AI in Academic Writing 2026: 70+ Global Statistics (UK, US, EU, LATAM)

The transformation of academic writing by artificial intelligence is one of the fastest-moving empirical stories in higher education. What was a fringe behaviour in 2022 is now the majority experience: most university students globally use AI tools as part of their academic writing workflow in 2026. The question facing institutions, researchers, and students is no longer whether AI is present in academic writing — it is what form that presence takes, and what its consequences are for learning, integrity, and the nature of scholarship itself.

This article compiles over 70 verified statistics on AI in academic writing drawn from the Digital Education Council, Turnitin, the Quality Assurance Agency (QAA), Frontiers in Education, Nature, Gallup, and regional education authorities in the UK, US, EU, and LATAM. Sources are cited for every data point. For the predecessor article covering AI statistics in academic writing from the 2023-2024 period, see our AI academic writing statistics roundup.
