Microsoft AI Economy Institute estimates, republished by Our World in Data with ISO3 codes. 147 countries, all three periods. IMPORTANT: values are modelled, and low-data countries are imputed in regional blocks — 12 West African countries share exactly 10.1% and the four Guianas share exactly 10.3%. Rank movements inside those blocks are artefacts of the model, not independent national trends.

CSET estimates. 119 countries appear across 2016–2025, fewer in any single year. Absolute totals, not population-adjusted — small economies rank low by construction.

Epoch AI. Only ~35 countries have ever produced a notable model, and the United States and China dominate. Most of the map is legitimately no-data. Models credited to several countries count once for each.

190 countries appear across 2016–2024, fewer in any single year — the header above counts the latest year only. Best coverage in the project. Includes Kosovo, which OWID codes as OWID_KOS and which has no ISO numeric — it appears in tables and rankings but cannot be picked on the globe.
