Anthropic AI Usage Index
The Anthropic AI Usage Index (AUI) measures whether Claude is over- or underrepresented in a geography relative to that geography’s working-age population.
Key points
- An AUI above 1 means a country or region uses Claude more intensively than its share of working-age population would predict; below 1 means lower-than-expected usage [src-069].
- Global Claude.ai usage remains uneven and strongly associated with GDP per capita [src-069, src-070].
- At country level, a 1% increase in GDP per capita is associated with a 0.7% increase in Claude usage per capita [src-069].
- Within the US, workforce composition matters more than income: states with more computer and mathematical workers tend to have higher usage [src-069].
- US state-level usage became more evenly distributed from August to November 2025, with a cautious 2-5 year convergence estimate if the pattern persists [src-069, src-070].
- Globally, there was no clear sign of low-use countries catching up or high-use countries pulling away [src-069].
- Anthropic’s public summary adds a use-case interpretation: lower-income countries skew toward educational coursework, while higher-income countries show more work and personal use [src-070].
- The March 2026 report updates the convergence picture: US state-level usage kept converging, but the equalization estimate slowed from 2-5 years to 5-9 years [src-071].
- Across countries, usage became slightly more concentrated: the top 20 countries’ share of population-adjusted usage rose from 45% to 48% [src-071].
