Digital education spans internet access, connected schools, online platforms, digital devices, teacher preparation, ICT skills and education-management systems. The statistics below distinguish global estimates, OECD surveys, country examples and COVID-era emergency measures so that access, adoption and outcomes are not treated as interchangeable.
Key Digital Education Statistics
The most useful headline measures cover both opportunity and limitation:
- In the latest available household survey data reported in 2020, only 33% of children and young people aged 25 or less had internet access at home globally.
- In the same 2020 global estimate, 2.2 billion children and young people aged 25 or less did not have internet access at home.
- In 2020, home internet access was 5% among children and young people in West and Central Africa.
- In 2020, home internet access was 87% among children and young people in high-income countries.
- At the height of nationwide COVID-19 lockdowns, up to 1.6 billion children were affected by school closures globally.
- During COVID-19 school closures, 91% of countries used online learning platforms to deliver distance learning globally.
- During the same period, online learning platforms reached about 25% of students globally.
- During COVID-19 school closures, at least 500 million students, or 31% worldwide, could not be reached by remote learning.
- During the COVID-19 disruption, 89% of learners in sub-Saharan Africa lacked access to a household computer.
- In 2022, at least half of the world’s lower-secondary schools were connected to the internet for pedagogical purposes.
- In PISA 2022, 78% of students in OECD countries were in schools with an effective online learning-support platform.
- In PISA 2022, 88% of OECD students were in schools whose principals reported that teachers had the skills to integrate digital devices.
- In PISA 2022, 7.8% of OECD students spent 5–7 hours per day on digital devices for learning activities in school.
- In 2022, 45% of OECD students felt nervous or anxious when their digital devices were not nearby.
- In 2018, 74% of upper-secondary VET teachers in six OECD countries or regions used digital technology with students.
- In 2022–24, 24% of adults in the median reporting country verified information found online.
- In 2023, only 54% of countries globally had unique student-identification mechanisms.

Digital Education Access and the Global Connectivity Gap
The ITU-UNICEF household-survey estimates show why digital education access cannot be inferred from the existence of online content. In the latest available data reported in 2020, only 33% of children and young people aged 25 or less had internet access at home globally, leaving an estimated 2.2 billion without home access; this age group includes people up to 25 and is not limited to enrolled students (ITU, “How many children and young people have internet access at home?”).
| Population or location | Home internet access | Period and definition |
|---|---|---|
| Global, age 25 or less | 33% | Latest available household surveys reported 2020 |
| West and Central Africa, age 25 or less | 5% | Latest available household surveys reported 2020 |
| Low-income countries, age 25 or less | 6% | Available household surveys reported 2020 |
| High-income countries, age 25 or less | 87% | Available household surveys reported 2020 |
These are household-access estimates, not measures of individual use or participation in online courses. The same source reported that one in five school-age children aged 3–17 were out of school before COVID-19 closures, while an estimated 617 million children and adolescents were not reaching minimum proficiency in reading and mathematics; neither measure is a direct indicator of digital access (ITU).
The 2023 UNESCO Global Education Monitoring report adds a school-level measure: at least half of the world’s lower-secondary schools were connected to the internet for pedagogical purposes in 2022. Coverage and definitions vary by country, and school connectivity does not guarantee a device or connection at home (UNESCO, “Technology in education – 2023 GEM Report”).
Remote Learning Reach During School Closures
Emergency remote learning expanded policy activity quickly, but policy adoption and student reach were different measures. During the COVID-19 school-closure period, more than 90% of education ministries adopted some type of remote-learning policy, including radio, television and internet channels, while 91% of countries used online learning platforms (ITU; UNESCO).
- Up to 1.6 billion children were affected by school closures at the peak of nationwide lockdowns globally.
- Online learning platforms reached about 25% of students globally during school closures.
- At least 500 million students, or 31% worldwide, could not be reached by remote learning.
- Among students not reached, 72% were among the poorest and 70% lived in rural areas.
These figures estimate access or reach, not learning achievement. In sub-Saharan Africa, 89% of learners lacked access to a household computer and 82% lacked internet access at home during the disruption; mobile or community access is not included in the home-internet figure (UNESCO).
Country programmes illustrate how channels differed. In Nigeria, radio instruction combined with print and audiovisual materials reached nearly 80% of nomadic learners in a programme reported as operating since the 1990s, while Ukraine’s pandemic digital platform allowed 85% of schools to complete the academic year in 2022; neither figure is a national online-learning adoption rate (UNESCO).
