The Brant Health Atlas is an interactive mapping tool that provides information on the health of residents in the City of Brantford and the County of Brant in Ontario, Canada. Information is available on socio-demographic characteristics and a variety of key health indicators by age, sex and neighbourhood. These health indicators are aligned with core indicators developed by the Association of Public Health Epidemiologists in Ontario (APHEO). The tool allows users to view this information on a map, in tables, or graphs. We spoke to Adam Stevens, epidemiologist at the Brant County Health Unit (www.bchu.org), about the mapping tool and the benefits they have seen from using InstantAtlas.
