Online Learning Statistics 2026
This page collects 51 figures on online learning: how many college students study at a distance, how many adults take courses at all and how much of that happens online, how large the main course platforms and MOOCs have become, and how many people use language apps. It covers the United States, the European Union, OECD countries, the UK, Canada, Australia and India. Sources are the National Center for Education Statistics, NC-SARA, Eurostat, the OECD, the Learning and Work Institute, the UK Department for Education, Statistics Canada, the Australian Bureau of Statistics, India's Press Information Bureau, and company filings from Coursera, Udemy and Duolingo. Most figures describe 2024 to 2026, and each one is labeled with the year it describes.

Short answer
More than half of U.S. college students, 54.1%, took at least one online course in fall 2023 and 26.1% studied only online, according to NCES. In the EU, 34.8% of internet users took an online course or used online learning material in 2025 (Eurostat), and the OECD finds two in five adults take part in some learning each year. On the platforms, Coursera and Udemy report more than 310 million learners combined, and Duolingo averaged 64.9 million daily active users in Q3 2026, up 29%.

Reading the numbers
Online study is now ordinary in U.S. higher education. NCES counts 10.3 million students, 54.1% of everyone at degree-granting institutions, taking at least one distance course in fall 2023, and almost 5 million studying only at a distance. That compares with 36% of undergraduates taking any distance course in fall 2019. NC-SARA's institution reports show fully online enrollment still growing, up 5.0% to 4.44 million in fall 2024, though well below the 5.8 million peak of fall 2020.
Outside college, online learning keeps spreading but overall participation in adult learning has not grown much. Eurostat found 34.8% of EU internet users doing online learning in 2025, up from 21.4% in 2019, yet Eurostat, the OECD and national surveys all put adult learning participation roughly where it was a decade ago. The Learning and Work Institute's 2026 UK survey found 43% of adults learning in the last three years, barely above 40% in 1996, and Australia's ABS reports a fall from 39% to 34% between 2020-21 and 2024-25.
What has changed is how adults learn. The OECD reports 34% of non-formal training is fully online and in the United States, Canada and England more than 60% happens at a distance. In the UK, 48% of adult learners now study entirely online and nearly half learn for leisure. AI is the fastest-moving subject: Udemy saw AI enrollments grow 120% in 2025, and Coursera reports more than 40 generative AI enrollments a minute in 2026.
Platform numbers are large but need care. Coursera's 205 million registered learners and SWAYAM's 58 million enrollments are cumulative sign-ups, while paying users are far fewer: about 1.6 million paid subscribers across Coursera and Udemy. Duolingo's daily users, 64.9 million in Q3 2026, are a measure of active use and grew faster than its 13.1 million paid subscribers.

Questions readers ask
- How many students take online classes in the U.S.?
- NCES counts 10.3 million students at degree-granting institutions, 54.1% of the total, taking at least one distance education course in fall 2023. About 5 million, or 26.1%, studied exclusively at a distance.
- Is online learning growing?
- Yes, in most measures. Eurostat found 34.8% of EU internet users doing online learning in 2025, up from 21.4% in 2019, and NC-SARA reports fully online college enrollment up 5.0% in fall 2024. Overall adult learning participation is flat or falling in the UK and Australia, though more of it now happens online.
- How many people use Coursera?
- Coursera reported 205 million cumulative registered learners in March 2026. After merging with Udemy, the combined company reports more than 310 million learners and about 1.6 million paid subscribers in Q3 2026.

- Duolingo averaged 64.9 million daily active users and 153.1 million monthly active users in Q3 2026, according to its shareholder letter. It had 13.1 million paid subscribers at the end of September 2026.
- What share of adults take part in learning?
- The OECD's 2023 Survey of Adult Skills finds two in five adults learn each year on average, from 58% in Norway to 13% in Korea, with the United States at 55%. Eurostat's Adult Education Survey put the EU at 46.6% in 2022.
Where these numbers come from
We chose figures that measure online learning and adult learning directly: distance education enrollment in U.S. colleges, online course use in the EU, adult participation in education and training, the delivery mode of adult training, and user counts from the largest course and language platforms. Government and intergovernmental figures come from NCES, Eurostat, the OECD, the UK Department for Education, Statistics Canada, the Australian Bureau of Statistics and India's Press Information Bureau; survey figures for the UK come from the Learning and Work Institute; NC-SARA data come from reports by participating institutions. Platform figures come from Coursera, Udemy and Duolingo filings and their own published reports. Definitions differ widely: some surveys ask about the last four weeks, others about 12 months or three years, and platform 'registered learners' are cumulative sign-ups rather than active users, so the figures should not be added or compared directly. NCES table figures are the latest final data published for fall 2023. We did not use market research roundups or statistics aggregators. Every quote was checked against the source page on the date shown. We store the sentence each number appears in, and a script loads the publisher's page again to make sure that sentence is still there. Our methodology has the details.
