Key Takeaways
- New York, Massachusetts, and California lead in Claude usage relative to their working-age populations.
- Washington, D.C. is the strongest outlier overall, while neighboring Maryland shows much lower uptake.
- West Virginia ranks last on the index, alongside Mississippi and Kentucky.
AI usage is spreading quickly across the U.S., but adoption isn’t happening evenly.
New data from Anthropic reveals which states use its Claude chatbot the most relative to their working-age populations, based on the Anthropic AI Usage Index.
The results show that while large states like California dominate total usage, smaller states and tech hubs often have the highest adoption intensity.
New York And California Lead in Claude Usage
Dive into the data below, collected during the week of Nov. 13–20, 2025.
Each score represents usage relative to what would be expected based on a state’s working-age population.

New York has the highest Anthropic AI Usage Index among U.S. states at 2.68x relative to its working-age population. California, however, accounts for the largest share of total Claude usage at 17.58%, with New York close behind at 15.74%.
This contrast highlights the difference between total usage and usage intensity. While California generates the most activity overall due to its size, New York shows higher adoption relative to its workforce.
Washington, D.C. stands out as the strongest outlier, with an index value of 4.00x. The capital’s high concentration of professionals and government workers likely contributes to this elevated adoption. Neighboring Maryland, by comparison, records a much lower index of 1.05x, though it still ranks near the top nationally.
At the other end of the spectrum, West Virginia has the lowest index at 0.25x, followed by Mississippi (0.29x) and Kentucky (0.38x). These results highlight the uneven pace of AI adoption across the country.
Many of the leading states are concentrated along the West Coast and in the Northeast, regions known for strong technology sectors, major financial institutions, and highly educated workforces.
Massachusetts, for example, ranks second on the index at 1.60x and is home to institutions like the Massachusetts Institute of Technology. California, where Anthropic is headquartered, follows at 1.48x and hosts universities such as Stanford, Caltech, UC Berkeley, and UCLA.
Given these ecosystems, it’s unsurprising that common Claude use cases include academic work, web and app development, and business planning.
AI’s True Impacts Are Difficult To Track
Anthropic positioned its data release as a way to better understand AI’s broader economic impact.
JPMorgan attributed 1.1% of total GDP growth in the first half of 2025 to AI-related capital expenditures. While the technology has already contributed to breakthroughs in healthcare and medicine, other analyses paint a more mixed picture.
For example, Goldman found limited near-term boosts to the economy, and debate continues over AI’s long-term effects on productivity and the workforce.
