What is the average population density of the world?
The average population density of the world is approximately 45 persons per square kilometer.
Detailed
To calculate the average population density of the world, we need to consider the total population and the total land area.
1. Total population: According to the United Nations, the estimated global population as of 2021 is around 7.9 billion people.
2. Total land area: The total land area of the world is approximately 148.94 million square kilometers.
3. Population density calculation: Divide the total population by the total land area to get the average population density.
Population density = Total population / Total land area
Population density = 7.9 billion / 148.94 million square kilometers
Population density ≈ 52.99 persons per square kilometer
4. Rounding off: Since the options provided are in whole numbers, we round the population density to the nearest whole number.
Rounded population density ≈ 53 persons per square kilometer
Therefore, the average population density of the world is approximately 53 persons per square kilometer.

Explanation:
To determine the lowest levels of literacy and development in a population, we need to look at the characteristics of a population pyramid. The population pyramid is a graphical representation of the age and sex distribution of a population. The different characteristics indicate different levels of literacy and development.
A: Broad base, narrow top:
- This characteristic indicates a high birth rate and a large proportion of young individuals in the population.
- It suggests a lower level of literacy and development as there is a larger number of younger individuals who may not have completed their education or have limited access to educational resources.
- This shape is often associated with developing countries with high fertility rates and limited educational opportunities.
B: Broad base, steady slope:
- This characteristic indicates a relatively stable birth rate and a consistent proportion of individuals across different age groups.
- It suggests a moderate level of literacy and development as there is a balance between younger and older individuals in the population.
- This shape is often associated with countries that have made progress in reducing fertility rates and providing educational opportunities.
C: Narrow base, narrow top:
- This characteristic indicates a low birth rate and a smaller proportion of younger individuals in the population.
- It suggests a higher level of literacy and development as there is a smaller number of younger individuals who have likely completed their education or have better access to educational resources.
- This shape is often associated with developed countries with low fertility rates and well-established educational systems.
D: Broad base, broad top:
- This characteristic indicates a high birth rate and a large proportion of both younger and older individuals in the population.
- It suggests a moderate level of literacy and development as there is a mix of younger individuals who may not have completed their education and older individuals who may have limited access to educational resources.
- This shape is often associated with countries experiencing demographic transitions or countries with high fertility rates and limited resources for elderly populations.
Therefore, the characteristic that indicates the lowest levels of literacy and development is A: Broad base, narrow top.

Explanation:
Statement: Many more people live to the south of the Equator than the north.
The statement is false. Here's why:
1. Population distribution:
- The majority of the world's population resides in the Northern Hemisphere.
- The Northern Hemisphere includes densely populated countries like China, India, United States, Russia, etc.
- In contrast, the Southern Hemisphere has a lower population density, with large areas of land being sparsely inhabited.
2. Landmass distribution:
- The Northern Hemisphere has a larger landmass compared to the Southern Hemisphere.
- The Northern Hemisphere includes continents like Asia, Europe, North America, and parts of Africa and South America.
- The Southern Hemisphere consists mainly of water bodies like the Southern Ocean and the Pacific, Atlantic, and Indian Oceans.
3. Climate:
- The Northern Hemisphere has a wider range of climatic zones, including temperate, subarctic, and arctic regions.
- The Southern Hemisphere has a larger proportion of oceanic climates and fewer extreme temperature zones.
4. Economic development:
- The Northern Hemisphere is home to many developed and industrialized countries, contributing to higher living standards and urbanization.
- The Southern Hemisphere includes several developing countries, with lower levels of urbanization and economic development.
In conclusion, the statement that many more people live to the south of the Equator than the north is false. The Northern Hemisphere has a larger population, more landmass, diverse climates, and higher levels of economic development compared to the Southern Hemisphere.

- Other countries in South Central Asia, like India and Pakistan, also have high population densities.
5. Conclusion:
- Based on the analysis, it can be concluded that the statement is true.
- South Central Asia, particularly countries like Bangladesh, India, and Pakistan, have some of the highest population densities in the world.
- However, it's important to note that population density can vary within regions and countries, so specific areas within South Central Asia may have even higher or lower population densities.

Explanation:
To determine if the statement is true or false, we need to compare the population in 1820 and 1999.
- In 1820, the estimated global population was around 1 billion.
- In 1999, the estimated global population was around 6 billion.
Calculation:
- Population in 1820: 1 billion
- Population in 1999: 6 billion
The population in 1999 is 6 times greater than the population in 1820.
Therefore, the statement that the population of the world doubled between 1820 and 1999 is false.

Statement: In the United Kingdom, the birth rate as well as the death rate is low.

Explanation:
To determine if the statement is true or false, let's analyze the birth rate and death rate in the United Kingdom.
Birth Rate:
The birth rate refers to the number of live births per 1,000 people in a population per year. In the United Kingdom, the birth rate has been relatively low compared to other countries. This can be attributed to various factors such as a decreasing fertility rate, changing social attitudes towards having children, and increased access to contraception.
Death Rate:
The death rate, also known as the mortality rate, refers to the number of deaths per 1,000 people in a population per year. In the United Kingdom, the death rate has also been relatively low. This can be attributed to factors such as improved healthcare, advancements in medical technology, and increased awareness about healthy lifestyles.
Conclusion:
Based on the analysis, we can conclude that the statement is true. The birth rate as well as the death rate in the United Kingdom is low compared to other countries.

Analysis:
- The statement claims that Japan and Bangladesh are very densely populated.
- It further suggests that both countries are economically underdeveloped.
- We need to determine whether this conclusion is true or false.
