About 68% of the world’s languages sampled in an interactive available from the World Atlas of Language Structures don’t have a gender specific pronouns. 254 of the 378 mapped languages in the interactive map don’t use “he” or “she” but instead used a gender neutral pronoun when referring to persons.
Only about 30% of the sample languages used gender specific pronouns. The greatest concentration of languages with gender in personal pronouns is found in Africa. According to linguist Siewierska (1955 – 2011), the other major geographic area where gender in personal pronouns is common is Eurasia and especially Europe.
