What it shows
- 2025: common observation year
- 186: economies with both inputs
- GDP / people: documented ratio model
GDP per person is an output ratio, not household income or a welfare score. Derived ratios and both model inputs are included so agents can inspect the calculation.
Method
Use positive, nonmissing GDP and population in the same year; exclude all aggregates. Ratio uses current US dollars, not PPP or constant prices. Grey means unmatched or missing map coverage.
The collection bundle includes models/economic-scale-model.json with reusable derived results and stable source identifiers.
