Total output divided by the number of people
This is the country entire yearly output shared out equally on paper. It is a per-head average, not what any real person earns. Norway made about 606 billion dollars in a recent year across 5.5 million people, which is roughly 110,000 dollars each. To go the other way, multiply per-person output by the population to recover the total.
Nominal, PPP and real are three different numbers
The same country can look richer or poorer depending on which version you use, so a figure only means something once you know which one it is.
| Version | What it adjusts for | Best used for |
|---|---|---|
| Nominal | Current market exchange rates | Comparing currency-value size |
| PPP | Local cost of living | Comparing real living standards |
| Real | Inflation over time | Comparing one year against another |
PPP matters most for lower-cost economies: China roughly doubles from 12,500 nominal to 23,800 at PPP, and India rises from about 2,500 to 9,200, because everyday goods are much cheaper there.
Where countries land
| Country | Nominal (per person) | PPP (per person) |
|---|---|---|
| Luxembourg | $125,600 | $144,000 |
| Singapore | $88,100 | $101,600 |
| United States | $85,000 | $85,000 |
| Germany | $59,500 | $70,400 |
| China | $12,500 | $23,800 |
| India | $2,500 | $9,200 |
| Burundi | $290 | $1,400 |
The global median is around 11,000 to 12,000 dollars, so half the world lives in countries below that line. The top of the table is dominated by small nations and city-states.
What the number leaves out
- Distribution. It is an average. A country at 50,000 dollars with high inequality can leave the typical person worse off than one at 40,000 dollars with income evenly spread.
- Non-market work and harm. Housework and childcare do not count toward it, while pollution and resource depletion are not subtracted.
- Quality of life. Health, education, safety and free time are missing. Qatar is near the top on money yet scores far lower on wellbeing than lower-ranked Denmark.
Common questions
How is GDP per person calculated?
Divide a country total gross domestic product by its population. If GDP is 1 trillion dollars and 50 million people live there, GDP per person is 20,000 dollars a year.
What is the difference between nominal and PPP GDP per person?
Nominal uses current exchange rates. PPP adjusts for how far money goes locally. China is about 12,500 dollars nominal but roughly 23,800 dollars at PPP, because most goods cost far less there. Use PPP to compare living standards and nominal to compare currency value.
Why is a high GDP per person not the same as being well off?
It is an average, so a small rich minority can pull it up while most people earn much less. It also ignores how income is shared, unpaid work, and pollution. Median income and the Human Development Index give a fuller picture.
