Imagine adding 327 million students to the world's schools.
That's roughly what has happened since 2000.
According to UNESCO's 2026 Global Education Monitoring Report, primary and secondary enrollment reached approximately 1.4 billion students in 2024.
Compared with 2000, enrollment increased by 327 million students, or 30%.
The scale is easy to overlook because there was no single moment when it happened.
Schools opened. More girls entered classrooms. Governments expanded access. Transportation, electricity, health programs and technology helped previously excluded communities connect with education systems.
Year after year, those changes accumulated.
The result is that hundreds of millions more young people are now in school than at the beginning of this century.
But this is also a good example of why TGITW shouldn't stop at the encouraging number.
The first fifteen years of the century produced substantial reductions in the share of children outside school.
Since 2015, that momentum has slowed.
UNESCO estimates that 273 million children and young people remained out of school in 2024, and the total out-of-school population has now increased for seven consecutive years.
That doesn't erase the enormous expansion that came before it.
It tells us that progress is neither automatic nor irreversible.
The world proved that education access can expand on an extraordinary scale. The challenge now is restarting that momentum.
