## How to read this

Country is the buyer's stated location, not where the work is done. Figures come from public project briefs from December 2025 to November 2026 and show what briefs offered, not what was paid. Hourly briefs are estimated from rate, length and workload. Countries need 30 priced briefs to be ranked, and are left out of rankings when one buyer makes up over a quarter of briefs. Counts under 5 are hidden. Population and GDP per person are the latest World Bank figures.
