More than 30 percent of the US working-age population is using AI, an increase of three percentage points from the end of 2025. But what does that number mean, and what lessons should we take from it? Today Microsoft released a new report that offers an in-depth look at AI adoption across the United States, allowing for the first time a state- and county-level review. This data and the trends it shows are important.
On a national basis, the US leads the world in AI innovation but ranks just 21st in global AI adoption. Part of the reason for this gap is a clear and uneven pattern of AI adoption across the country. We are also seeing a significant divide between urban and rural counties in AI usage. Usage averages 32.9 percent in metropolitan counties, compared with 16.2 percent in rural areas. In other words, metropolitan usage is about double what we see across rural America.
The study also shows that another powerful driver of AI diffusion is the presence of colleges and universities. Counties with higher shares of residents aged 18 to 24 have significantly higher AI usage rates—28.6 percent compared with 20.3 percent in other counties. And while college students are some of the most vocal about the risks of AI, they are also helping lead adoption. In counties with college towns like Williamsburg, Virginia, and Story, Iowa, we see usage rates that rival the highest in the world.
