The correct option is 1 and 3 only.
Explanation
Gross Domestic Product (GDP) is the total monetary value of all final goods and services produced within the domestic territory of a country during a specific time period, usually a year. It serves as the primary indicator of the economic size and health of a nation.
Statement-wise Analysis:
- Statement 1 is Correct: GDP is the standard measure used to quantify the aggregate economic activity of a nation. It reflects the overall size of the economy; for instance, India is often described as a $3 trillion economy based on its nominal GDP.
- Statement 2 is Incorrect: GDP is calculated by summing the value of final goods and services only. Intermediate goods (goods used to produce other goods) are excluded to avoid the error of double counting, as the value of intermediate inputs is already included in the final price of the product.
- Statement 3 is Correct: GDP is a territorial concept. It measures production taking place strictly within the geographic boundaries of the country. Economic activities performed by Indian nationals abroad are excluded from India's GDP (though they are included in the Gross National Product, or GNP).
Key Takeaway:
GDP focuses on where production takes place (domestic territory) and counts only final goods, whereas GNP focuses on who produces it (nationals) and includes net factor income from abroad.
