Cochabamba is a city and municipality in central Bolivia in a valley in the Andes mountain range. It is the capital of the Cochabamba Department and the fourth largest city in Bolivia, with a population of 630,587 according to the 2012 Bolivian census. Its name is from a compound of the Quechua words qucha "lake" and pampa, "open plain." Residents of the city and the surrounding areas are commonly referred to as cochalas or, more formally, cochabambinos.
It is known as the "City of Eternal Spring" or "The Garden City" because of its spring-like temperatures all year round. It is also known as "La Llajta," which means "town" in Quechua.
