Description

A measurement strategy that infers the share of an area's ChatGPT activity tied to school from the ratio of average activity while school is in session to average activity in the summer. As the article states, "Educational AI usage is measured as the ratio of average activity while school is in session to average activity in the summer." Validation exercises test whether the measure tracks school calendars, whether college students drive it, and its year-to-year reliability. It serves as the treatment variable in cross-metro test-score analyses.

• College students contribute to but cannot fully explain the summer dip in ChatGPT activity [~M]
• The educational summer dip is invisible in aggregate 2025 ChatGPT activity due to rapid overall growth, even though the school-calendar response remains intact [+W]
