National Income and Poverty Measurement

Per capita income (average income per person) is the most reliable indicator of changes in standard of living. It reflects actual purchasing power and economic well-being of individuals better than price indices or currency values, which can be influenced by external factors.

The poverty line in India is traditionally measured based on caloric consumption - specifically 2400 calories per person per day in rural areas and 2100 calories in urban areas. This nutritional standard determines the minimum income required to purchase basic food needs. The other options (dwelling houses, employment nature, education level) are not the primary criteria used for defining poverty line.

Per capita income at constant prices best reflects changes in standard of living because it adjusts for both population growth and inflation. Current prices include inflation effects. GNP and national income are aggregate measures, not per capita.

Economic prosperity is measured by real GNP (Gross National Product) at fixed prices, which removes inflation effects and shows actual growth in output. Current prices would be misleading as they include inflation. Real GNP reflects genuine increase in goods and services produced.

Economic growth is primarily measured in terms of national income (GDP/GNP). An increase in national income indicates expansion of the economy's productive capacity and output. Urban employment, rural development, and balance of payments are specific aspects, not comprehensive measures.

NNP (Net National Product) is calculated as GNP (Gross National Product) minus depreciation. GNP is the total value of all final goods and services produced by a country's residents in a year, and depreciation represents the wear and tear or capital consumption during production. NNP gives us the net value after accounting for this capital consumption.

In India's national income accounting, National Income refers to NNP (Net National Product) at factor cost. This is because NNP at factor cost represents the total income earned by factors of production (land, labor, capital, entrepreneurship) within the economy, which is the true measure of national income.

GDP stands for Gross Domestic Product, which measures the total monetary value of all goods and services produced within a country's borders in a specific time period. It is a key indicator of economic health. The other options mix unrelated terms - 'Development' and 'Project' are not standard economic acronyms.

National Income equals GNP at market prices minus depreciation, then adjusted for indirect taxes (subtract) and subsidies (add). This represents the net value of goods and services produced. Option B incorrectly subtracts net factor income from abroad (that's for NNP), and Option D adds factor income instead of adjusting for taxes/subsidies.

NNP (Net National Product) represents national income, calculated as GNP minus depreciation. National income accounting defines NNP at factor cost as the true measure of a country's national income.

Pensions are included in National Income calculations as they represent transfer payments from one section of society to another. While transfer payments don't create new goods or services, they are part of the national income accounting system. Services of housewives, smugglers' income, and watchmen's income are excluded for various reasons - some being non-market activities or illegal.

GNP (Gross National Product) is considered the best measure of economic growth because it includes net factor income from abroad (remittances, profits from foreign investments, etc.), giving a more complete picture of a nation's economic welfare. GDP only measures domestic production. Net revenue and tax revenue are fiscal indicators, not comprehensive growth measures.

The Big Mac Index is an informal tool published by The Economist to measure purchasing power parity (PPP) between two currencies by comparing the price of a Big Mac burger.

The Consumer Price Index (CPI) measures the average change over time in the prices paid by urban consumers for a market basket of consumer goods and services.

GDP is 'gross' because it does not account for the wear and tear of capital assets used in production, known as depreciation. Net Domestic Product (NDP) is calculated by subtracting depreciation from GDP.
