Paraguay's population is distributed unevenly throughout the country. The vast majority of the people live in the eastern region, most within 160 kilometers (100 mi.) of Asuncion, the capital and largest city. The Chaco, which accounts for about 60% of the territory, is home to less than 2% of the population. Ethnically, culturally, and socially, Paraguay has one of the most homogeneous populations in South America. About 95% of the people are of mixed Spanish and Guarani Indian descent. Little trace is left of the original Guarani culture except the language, which is understood by 90% of the population. About 75% of all Paraguayans speak Spanish. Guarani and Spanish are official languages. Germans, Japanese, Koreans, ethnic Chinese, Arabs, Brazilians, and Argentines are among those who have settled in Paraguay.
