The development of a DEA/BOD index about housing vulnerability in brazil

Abstract

This research aims to investigate housing vulnerability in Brazil, through the following variables: deaths and hospitalizations due to waterborne diseases and housing deficit. The aim of this research is to analyze their contributions to housing vulnerability in Brazil. For this, a composite index was created, using the aforementioned variables, such an index was constructed through Data Envelopment Analysis (DEA), using the Benefit of Doubt model. Twenty-seven units were studied, these being the 26 states of Brazil and the Federal District, plus another 9 metropolitan regions, totaling 36. The housing vulnerability index helps to estimate relationships between certain characteristics of each region and its degree of housing vulnerability. For example, the relationship between the high numbers of precarious housing units and the degree of housing vulnerability in the unity. That question is pointed out in the discussion of this work. In addition, the index concludes that the most vulnerable regions of the country are: Maranhão; Acre and Bahia, and that the least vulnerable units are: Rio de Janeiro; Paraná and Tocantins. Regarding metropolitan regions, the most vulnerable units are: Belém and Porto Alegre and the least vulnerable: Curitiba and Rio de Janeiro.
