The question asks for the correct formula for per capita income. Per capita income is a measure of the average income earned per person in a given area (city, region, country) in a specified year. It is calculated by dividing the total income of an area by its total population.
B) Per Capita Income = National Income divided by Total (mid-year) Population
This is the standard and correct formula used in economics to calculate per capita income. It represents the average income per person in a country for a given period.
\[ \text{Per Capita Income} = \frac{\text{National Income}}{\text{Total Population}} \]The question asks about the primary use of per capita income as an indicator. We need to understand the definition of per capita income and what it represents in economic terms.
D) The average standard of living or average income level of a country's population. Per capita income directly measures the average income available per person, which is a key determinant and indicator of the average standard of living in a country.
The question asks about a major criticism of using per capita income as a measure of the standard of living for a typical citizen. We need to identify the option that highlights a significant limitation of this economic indicator.
A) Ignores how income is actually distributed among the population, so a country with very unequal income distribution could show a high average even if most people remain poor — This is the most significant criticism. Per capita income is an average and does not provide information about how wealth is distributed. A country could have a high per capita income due to a small number of very wealthy individuals, while the majority of its citizens live in poverty. Therefore, it fails to represent the standard of living for a "typical" citizen in such scenarios.
This question tests the understanding of per capita income, which is a fundamental economic indicator. Per capita income is calculated by dividing the total national income by the total population. We need to compare two countries with identical total national income but different population sizes.
A) A higher per capita income, since the same total income is divided among fewer people
This statement correctly explains that if the total national income is the same, a smaller population will result in a higher per capita income because the fixed income is distributed among fewer individuals.
To determine the effect on per capita income when population grows faster than national income, we need to understand the definition of per capita income and how it relates to national income and population. We will use a simple formula to analyze the relationship.
C) Grow more slowly than national income, and could even decline, despite national income itself rising. This option accurately describes the outcome when population growth outpaces national income growth. The per capita income, being a ratio, will decrease if the denominator grows faster than the numerator, or increase at a slower rate if both are growing but the denominator's growth is significantly higher.
The question asks why India's per capita income is relatively moderate despite a large total national income. This requires understanding the definition of per capita income and how it relates to total national income and population.
D) India's very large population, which means a large total national income is divided among an exceptionally large number of people, lowering the average figure
This option correctly explains the phenomenon. India has the second-largest population in the world (and recently surpassed China as the most populous). When a large total national income is distributed among such a massive population, the per capita (per person) share naturally becomes smaller, leading to a moderate per capita income figure despite a high overall GDP.
