Nigeria
The average Nigerian IQ is 91.35. This is below the global average and is proof of Nigeria's rise in education and technology.
Nigeria is the most populous nation in Africa, with a highly heterogeneous population of over 200 million. This diversity includes significant differences in access to education, healthcare, and nutrition—drivers of regional IQ variation.
The good news is that with a thriving youth population, Nigeria has great potential to see its cognitive development indicators improve in the next few decades.

Factors Influencing IQ Levels in Nigeria
- Cultural Expectations: Children in most Nigerian homes, particularly rural ones, must join domestic or agricultural work early. This tends to reduce brain stimulation or guided playtime, which is key for cognitive development.
- Intellectual Migration: Many of Nigeria's most talented experts emigrate for better pastures, leaving the systems they exit short of yet more mentors, innovators, or thinkers—limiting intellectual exposure for subsequent generations.
- Environmental Toxins: In some parts of the Niger Delta, oil pollution and tainted drinking water have raised alarms about neurotoxic effects on children's growth.
- Religious and Traditional Influences: While highly cultured, some conservative communities may limit exposure to different ideas or thinking paradigms—especially for girls.
- Technology Access Divide: While Nigeria is rapidly becoming digitized, the rural-urban technology divide means that most children still lack exposure to the Internet, e-learning platforms, or online problem-solving environments that support IQ growth.
How Nigeria’s IQ Compares to Other Countries
Nigeria's average IQ is the same as most developing nations, especially in Sub-Saharan Africa, like Ghana (90.25).
It is lower than that of African countries like South Africa (94.11) but comparable to those with similar development problems.
Benin (86.88), Togo (89.94), and Cameroon (89.94) are three countries close to Nigeria and they all have lower scores, showing how education and health system affect this number.
Importantly, Nigeria's huge population and emerging middle class also mean that aggregate IQ figures do not always capture the impressive progress made in education, technology, and innovation by certain social groups.
