<h3>What is economic growth ?</h3>
Economic growth can be regarded as a rise in the production of goods and services on a comparative basis between two periods of time. Either nominal or real measurements are acceptable. Gross national product (GNP) or gross domestic product (GDP) are the most popular measures to measure total economic growth, however alternative metrics are sometimes used.An rise in an economy's overall output, which is often represented in an increase in national income, can be summed up as economic growth. Increases in average marginal productivity are typically, but not always, correlated with increases in overall production. As a result, there is an increase in income, which encourages people to spend more money and buy more goods, raising the level of living and quality of life in tangible terms.
