Homeless Shelter Flows in Calgary and the Potential Impact of COVID-19

Abstract

Social distancing and self-isolation are two of the key responses asked of citizens during a pandemic. For people without a home, this advice is rather more difficult to follow. In this article, we use daily data describing the movements of 36,855 unique individuals who used emergency homeless shelters in Calgary over the period 1 January 2014–31 December 2019. We show that the use of emergency shelters is characterized by large flows from and into the broader community and smaller flows between individual shelters. Between admissions of new people into the shelter system and multiple re-admissions of current clients, there were an average of 43,613 movements between the community and between shelters each month. The size of these flows provide a measure of the extent to which people reliant on homeless shelters are exposed to the risk of transmission of coronavirus disease 2019 (COVID-19). By identifying the size and nature of these flows, we hope our analysis helps identify responses that may minimize this population’s risk of exposure.
