The paper presents the urbanization process lived in Chile, and in much
of Latin America, associating the demographic changes to the housing and
urban needs, and the public policies addressing them. The resulting unequal
provision of services and equipment in our cities, among other social
problems, resulted in what was considered an «unexpected» social explosion
in October 2019, followed closely by the sanitary crisis brought by
COVID-19. The paper ends with five propositions regarding the cities of
today in light of both crisis: the social and the sanitary crisis.
