It's not just one country lagging behind either. It's believed that 40 percent of the countries monitored won't achieve the education goals until the year 2100.
Wealth is one of the biggest factors for how long each country will likely take. High-income countries like the U.S., Russia and Sweden already achieved universal primary education back in 1970.
The average low-income country is predicted to reach that same mark in 2088.
War and conflict have also been major obstacles in many countries. The terror group Boko Haram has been targeting schools and teachers in Nigeria to keep children from getting a Western-style education.
And while Syria achieved universal primary education in 2001, its civil war has been so destructive that the country isn't expected to reach that mark again until at least 2060.
But many developed countries without armed conflicts within its borders are still expected to miss the 2030 deadline. The U.S. is forecast to be 10 years behind schedule for universal secondary education.
Thousands of lives could be saved with universal education around the world. Reports show higher education is linked to lower infant mortality rates, greater disaster survival rates, increased income and more sustainable farming practices, among other positive impacts.
