Just drawing back slightly, I note the always stellar work of Max Roser and his “Our world in data” team. A recent series by Esteban Ortiz-Ospina reminds us of key progress in global education outcomes in the last fifty years or so. Consider, that in the last two decades the number of out-of-school children almost halved globally.
He also notes;
- the correlation between learning outcomes and GDP per capita over time.
Each line in this plot tracks one country. As we can see most lines point north-east – this means GDP and learning outcomes often move together.
The evolution of learning outcomes over time
This scatter plot compares outcomes in 1985 and 2015 (or the closest years with available data).
Among these countries we see a broad positive trend: Most bubbles are above the diagonal line, which means the majority of countries have seen improvements in learning outcomes over the last couple of decades. This is a great accomplishment! It shows that policies matter and learning outcomes can, and often do improve.
