The term describes an increase in the inflation-adjusted market value of the goods and services produced by an economy over a period of time. It is conventionally measured as the percentage rate of increase in real gross domestic product (GDP), or real GDP per capita. For example, a country experiencing it might see its total output of goods and services rise from \$1 trillion to \$1.03 trillion in a year, representing a 3% increase.
Its importance lies in its potential to improve living standards, reduce poverty, and enhance a nation’s overall well-being. Historically, sustained periods of it have been associated with advancements in technology, increased investment in human capital, and improved institutional frameworks. These developments contribute to a more productive and prosperous society.
