Education spurs growth and unlocks potential. After all, a single year of primary education creates a 10 to 20 percent increase in a woman's wages later in life. Education lowers the risk of disease and decreases the likelihood that a child will fall into violence and crime. And a child born to a literate mother is 50 percent more likely to survive past age five. No country has achieved sustained growth without at least 40 percent literacy for its adults.
