Until the later part of the nineteenth century, many people in the southwest lived in small villages. However, the twentieth century has initiated a progressive urbanization, with approximately 75 percent of the population now living in cities. This change has come from the industrialization of towns and mining areas, the destruction of many rural crafts, and the widespread modernization of agriculture, all leading to the destruction of communal lands and a general exodus to the cities. Villages today tend to consist of densely packed houses surrounded by farmland that is often dispersed. Tourism, ranging from specialized communities to independent homes, has also affected the settlement patterns.
