Researchers at the Centre for Research on Inner City Health (CRICH) at St. Michael's Hospital in collaboration with Public Health Ontario are currently preparing a 2011 update of the Ontario Marginalization Index (ON-Marg).  ON-Marg is an area-based measure that can be used to better plan programs and understand how area-based marginalization drives health inequities at the neighbourhood level in urban and rural Ontario. The 2006 version has been widely used in public health and in research, however, over time, these neighbourhoods have changed, and the index needs updating.  The ON-Marg previously only used census data to illustrate levels of marginalization across the province in 2001 and 2006. In 2011, the mandatory long-form census was replaced with the National Household Survey (NHS) which due to its voluntary nature, is less appropriate for studying marginalized populations.  Current update efforts focus on using alternative data sources including Municipal Property Assessment Corporation (MPAC), Statistics Canada Taxfiler, and Immigration, Refugees and Citizenship Canada data.  This presentation will focus on the development status of the 2011 update, including timelines and plans for validation.
