which country has the lowest iq in the world

Studies that rank “which country has the lowest IQ in the world” usually name Nepal as having the lowest reported average IQ, often around the low‑40s on their scaled metrics, with countries like Liberia, Sierra Leone, and Guatemala also appearing near the bottom of such lists. These rankings are highly debated, rely on incomplete and non‑standardized data, and say far more about structural problems like poverty, nutrition, education, and conflict than about the actual intelligence or potential of people in those countries.

Quick Scoop

• Some recent online datasets and articles rank Nepal as the country with the lowest average IQ, followed by several low‑income countries in Africa and Central America.

• These numbers are not official UN or WHO statistics; they come from private tests, modeled estimates, and small or biased samples.

• Experts warn that country‑IQ rankings can be misleading, stigmatizing, and easily misused for racist or discriminatory narratives.

Where “lowest IQ” numbers come from

• Many viral lists draw on compilations like World Population Review–style tables or proprietary online IQ‑test platforms that aggregate voluntary test results by country.

• These sources differ in methodology, sample size, and test type; some use non‑verbal pattern tests, others mix different studies, and many have very limited data for poorer or conflict‑affected states.

Because of this, there is no single universally accepted official answer to “which country has the lowest IQ,” only rough and controversial estimates.

Why those rankings are so problematic

• IQ is strongly shaped by environment: early‑life nutrition, exposure to toxins, years and quality of schooling, childhood illness, war, and displacement all push scores down, sometimes dramatically.

• Countries that appear at the bottom of IQ tables tend to face severe challenges such as chronic poverty, food insecurity, weak school systems, and ongoing or recent conflict, which limit children’s opportunities to develop cognitive skills measured by these tests.

So a “low national IQ” is better understood as a signal of inequality and deprivation , not of any inherent lack of intelligence in a population.

How to read (and not misuse) this topic

• National IQ rankings should never be used to judge the worth, dignity, or potential of people from any country; they reflect harsh social conditions, not fixed ability.

• Researchers increasingly emphasize that intelligence is multi‑dimensional, culturally shaped, and impossible to capture fully with a single number like an IQ score.

The more useful question than “which country has the lowest IQ in the world” is “which countries are being held back the most by poverty, poor health, and lack of education—and what can be done to fix that?”
