Measuring economic growth and identifying emerging economies
Growth is measured by GDP, GDP per capita and the growth rate; emerging economies (BRICS, MINT) are the fast-growing ones.
Economic growth is an increase in the value of goods and services an economy produces. Businesses track it because it signals how fast a country's market is expanding. It is measured with three linked indicators:
- GDP (Gross Domestic Product) — the total value of all goods and services produced in a country in a year. A large or rising GDP means a large, growing market.
- GDP per capita — GDP divided by the population. This is a proxy for average income and living standards, and matters because a country can have a huge GDP (large market) but low GDP per capita (limited spending power per person), or vice versa.
- Economic growth rate — the annual percentage change in GDP. A high growth rate (say 5–7%) signals a rapidly expanding market; a negative rate signals recession.
Emerging economies are economies that are growing and industrialising quickly, moving from low-income towards developed status. They typically have fast GDP growth, rising incomes, a growing middle class and rapid urbanisation, but also less-developed infrastructure and higher political/legal risk than mature economies.
Two common groupings you should know:
- BRICS — Brazil, Russia, India, China and South Africa. Large, fast-growing economies with big populations and rising influence.
- MINT — Mexico, Indonesia, Nigeria and Turkey. A newer grouping of promising emerging economies with young, growing populations.
Not every fast-growing economy is high-income yet, which is exactly why GDP and GDP per capita matter together — GDP shows the size of the opportunity, GDP per capita shows the spending power behind it.
- GDP = total output value; a large/rising GDP = a large, growing market.
- GDP per capita = GDP ÷ population = a proxy for average living standards.
- Growth rate = annual % change in GDP; high rates signal fast-expanding markets.
- Emerging economies grow and industrialise quickly (BRICS, MINT).
- BRICS = Brazil, Russia, India, China, South Africa; MINT = Mexico, Indonesia, Nigeria, Turkey.
