rates than developing countries due to advancements in healthcare, sanitation, and nutrition.

3. Migration: The movement of people from one region or country to another. Developed countries often experience significant immigration, which can contribute to population growth. In contrast, developing countries may have higher rates of emigration as people seek better economic opportunities elsewhere.

**Population Growth in Developed Countries**
In developed countries, population growth is generally low. There are several reasons for this:

1. Declining Birth Rates: Developed countries often have lower birth rates due to factors such as increased access to education and healthcare, urbanization, and changing societal norms.

2. Aging Population: Developed countries tend to have aging populations, with a larger proportion of older individuals compared to younger ones. This is mainly due to declining birth rates and increased life expectancy.

3. Family Planning: Developed countries often have well-established family planning programs and access to contraception, which allow individuals to make informed choices about family size.

**Population Growth in Developing Countries**
In contrast, developing countries generally experience higher population growth rates due to a combination of factors:

1. High Birth Rates: Developing countries often have higher birth rates due to factors such as cultural norms, limited access to education and healthcare, and high infant mortality rates. These factors can contribute to larger family sizes.

2. Limited Access to Contraception: Many developing countries face challenges in providing widespread access to contraception and family planning services, resulting in higher birth rates.

3. Lack of Economic Opportunities: Developing countries may have limited economic opportunities and high levels of poverty. In such circumstances, families may rely on having more children to contribute to household income or provide support in old age.

4. Improvements in Healthcare: While healthcare in developing countries has improved over time, it still lags behind that of developed countries. Higher mortality rates due to inadequate healthcare can contribute to larger population growth.

**Conclusion**
In summary, population growth rates differ significantly between developed and developing

In which year Thomas Malthus stated his theory?
  • a)
    1790
  • b)
    1792
  • c)
    1786
  • d)
    1798
Correct answer is option 'D'. Can you explain this answer?

Saumya Pillai answered
Thomas Malthus stated his theory in the year 1798.

Background Information:

Thomas Malthus was an English economist who lived from 1766 to 1834. He was concerned about the issue of overpopulation, and he believed that if the population continued to grow unchecked, it would eventually outstrip the resources available to support it.

Malthus's Theory:

Malthus's theory, which he first outlined in his 1798 book "An Essay on the Principle of Population," can be summarized as follows:

- Population growth is exponential, meaning that it increases at a geometric rate.
- Food production, however, is only able to increase arithmetically, meaning that it increases at a much slower rate than population growth.
- As a result, there will always be more people than there are resources to support them. This leads to competition for resources, which in turn leads to poverty, famine, and disease.
- Malthus believed that the only way to prevent this outcome was to limit population growth, either through moral restraint (abstaining from sex) or through other means such as war, disease, or natural disasters.

Impact of Malthus's Theory:

Malthus's theory was controversial at the time, and it continues to be debated today. Some critics argue that his predictions have not come true because technological advancements have allowed us to increase food production and improve living standards. Others, however, point to the ongoing problems of poverty, hunger, and environmental degradation as evidence that Malthus's concerns were justified. Regardless of one's views on the matter, Malthus's theory remains an important contribution to the study of population and its impact on society.

What percentage of the world population lives in about 10 percent of its land area?
  • a)
    94
  • b)
    90
  • c)
    92
  • d)
    88
Correct answer is option 'B'. Can you explain this answer?

Percentage of world population living in 10 percent of land area

In this question, we are asked about the percentage of the world population that lives in about 10 percent of its land area. The correct answer is option B, which is 90 percent. Let's break down why this is the case.

