More mapping - the next front in neighbourhood approaches?

Toronto's 140 neighbourhoods have a massive and growing data set being developed for use by anyone free of charge - and provides a visual and accessible way to think about neighbourhoods:

Wellbeing Toronto is a new web-based measurement and visualization tool that helps evaluate community wellbeing across the city's 140 neighbourhoods. Using geographic information software, Wellbeing Toronto allows you to select, combine and weight the significance of a number of indicators that monitor neighbourhood wellness. The results appear instantly on easy to read maps, tables and graphs. This free tool supports decision making and seeks to engage citizens and businesses in understanding the challenges and opportunities of creating and maintaining healthy neighbourhoods. You can also find detailed demographic information about each neighbourhood, prepared by the City's Social Policy Analysis & Research Unit
