Lesson 75 - Economic Growth
Economic growth is the increase in the value of goods and services an economy produces over time. It is usually measured as growth in real GDP, adjusted for inflation. Growth matters because it raises living standards, creates jobs, and gives governments resources to fund education, healthcare, and infrastructure. But growth also raises questions about sustainability and inequality. This lesson explains what drives growth, how it is measured, and why it matters for individuals, businesses, and governments.
What is economic growth?
At its core, economic growth is about producing more output with the same or more resources. If a country produces more cars, software, and food this year than last, it has grown. Growth is most often expressed as the annual percentage change in GDP. Real growth removes the effects of inflation, showing true increases in volume of goods and services.
Table: Sources of economic growth
Graph 1: Global GDP growth rates
The chart shows average annual global GDP growth in different decades, highlighting long-term trends.
Growth was higher in the 1960s and 2000s, but slowed after the 2008 crisis.
Graph 2: GDP per capita comparison
Economic growth per person (GDP per capita) better shows changes in living standards. This chart compares GDP per capita in 2022 for selected countries.
Wealthier nations have higher GDP per capita, but growth in emerging markets is faster.
Story: The rise of South Korea
In the 1960s, South Korea was poorer than many African nations. Through decades of investment in education, manufacturing, and technology, it grew into a high-income country. Today, it is home to global companies like Samsung and Hyundai. This story shows how growth driven by policy and innovation can transform a nation’s fortunes within a few generations.
Why growth matters for you
Growth influences wages, job opportunities, and investment returns. A growing economy creates new businesses and technologies, which improve your quality of life. It also supports government finances, which fund services you use. However, growth that is too fast can create bubbles, while growth that ignores inequality or the environment can be unsustainable. Thinking about growth means thinking about both opportunity and risk.
Summary
- Economic growth is measured as real GDP growth, showing increases in output.
- Main drivers are labor, capital, technology, and institutions.
- Charts show global trends and GDP per capita comparisons.
