description: "Anthropic’s second Economic Index report examines how Claude.ai usage changed after Claude 3.7 Sonnet launched, using 1 million anonymized Free and Pro conversations from the following 11 days. Clio maps conversations to 17,000 tasks in the U.S. Department of Labor’s O*NET database, enabling comparisons across occupations and interaction modes, while the report also introduces a 630-category bottom-up taxonomy. Coding, education, and science usage increased modestly, and extended thinking appeared most often in technical and creative work, including computer science research, software development, multimedia art, and video game design. Augmentation remained 57% of usage, learning interactions rose from about 23% to 28%, and the report releases task- and occupation-level datasets covering thinking mode and augmentation-versus-automation patterns."

## Summary

Anthropic’s second Economic Index report examines how Claude.ai usage changed after Claude 3.7 Sonnet launched, using 1 million anonymized Free and Pro conversations from the following 11 days. Clio maps conversations to 17,000 tasks in the U.S. Department of Labor’s O\*NET database, enabling comparisons across occupations and interaction modes, while the report also introduces a 630-category bottom-up taxonomy. Coding, education, and science usage increased modestly, and extended thinking appeared most often in technical and creative work, including computer science research, software development, multimedia art, and video game design. Augmentation remained 57% of usage, learning interactions rose from about 23% to 28%, and the report releases task- and occupation-level datasets covering thinking mode and augmentation-versus-automation patterns.

## Context

The report aims to understand AI’s effects on labor markets and the economy over time, while examining changes in Claude.ai usage after the launch of Claude 3.7 Sonnet.

## Approach / What changed

The analysis covers 1 million anonymized Claude.ai Free and Pro conversations from the 11 days after launch. Clio maps conversations to 17,000 O\*NET tasks, and the report adds a 630-category bottom-up usage taxonomy plus datasets on thinking mode and augmentation versus automation.

## Takeaways

- Clio maps Claude.ai conversations to tasks in the U.S. Department of Labor’s 17,000-task O\*NET database, supporting analysis by occupation and interaction mode.
- Extended thinking was used most often for technical and creative tasks; associated usage reached about 10% for computer and information research scientists and about 8% for software developers.
- Augmentation accounted for 57% of usage, while learning interactions increased from about 23% to 28%; no high-level occupational category was dominated by automation.
