There are approximately 448 of these subdivisions in Chihuahua, which house 78% of the population of Chihuahua according to the Instituto de Vivienda del Estado de Chihuahua (IVI, 2011). The monofunctional nature of these housing developments and their location in outlying areas has not lent itself to a transit-supportive environment. It is estimated that in the first semester of 2010, 19.2% of the homes in the State of Chihuahua were not lived in or completely abandoned (Table 4.1). Rates in the major cities were even higher in Ciudad Juarez (23.8%) (IVI, 2011). There is not a parallel for such a market in OECD metro-regions. Ironically, the meteoric rise of the housing stock in Ciudad Juarez from 2000 to 2007 was also associated with the abandonment of several houses throughout the metropolitan region.
