Software engineering leads almost everywhere, the US uses Claude most, and the data are released openly. ## Source excerpt That doesn’t mean these are the most popular tasks: software engineering is still by far in the lead in almost every state and country in the world. Instead, it means that people in Massachusetts have been more likely to ask Claude for help with scientific research than people elsewhere – or, for instance, that Claude users in Brazil appear to be particularly enthusiastic about languages: they use Claude for translation and language-learning about six times more than the global average. These are statistics we found in our third Anthropic Economic Index report . In this latest installment, we’ve expanded our efforts to document the early patterns of AI adoption that are beginning to reshape work and the economy. We measure how Claude is being used differently… We summarize the report below. In addition, we’ve designed an interactive website where you can explore our data yourself. For the first time, you can search for trends and results in Claude.ai use across every US state and all occupations we track, to see how AI is used where you live or by people in similar jobs. Finally, if you’d like to build on our analysis, we’ve made our dataset openly available , alongside the data from our previous Economic Index reports. We've expanded the Anthropic Economic Index to include geographic data. Below we cover what we've learned about how Claude is used across countries and US states. The US uses Claude far more than any other nation. India is in second place, followed by Brazil, Japan, and South Korea, each with similar shares. However, there is huge variation in population size across these countries. To account for this, we adjust each country’s share of Claude.ai use by its share of the world’s working population. This gives us our Anthropic AI Usage Index , or AUI. Countries with an AUI greater than 1 use Claude more often than we’d expect based on their working-age population alone, and vice-versa. From the AUI data, we can see that some small, technologically adva ## About this publication **Lab or institute research, not peer reviewed.** A report or blog post published by an AI lab or research institute on its own site.
