Anthropic Economic Index Report on AI Usage

The Anthropic Economic Index Report provides a detailed analysis of AI usage metrics, focusing on the interactions with Claude in November 2025. It introduces new economic primitives that measure AI's impact across five dimensions: user and AI skills, task complexity, autonomy, success rates, and usage purposes. The report reveals geographic variations in AI adoption, with notable findings that the US, India, Japan, the UK, and South Korea lead in usage. It also discusses changes since the previous report, highlighting that Claude usage is increasingly concentrated on specific tasks, particularly in coding. The report emphasizes the uneven global adoption of AI, correlating it with GDP per capita, and notes a trend towards more equitable usage across US states. The findings suggest that AI's economic impact is significant, with implications for job exposure and productivity, and aim to facilitate a better understanding of AI's transformative effects on the economy.
