GNI per capita, PPP (current international $)

Definition

This indicator provides values for gross national income (GNI) per person expressed in current international dollars, converted by purchasing power parities (PPPs). PPPs account for the different price levels across countries and thus PPP-based comparisons of economic output are more appropriate for comparing the output of economies and the average material well-being of their inhabitants than exchange-rate based comparisons. Gross national income is the total income earned by all residents within an economic territory during an accounting period. It is equal to gross domestic product plus earned income receivable from abroad minus earned income payable abroad. The core indicator has been divided by the general population to achieve a per capita estimate. This series has been linked to produce a consistent time series to counteract breaks in series over time due to changes in base years, source data and methodologies. Thus, it may not be comparable with other national accounts series in the database for historical years. This indicator is expressed in current prices, meaning no adjustment has been made to account for price changes over time. The PPP conversion factor is a currency conversion factor and a spatial price deflator. PPPs convert different currencies to a common currency and, in the process of conversion, equalize their purchasing power by eliminating the differences in price levels between countries, thereby allowing volume or output comparisons of GDP and its expenditure components.

Methodology for Economy indicators

Economic indicators measure the size, structure, and dynamics of a country's economy. The World Bank collects data from national statistical offices, central banks, and the IMF, then normalizes it for cross-country comparison. Watch out for nominal versus real (inflation-adjusted) values: nominal figures in current US dollars are sensitive to exchange rate swings, while constant dollar series isolate real growth. Most macro indicators have a 1–2 year reporting lag.

How to interpret

• Always check the unit and reporting year before comparing values across countries.
• NULL or "Not available" means the World Bank did not publish a value — we never estimate.
• Year-over-year changes can be driven by methodology updates, not just real economic shifts.
• This indicator is in current US dollars. Compare with the constant-dollar variant (if available) to isolate real growth from inflation and currency effects.
