Cover Story: The spatial fragmentation in the housing market and the growth of squatter settlements are characteristic for metropolitan areas in developing countries. This study examines the relationship between squatter settlement growth and spatial fragmentation in the housing market of Buenos Aires. GWR analysis of the house prices for the years 2001, 2010, and 2018 shows that while squatter settlements had a strongly negative effect on house prices, the affected areas shifted over time. Our findings indicate that it is not the growth of the squatter settlement that causes spatial fragmentation. However, squatter settlements did determine the spatial demarcation of the fragmentation by attracting low-income households to surrounding low house price areas. View this paper
