"Like a Pittsburgh Wikipedia"
For the advanced cartophiles who want to drill down into neighborhood maps we allow partial access to the general public of our Pittsburgh Neighborhood and Community Information System. Zoom right down to your house for the neat stuff. One of the stories above mentions a survey of residents by neighborhood. For contrast for where we were 30 years ago, I really think the last comprehensive neighborhood level survey done of city residents is this survey from 1980 completed by the late Roger Ahlbrandt whom I have mentioned before. (we'd love to do that survey again btw... unfortunately it's not cheap to have a survey large enough to get reportable results for each neighborhood in the city). He wrote a lot about neighborhoods and community development here in Pittsburgh and if you want to understand how we got from there to here (define 'there' and 'here' as you wish) I would start with some of his writings. Also, my colleagues all just got back from a conference of the National Neighborhood Indicators Partnership at the Urban Institute.