Digital Education Adoption in Schools and Classrooms
PISA 2022 provides a more stable school-readiness picture for OECD countries, based largely on principal reports. The reported availability of digital infrastructure and teacher capacity rose between 2018 and 2022, but these figures describe reported conditions rather than actual frequency or quality of classroom use (OECD, “Investments in a solid foundation for learning and well-being”).
| PISA 2022 measure | OECD student share | Change from 2018 |
|---|---|---|
| Effective online learning-support platform | 78% | +26 percentage points |
| Teachers with technical and pedagogical digital-integration skills | 88% | +24 percentage points |
| Effective professional resources for teacher digital-device learning | 76% | +13 percentage points |
The computer-to-student ratio averaged 1.0 in rural schools and 0.8 in urban schools across OECD countries in 2022. Rural schools had a higher ratio than urban schools in 24 participating countries or economies, but the ratio does not show device quality, use outside school or whether students shared equipment (OECD).
Formal subject-specific guidelines for digital-device use were positively related to preparedness for digital learning in 34 PISA-participating countries and economies. This is an adjusted association, not evidence that guidelines caused preparedness (OECD).
Teacher Digital Skills and Online-Learning Preparation
School capacity depends on time, support and incentives as well as hardware. In PISA 2022, 59% of OECD students attended schools whose principals reported sufficient teacher time to prepare lessons integrating digital devices, and the same share attended schools with sufficient qualified technical-assistance staff; 55% attended schools where teachers were offered incentives to integrate digital devices (OECD).
In a broader global policy review reported by UNESCO in 2023, only 20% of education systems required schools to offer computer science as an elective or core course. A curriculum requirement measures policy, not enrollment or teaching quality (UNESCO).
The OECD’s TALIS-based comparison also shows differences by education track. In six OECD countries or regions with available 2018 data, 74% of upper-secondary VET teachers used digital technology with students, compared with 66% of general-education teachers; 46% of upper-secondary VET teachers reported ICT skills as their greatest training need (OECD, “Shaping Digital Education”).
The same OECD source reports that 46% of educators in the United States had taught an online course before the pandemic, based on a pre-2020 survey and cited secondary research. Across the OECD in 2018, 22% of TALIS teachers reported a high need for further training on teaching students with special educational needs; this is not specific to digital assistive technology (OECD).
Digital Learning Outcomes, Device Use and Student Wellbeing
PISA 2022 links learning-device time with mathematics performance, but the results are observational. Students who spent 5–7 hours per day on digital devices for learning activities in school scored 12 points lower in mathematics than students spending 3–5 hours; after socioeconomic adjustment, the gap was 10 points, and students spending more than 7 hours scored lower still (OECD).
Only 7.8% of OECD students reported spending 5–7 hours per day on these in-school learning activities in 2022. The measure is student-reported device time and does not establish that additional device use caused lower scores (OECD).
Wellbeing measures also matter. In 2022, 45% of OECD students reported feeling nervous or anxious when their digital devices were not nearby, and that feeling was negatively correlated with mathematics performance in 45 countries and economies; the reported association was adjusted for socioeconomic profile and is not causal (OECD).
A specific Chinese lesson-recording intervention was reported to improve outcomes for 100 million rural students by 32% and reduce urban-rural earning gaps by 38%. These are programme estimates from the report summary; the outcome definition and underlying study design should be checked, and earnings effects are not the same as short-term learning gains (UNESCO).
Digital Skills, Online Platforms and Education-System Capacity
Adult ICT-skills data provide context for the population that supports digital learning, but the latest UNESCO monitoring figures are not globally representative. In 2022–24, 85% of reporting countries were upper-middle- or high-income, so the following are median reporting-country results rather than global averages (UNESCO, “Monitoring education in the SDGs”).
| Adult capability in the median reporting country | Share | Period |
|---|---|---|
| Participated in social networks | 68% | 2022–24 |
| Could copy and move files | 54% | 2022–24 |
| Could prepare electronic presentations | 33% | 2022–24 |
| Verified information found online | 24% | 2022–24 |
| Had programming skills | 6% | 2022–24 |
Education-management systems determine whether platforms can identify learners and support continuity. Only 54% of countries globally had unique student-identification mechanisms in a 2023 report, compared with 22% in sub-Saharan Africa; this is a system-capacity indicator, not a measure of individual access (UNESCO).
Policy attention to data also expanded, although policy references do not establish implementation. Since the 1990s, references to data, statistics and information increased 13-fold in high-income countries, ninefold in upper-middle-income countries and fivefold in low- and lower-middle-income countries (UNESCO).
Digital education capacity includes safety and privacy. A systematic review covering interventions in Australia, Italy, Spain and the United States estimated a 76% average chance that cyberbullying-prevention programmes reduced perpetration; in Brazil, 29% of schools had conducted debates or lectures on privacy and data protection, while New Zealand’s digital protection programme served almost 2,500 state and state-integrated schools (UNESCO).
These are intervention or programme measures, not general estimates of student mastery or learning impact.
