NBER – How People Use ChatGPT

The document explores the use of the chatbot ChatGPT from its launch in November 2022 to July 2025.

Key findings include that ChatGPT was adopted by about 10% of the world's adult population. Initial users were predominantly male, but the gender gap has significantly narrowed. Higher growth rates are observed in low-income countries. There is a steady increase in work-related messages, but an even faster growth in non-work-related messages, which have risen from 53% to over 70% of total usage. The main conversation topics include "Practical Guidance," "Information Seeking," and "Writing," which account for nearly 80% of all conversations.