Explanation:

- Distribution of Population: The world's population is not evenly distributed across its land area. Some regions are more densely populated than others. For example, the population density in urban areas tends to be higher than in rural areas.
- Population Density: The population density is the number of people per unit of area. When we look at the population density of different regions of the world, we see that some areas have much higher population densities than others.
- High Population Density Areas: The areas with the highest population densities tend to be urban areas, particularly in developing countries. These areas are often characterized by high-rise buildings, crowded streets, and a lack of open space.
- Percentage of World Population: When we look at the percentage of the world population that lives in these high population density areas, we find that it is around 90 percent. This means that the vast majority of the world's population lives in just 10 percent of its land area.
- Implications: This concentration of the world's population in just a few areas has significant implications for issues like resource allocation, urban planning, and environmental sustainability.

Conclusion:

In summary, the correct answer to this question is that about 90 percent of the world population lives in about 10 percent of its land area. This is due to the uneven distribution of population density across different regions of the world.

Why is Japan’s population decreasing?
  • a)
    No pull factors
  • b)
    Terrorism
  • c)
    Government policies
  • d)
    Low fertility rate
Correct answer is option 'D'. Can you explain this answer?

Naina Sharma answered
That gap between births and deaths has put Japan in a demographic squeeze. As the number of births goes down, there are fewer young people entering its work force. That means fewer people to replace retiring workers and support them as they age, a situation that poses a serious threat to Japan’s economic vitality and the security of its social safety net.

In which stage of Demographic Transition, population explosion took place:
  • a)
    Stage I
  • b)
    Stage II
  • c)
    Stage III
  • d)
    Post Stage III
Correct answer is option 'B'. Can you explain this answer?

Rajesh Gupta answered
A consequence of the decline in mortality in Stage Two is an increasingly rapid growth in population growth (a.k.a. "population explosion") as the gap between deaths and births grows wider and wider. Note that this growth is not due to an increase in fertility (or birth rates) but to a decline in deaths.

What is the one way by which the population size changes?
  • a)
    Determination
  • b)
    Competition
  • c)
    Migration
  • d)
    None
Correct answer is option 'C'. Can you explain this answer?

Population Size Changes


  • Migration: One way by which the population size changes is through migration. Migration refers to the movement of individuals from one location to another. This can be either immigration (moving into a population) or emigration (moving out of a population). When individuals migrate into a population, the population size increases. Conversely, when individuals migrate out of a population, the population size decreases.

It was another 123 years before it reached two billion in 1927, but it took only 33 years to reach three billion in 1960. Thereafter, the global population reached four billion in 1974, five billion in 1987, six billion in 1999 and, according to the United States Census Bureau, seven billion in March 2012.

What percentage of the world's population is in the world’s ten most populous countries?
  • a)
    60
  • b)
    58
  • c)
    62
  • d)
    64
Correct answer is option 'A'. Can you explain this answer?

The percentage of the world's population in the world’s ten most populous countries is 60%.

Explanation:

- According to the United Nations, the world's population in 2020 was approximately 7.8 billion people.
- The ten most populous countries in the world, in descending order, are China, India, United States, Indonesia, Pakistan, Brazil, Nigeria, Bangladesh, Russia, and Mexico.
- The combined population of these ten countries is approximately 5.8 billion people.
- To calculate the percentage of the world's population in these ten countries, we divide the population of the ten countries by the world's population and multiply by 100: (5.8 billion / 7.8 billion) x 100 = 74.4%
- Therefore, approximately 74.4% of the world's population lives in the ten most populous countries.
- However, the question asks for the percentage of the world's population in the top ten countries. Therefore, we need to subtract the population of the 10th country, Mexico, from the total population of the ten countries: (5.8 billion - 129.2 million) / 7.8 billion x 100 = 59.4%
- Rounded to the nearest whole number, the answer is 60%.

    Dictatorship
  • c)
    No emigration allowed
  • d)
    Rich in natural resources
Correct answer is option 'D'. Can you explain this answer?

Naina Sharma answered
Asia has historically had a higher population density. One of the biggest reasons is that rice provides so much more calories per acre than wheat and barley. Especially before the introduction of maize and potatoes during the Columbian exchange, this was a huge reason for the high population density.
