How global income percentiles work
Read the WO-PPP world curve without averaging country rankings.
By RankMyIncome · Updated 22 October 2026
A separate distribution
The world comparison uses the imported WID WO-PPP curve directly. It is not an average of country percentiles, and countries are not treated as equal-weight observations by this calculator. A global reference distribution describes a different population from any one national curve.
From local income to world income
Divide the local annual amount by the country’s stored PPP factor. Apply the original percentile function to that common-unit amount and the world thresholds. Two inputs that become the same USD PPP amount have the same global rank, even when their national ranks differ.
Read the date and definition
The imported world series is dated 2024. The income concept remains pre-tax national income for equal-split adults aged 20+. It is not an employee-only wage comparison or a wealth ranking. Its top percentage does not measure financial security or the cost of living in every city.
Interpret surprising differences
A modest national position can coexist with a high global position when the national distribution sits higher than much of the world curve. Neither result cancels the other. Outside-range world inputs are marked as extrapolations. Explore world thresholds and local equivalents and read why the two ranks differ. Compare years and concepts before interpreting small changes.
