Quick Overview
What are living standards?
A measure of people's quality of life in a country, including health, education, income, and access to services.
How do we measure them?
Single indicators (like GDP per capita) or composite indicators (like HDI which combines health, education, and income).
Why do they differ?
Economic systems, government policies, corruption, education, taxation, population size, inflation, and regional differences all play a role.
Indicators of Living Standards
Real GDP Per Capita: The Basics
Before we can understand GDP per capita, we need to know the difference between three related terms:
Nominal GDP is the actual value of all goods and services produced in a country in one year. It hasn't been adjusted for inflation—it's just the raw number at current prices. If a country produces £100 billion worth of goods, that's the nominal GDP.
Real GDP is nominal GDP adjusted for inflation. This is crucial because inflation makes prices go up, but that doesn't mean the economy actually grew. If inflation was 10% and nominal GDP rose from £100bn to £110bn, the real growth was only £0bn in real terms—prices just got higher.
GDP per capita takes real GDP and divides it by the population. So if a country's real GDP is £1 trillion and it has 100 million people, the GDP per capita is £10,000. This shows the average wealth per person.
Why is real GDP per capita useful?
It allows us to compare living standards between countries fairly. Switzerland has a much higher GDP per capita than Burundi, which tells us that on average, people in Switzerland have more resources available to them than people in Burundi.
But here's the catch—and this is important:
- It's an average. A country could have a high GDP per capita while many people live in poverty. Imagine a country where one billionaire and 99 poor people live together—their average income looks decent, but most people are poor.
- It's only one number. GDP per capita tells you nothing about health, education, environmental quality, or happiness. It's a very limited picture.
- It ignores inequality. Two countries with the same GDP per capita could have very different wealth distributions. One could be fairly equal; the other could have extreme rich-poor divides.
📌 Exam Trick: When you see "at constant prices" in an exam question, it means real GDP. If a question says "GDP rose at constant prices," it means real growth happened—not just inflation.
📋 Practice Question 1
A country's nominal GDP increases from £200 billion to £230 billion in one year. Inflation during that year was 15%. Calculate the real GDP for both years and explain what the change in real GDP tells us.
