Editing Demographics of Ecuador (section)

===Geography===
Due to the prevalence of [[malaria]] and [[yellow fever]] in the coastal region until the end of the 19th century, the Ecuadorian population was most heavily concentrated in the highlands and valleys of the "Sierra" region. Today's population is distributed more evenly between the "Sierra" and the "Costa" (the coastal lowlands) region. Migration towards the cities—particularly larger cities—in all regions has increased the urban population to about 55 percent.

The "Oriente" region, consisting of Amazonian lowlands to the east of the Andes and covering about half the country's land area, remains sparsely populated and contains only about 3% of the country's population, that for the most are indigenous peoples who maintain a wary distance from the recent Mestizo and white settlers. The territories of the "Oriente" are home to as many as nine indigenous groups: [[Quichua]], [[Shuar people|Shuar]], [[Achuar people|Achuar]], [[Huaorani|Waorani]], [[Siona people|Siona]], [[Siona people|Secoya]], [[Shiwiar]], and [[Cofán people|Cofan]], all represented politically by the [[CONFENIAE|Confederation of Indigenous Nationalities of the Ecuadorian Amazon, CONFENIAE]].

As a result of the oil exploration and the development of the infrastructure required for the exploitation of the oil fields in the eastern jungles during the seventies and early eighties, there was a wave of settlement in the region. The Majority of these wave of internal immigration came from the southern province of Loja as a result of a drought that lasted three years and affected the southern provinces of the country. This boom of the petroleum industry has led to a mushrooming of the town of [[Lago Agrio]] ([[Nueva Loja]]) as well as substantial [[deforestation]] and pollution of wetlands and lakes.
