Housing need

Latin America and the Caribbean has one of the highest urban growth rates in the world. Between 2000 and 2030, the urban population growth is expected to grow 394 million to 609 million people. Additionally, the United Nations predicts that in 2020 the percentage of the population residing in urban zones will outnumber that of developed nations, becoming the most urbanized region in the world with 80 percent of its more than 600 million inhabitants living in cities.

A simple roof versus adequate housing

Between 1990 and 2000, the housing deficit in Latin America rose from 38 to 52 million. According the UN Special Rapporteur on Housing, this is in part explained by the reduction of public investment in low-income housing in certain countries of the region.

Nevertheless, when referring to a housing deficit in Latin America, it is more suffice to say that, while many people have a roof over their head they lack basic elements of adequate housing—such as water and sanitation—that permit them to live in peace and security.

According to statistics published in the XVI General Assembly of Ministries and Maximum Authorities of Latin America and the Caribbean, only 60 percent of the families in the region have access to adequate housing. In addition, 22 percent live in houses that require significant structural improvements and 18 percent are in need of an entire new home. (MINURVI)
