Economic growth is a fundamental concept in economics that refers to the increase in a country's production of goods and services over time. It is typically measured by the increase in a country's Gross Domestic Product (GDP) or Gross National Product (GNP) over a specific period. Economic growth is a crucial indicator of a country's overall economic health and can lead to higher standards of living, increased employment opportunities, and reduced poverty rates. Researchers studying economic growth often examine factors such as investment, technological innovation, government policies, and international trade to understand the drivers of economic growth and develop strategies to promote sustained growth over the long term.
