The demographic relevance of foreign-born population in Barcelona and its inner metropolitan ring is undeniable as key player in the current demographic, residential and urban dynamics. By 2022, the immigrant population in the Barcelonés comarca amounted to 28.5% of the population, or 650.141 people. Consequently, it is interesting to analyze their housing strategies, spatial distribution, and impact on housing markets, especially in areas like Barcelona, where the excessive cost of renting generates a large part of the residentially excluded population. Therefore, nowadays, an important part of the housing supply appears as shared housing, coming from informal residential markets, since there are no specific regulations governing them. Thus, this study examines the distribution of the supply of shared housing in relation to the presence of foreign immigrants, the average rental price and households’ income at the census tracts scale. Due to the absence of official statistics regarding the phenomenon, the study is based on information extracted by web scrapping from Idealista.com, the real state website with the highest online traffic in Spain and volume of listings, collecting data from 13300 of them, at four moments in time. This information is processed by auto spatial correlation index Local Moran’s I that allows to identify cluster areas with similar characteristics. The hypothesis is that the presence of shared housing in certain areas increases the prices of the primary housing rental market, causing the immigrant population to have to pay a higher average price for dwelling when living in a shared house. Early results show that the spatial distribution of the shared housing supply seems to respond to patterns related to the variables studied, clearly visible with clusters. In addition, they also show that there are two opposite trends in areas with a high percentage of low-income households and of immigrant population.
