Decision-making has become the single largest category of workplace artificial intelligence activity, accounting for 28 percent of usage, according to Microsoft Work Trend Index data visualized by Visual Capitalist. The analysis draws on more than 100,000 Microsoft 365 Copilot conversations examined globally in February 2026.

The findings indicate workplace AI has moved beyond simple productivity tasks. Within the broader category of analyzing, reasoning, and deciding, decision-making leads at 27.5 percent of activity, followed by data analysis at 5.5 percent, creative thinking at 4.9 percent, and information processing at 3.1 percent. Quality assessment and compliance review account for 2.8 percent and 2.5 percent respectively.

Information gathering represents another major block of usage, with getting information alone making up 13 percent of workplace AI activity. Documentation accounts for roughly 12 percent, while team communication represents 8.4 percent.

The same data set shows wide geographic variation in adoption. Within the United States, the District of Columbia leads with 40.3 percent of working-age residents using AI, followed by Maryland at 36.3 percent and Utah at 35.7 percent. Microsoft estimates 32.9 percent of metro-county residents use AI nationwide. Williamsburg, Virginia recorded the highest local adoption rate in the country at 73.2 percent, a figure attributed to its university and research community.

Globally, 17.8 percent of working-age adults now use AI regularly, with the United Arab Emirates leading at 70.1 percent and Singapore second at 63 percent.
