Living standards are a key measure of a country's economic well-being. Real Gross Domestic Product (Real GDP) per head is a widely used indicator of living standards. It represents the average economic output per person in a country and reflects the average level of material well-being.
What is Real GDP per Head?
Real GDP per head is the total value of goods and services produced in a country during a specific period (usually a year), divided by the total population of that country. It is "real" because it is adjusted for inflation, meaning it reflects changes in the actual quantity of goods and services produced, rather than just changes in prices.
The formula for calculating Real GDP per head is:
$$ \text{Real GDP per head} = \frac{\text{Real GDP}}{\text{Population}} $$
Why is Real GDP per Head a good indicator of living standards?
Real GDP per head provides a useful, though not perfect, measure of living standards because:
Higher GDP per head generally means more goods and services are available to people. This includes things like food, housing, healthcare, and education.
It reflects improvements in productivity. Higher productivity means more output can be produced with the same amount of resources.
It can indicate improvements in health and education. A more skilled and healthier workforce contributes to higher GDP per head.
Limitations of Real GDP per Head as an indicator
While a useful indicator, Real GDP per head has limitations:
It doesn't reflect income inequality. A high GDP per head doesn't mean everyone benefits equally. Wealth can be unevenly distributed.
It doesn't account for non-material aspects of well-being. Things like happiness, environmental quality, and social cohesion are not directly measured.
It can be affected by exchange rate fluctuations. Changes in exchange rates can distort comparisons of GDP per head between countries.
It doesn't reflect the quality of goods and services. A higher GDP per head doesn't necessarily mean better quality goods and services.
Trends in Real GDP per Head
Over time, many countries have seen significant increases in Real GDP per head. This is often associated with economic development, driven by factors such as:
Technological advancements: New technologies increase productivity.
Increased investment: Investment in infrastructure and capital goods boosts output.
Improved education and skills: A more skilled workforce is more productive.
Strong economic institutions: Stable and effective institutions create a favorable environment for economic growth.

Conclusion
Real GDP per head is a valuable, though imperfect, indicator of living standards. While it provides insights into economic growth and improvements in material well-being, it's important to consider its limitations and to use it in conjunction with other indicators to get a comprehensive picture of a country's overall development.
