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