Ever wondered which are the most linguistically diverse countries in the world? Well, look no further.

Ethnologue’s language diversity chart (pictured, via The Economist) shows that Papua New Guinea and Congo are the most diverse. Papua New Guinea has an incredible 830 indigenous languages! The chart is based on the number of languages spoken in a country and Greenberg’s diversity index, which “scores countries on the probability that two citizens will share a mother tongue”. That explains why Congo is second on the list despite having a mere 215 indigenous languages compared to third-place India’s 438.

At the bottom of the scale is North Korea, with one indigenous language spoken and a score of nil on the diversity index.
