Sub-Saharan Africa
Education

Forty per cent of African scientists live in OECD countries, predominantly in Europe, the United States and Canada. This has been described as an African brain drain. According to Naledi Pandor, the South African Minister of Science and Technology, even with the drain enrollments in sub-Saharan African universities tripled between 1991 and 2005, expanding at an annual rate of 8.7%, which is one of the highest regional growth rates in the world. In the last 10 to 15 years interest in pursuing university-level degrees abroad has increased.

According to the CIA, low global literacy rates are concentrated in sub-Saharan Africa, West Asia and South Asia. However, literacy rates in sub-Saharan Africa vary significantly between countries. The highest registered literacy rate in the region is in Zimbabwe (90.7%; 2003 est.), while the lowest literacy rate is in South Sudan (27%).

Research on human capital formation was able to determine, that the numeracy levels of sub-Saharan Africa and Africa, in general, were higher than numeracy levels in South Asia. In the 1940s more than 75% of the population of sub-Saharan Africa was numerate. The numeracy of the West African countries, Benin and Ghana, was even higher with more than 80% of the population being numerate. In contrast, numeracy in South Asia was only around 50%.

Higher diversity in Sub-Saharan African countries has been found to lead to a poorer economy. Researchers have argued that this is because of ethnic favoritism in their politics. Sub-Saharan leaders are more likely to provide better resources to their coethnic groups when in power. A study found that, on average, children of the favored ethnic group are 2.25% more likely to attend primary school and 1.80% more likely to complete primary school. A 1% increase in GDP is associated with a 1.5% increase in the ethnic favoritism effect on primary school attendance.

Sub-Saharan African countries spent an average of 0.3% of their GDP on science and technology in 2007. This represents an increase from US$1.8 billion in 2002 to US$2.8 billion in 2007, a 50% increase in spending.
