Average IQ (contested)

Estimated national average IQ.

These national IQ estimates are widely criticised: many rely on tiny, unrepresentative samples, are decades old, or are imputed from neighbours, and scores track schooling, nutrition and health far more than anything innate. Treat them as a curiosity; “Learning outcomes” is the more robust measure.
