While there are a number of different ways to measure economic growth, the best-known and most frequently tracked and reported measure is gross domestic product (GDP).
Gross Domestic Product (GDP), a widely used indicator, refers to the total gross value added by all resident producers in the economy.
Growth in the economy is measured by the change in GDP at constant price.
The Social Progress Index (SPI) measures the extent to which countries provide for the social and environmental needs of their citizens.
Fifty-four indicators in the areas of basic human needs, foundations of well-being, and opportunity to progress show the relative performance of nations.
