While it is not a surprise that developing countries have low education rates, the true eye opener is the difference in education level between the rich and the poor.
According to the International Monetary Fund - "Equally disheartening are the disparities in educational attainment between different groups within countries and regions. Sadly, but not surprisingly, in most low-income countries, children from poor families are much less likely to be in school than children from more affluent families, except in countries like Uzbekistan that have a strong legacy of universal education. In Pakistan, in the early 1990s, 86 percent of rich children aged 6-14 were in school, compared with 37 percent of poor children, making for a rich-poor gap of 49 percentage points; the gap was 52 percentage points in Senegal, and 63 percentage points in Morocco. The gap is narrower but still wide in countries like Bangladesh, Ghana, and Indonesia."
