GDP Explained: What It Measures and What It Misses

Gross domestic product is the headline measure of economic activity. It is useful but has limitations.

By Felix Narayan | Oct 15, 2026 | 4 min

Gross domestic product, or GDP, measures the total value of goods and services produced in an economy over a period.

It is widely used to compare economies and track growth, but it does not capture everything that matters for wellbeing.

I How it is measured

GDP can be calculated in three ways: production, income, and expenditure. In theory, all three should give the same result.

II Real vs nominal

Nominal GDP uses current prices. Real GDP adjusts for inflation, making comparisons over time more meaningful.

III Per person

GDP per capita divides GDP by the population.

IV Limitations

— Excludes unpaid work such as caring
— Does not measure inequality
— Ignores environmental damage
— Does not capture quality of life directly

V Alternatives

Economists and governments also use measures such as median income, wellbeing indicators, and environmental accounts.
