Economic Growth Fundamentals

Economic growth happens when a country's economy expands over time, measured as the percentage change in GDP (Gross Domestic Product) from one year to the next. Think of GDP as the total value of everything produced in a country - from smartphones to haircuts to university courses.

When economists talk about national income, they're referring to this total economic output. There's also GNP (Gross National Product), which includes everything owned by a country's firms, even if they're operating abroad. Both help us track how well an economy is performing.

Growth doesn't happen in a straight line - it goes up and down in what's called the business cycle. This pattern of expansion and contraction is completely normal, though understanding it helps predict future economic conditions.

Key Insight: Economic growth directly impacts your standard of living - more growth typically means better job opportunities, higher wages, and improved public services.
