The aim of this paper is to study the differences in homeownership of international migrants in Buenos Aires, from a demographic perspective still little applied to the subject in Latin America, which explores the intensity and calendar of the phenomenon in specific generations, groups and territories. Birth cohorts of different national groups were reconstructed based on variables such as age and place of birth from the Argentine population censuses from 1970 to 2010. As a main result, it was found that the older the population, the more widespread is homeownership, but access to land has become more restrictive. This has affected recent generations in general, including the Argentine population, but especially migrants from neighboring countries of lower social sectors and in the most disputed territories of the city.
