What this dot point is asking

OCR wants you to define economic growth, explain how it is measured using GDP and GDP per capita, identify the determinants of growth, and describe the economic cycle. You must also be able to calculate GDP per capita and interpret growth data.

What economic growth means

Real GDP strips out inflation so that growth reflects more goods and services, not just higher prices. A rise in real GDP means the economy is genuinely producing more.

Measuring growth: GDP and GDP per capita

For example, GDP of £2,000\pounds 2{,}000 billion shared among 50 million people gives £2,000,000 million50 million=£40,000\frac{\pounds 2{,}000{,}000\text{ million}}{50\text{ million}} = \pounds 40{,}000 per person.

The determinants of growth

Several factors drive long-run economic growth by raising the economy's productive capacity:

  • Investment in new capital (machines, infrastructure) raises productivity.
  • Technology lets the same inputs produce more output.
  • Size and skill of the workforce (more workers, better education and training).
  • Natural resources (discovering oil or minerals adds to capacity).
  • Government policy (supply-side policies, stability, good institutions).

These map onto raising the quantity and quality of the factors of production, which expands the economy's productive potential.

The economic cycle

Growth is not steady; real economies move through the economic cycle (also called the business cycle):

  • Boom: fast growth, low unemployment, but rising inflation as demand is high.
  • Slowdown: growth slows from its peak.
  • Recession: output falls (technically, two consecutive quarters of falling real GDP); unemployment rises.
  • Recovery: output starts rising again towards the long-run trend.

The government uses policy to smooth the cycle, supporting demand in a recession and cooling it in a boom.

Q1. Define economic growth. [2 marks]

  • Cue. An increase in the output of goods and services, measured by the rise in real GDP.

Q2. A country's GDP is £600\pounds 600 billion and population 30 million. Calculate GDP per capita. [2 marks]

  • Cue. 600,000 million30 million=£20,000\frac{600{,}000\text{ million}}{30\text{ million}} = \pounds 20{,}000 per person.

OCR J205/02 20204 marksA country's GDP is £800\pounds 800 billion and its population is 40 million. Calculate GDP per capita, then state what happens to it if GDP rises to £880\pounds 880 billion with the same population.
Show worked answer →

A Calculate question. GDP per capita is GDP divided by population: £800,000 million40 million=£20,000\frac{\pounds 800{,}000\text{ million}}{40\text{ million}} = \pounds 20{,}000 per person.

If GDP rises to £880\pounds 880 billion with the same population: £880,000 million40 million=£22,000\frac{\pounds 880{,}000\text{ million}}{40\text{ million}} = \pounds 22{,}000 per person. GDP per capita rises from £20,000\pounds 20{,}000 to £22,000\pounds 22{,}000, a rise of £2,000\pounds 2{,}000 (10%).

Markers reward the correct division for both figures and the statement that GDP per capita rose. Keeping the units consistent (billions and millions) is the key skill.

OCR J205/02 20226 marksDiscuss the costs and benefits of economic growth for a country.
Show worked answer →

A 6 mark evaluative question.

Benefits: higher growth means higher incomes and living standards, more jobs, and more tax revenue for public services without raising tax rates.

Costs: growth can cause inflation if demand outpaces supply, environmental damage from more production and pollution, and wider inequality if the gains are unevenly shared, harming sustainability. Markers reward developed points on both sides and a judgement, for example that growth raises living standards but must be managed to limit environmental and inequality costs (the idea of sustainable growth).
