I wonder what is their source for public schools [0] and neighborhoods [1] data. I once tried to get access to same kind of data from ACRIS but the annual bill was around $50k. May be I was doing something wrong or asking for too much. Would be interested in knowing if someone has any insights. 0 - http://www.city-data.com/neighborhood/Battery-Park-City-New-York-NY.html http://www.city-data.com/neighborhood/Battery-Park-City-New-... 1 - http://www.city-data.com/school/edward-r-murrow-high-school-ny.html http://www.city-data.com/school/edward-r-murrow-high-school-...
