We present an innovative approach developed to discern the spatial dimensions of risk for homelessness amongst recent immigrants in Vancouver, Canada. Dasymetric mapping and a postal survey are employed to improve the resolution and utility of census data. The results illustrate the potential for developing a more nuanced understanding of the spatial dimensions of complex socioeconomic phenomena using a combination of secondary data and primary data. It is argued that higher-resolution data aids in identifying and understanding socioeconomic phenomena that are highly localized and misrepresented by coarsely aggregated data. Finally, the potential for population surveillance is discussed and weighed against the benefits for policy-makers, non-governmental organizations, and researchers.

Hospitals are frequently the chosen site of cost containment and rationalization especially in rural areas. Socio-demographic and geographic characteristics make hospital service allocation more difficult in rural and remote regions. This research presents a methodology to model rational catchments or service areas around rural hospitals--based on travel time. This research employs a vector-based GIS network analysis to model catchments that better represent access to hospital-based healthcare services in British Columbia's rural and remote areas. The tool permits modelling of alternate scenarios in which access to different baskets of services (e.g. rural maternity care or ICU) are assessed. In addition, estimates of the percentage of population that is served--or not served--within specified travel times are calculated. The modelling t...
