What is the difference between nominal GDP and GDP per capita?

Nominal GDP is the total market value of goods and services a country produces in a year, in current US dollars. GDP per capita divides that total by the population, giving an average economic output per person, which is a rough proxy for living standards.

Why is GDP measured in US dollars here?

Converting every economy to a common currency, usually the US dollar at market exchange rates, lets you compare countries directly. This is nominal GDP; purchasing-power-parity GDP would adjust for local price levels and is a separate measure.

Which countries have the largest economies?

The United States and China are by far the two largest economies, followed by Germany, Japan and India. Rankings shift year to year with growth rates and exchange-rate moves.

Why can a rich country have a small total GDP?

GDP per capita can be very high in small wealthy states like Switzerland or Singapore even though their total GDP is modest, simply because they have few people. Total GDP rewards both productivity and population size.

How current are these GDP figures?

They are approximate recent annual estimates rounded for readability. GDP data is revised repeatedly and moves with exchange rates, so use these for relative comparison rather than as exact accounting figures.

Country GDP reference

This reference shows two core economic indicators for major countries: nominal GDP in US dollars (the size of the whole economy) and GDP per capita (output per person). Together they let you compare both economic weight and average prosperity at a glance.

How it works

Each country carries a nominal GDP figure in US dollars and a population. The tool derives per-capita GDP directly:

gdp_per_capita = nominal_gdp_usd / population

Nominal GDP uses current market exchange rates, so it reflects both real output and currency strength. Sorting by total GDP ranks the heavyweight economies; sorting by per capita re-orders the list toward small, wealthy states. The two views often disagree sharply — a reminder that economic size and individual prosperity are different things.

These are rounded recent annual estimates. GDP is revised frequently and is sensitive to exchange-rate swings, so the reference is for ranking and magnitude, not precise national accounts.

Tips and example

The United States (~25–28 trillion USD) and China (~18 trillion USD) dwarf all other economies in total size.
A populous country like India can rank among the top economies by total GDP while having a comparatively low per-capita figure, because the total is spread across 1.4 billion people.
Small wealthy states such as Switzerland or Singapore rank high on per-capita GDP despite modest total output — sort both ways to see the contrast.
For investment or policy work, pair this with PPP GDP and use up-to-date IMF or World Bank releases.
