The database compiles national accounts and other statistics for about 200 economies. The wiki uses the constant-price GDP per person series, retrieved on 22 October 2026, for the national table in What GDP Leaves Out. Values for 2025 are first estimates and may be revised. The series measures the flow of output per person and carries none of the household measures set beside it in that table.
