Correct Option
The correct option is 2 only
Explanation
The population of the world is unevenly distributed across the globe. This unevenness is often summarized by the observation that "Asia has many places where people are few and few places where people are many." Understanding the spatial pattern of population density and distribution is fundamental to demography.
Statement-wise Analysis
- Statement 1 is Incorrect: It is a standard demographic fact that the distribution of the human population is highly skewed. Broadly, 90 % of the world's population lives in about 10 % of its land area. The remaining land area is either sparsely populated or uninhabited due to harsh climatic or geographical conditions.
- Statement 2 is Correct: The ten most populous countries of the world contribute approximately 60 % of the world’s population, not 80 %. While these countries hold a majority, the figure 80 % is an exaggeration.
- Statement 3 is Incorrect: Of the ten most populous countries, six are located in Asia, not four. These Asian nations typically include China, India, Indonesia, Pakistan, and Bangladesh, along with Russia (which is transcontinental but geographically holds a vast area in Asia) or Japan (in historical data contexts).
Key Takeaway
Global Population Skew: The world's population is concentrated in a very small percentage of habitable land, with the continent of Asia dominating the list of the most populous nations (hosting 6 out of the top 10).
