Abstract
In this paper we map the location and distribution of HIV service providers across Toronto neighbourhoods. Our analysis identified an uneven distribution of services across Toronto and a number of communities that are less accessible to HIV-related services. We subsequently identified three neighbourhood-level characteristics of the populations living within these communities (i.e. concentrated economic disadvantage, concentrated immigration, and residential instability). Our findings suggest a significant overlap in the location of HIV service providers and the clustering of neighbourhood-level demographic and socioeconomic factors. Some inaccessible neighbourhoods overlap with clusters of neighbourhoods with higher levels of concentrated disadvantage, immigration and percentage of black Canadians. Accessible neighbourhoods are located within the downtown core of Toronto and overlap with clusters of highly dense, younger neighbourhoods (with a high proportion of 15- to 34-year-olds who are unmarried). Our findings point to the need for policy-makers to integrate spatial analytic techniques into their examination of the types of neighbourhoods, and subsequently the community members that live within those neighbourhoods, that are potentially underserved with respect to health and social services.
