NY Bill Would Require Online State Records
NewYorkCountryLawyer writes "Micah Kellner, the New York State assemblyman who last year submitted a bill to provide a tax credit to open source developers, has now proposed the 'Open New York Act,' a law that would make it mandatory for state agencies to put almost all of their public records on the Internet. According to Kellner's office, the law would 'revolutionize the relationship between New Yorkers and their state government, requiring all state agencies to make their records available through a central website — where the data can be used by activists, entrepreneurs, and others to create a host of applications useful in everyday life.' The Open Government Foundation, Citizens Union, and New York Public Interest Research Group all support the bill."
You can already get much of that data pretty easily from the federal government, e.g. your hypothetical racial map for Chicago.
I do think there are probably bad things one can do with demographic data as opposed to good ones, but I'm not sure you can do much by simply hiding the data. De-facto racial segregation in housing exists long after the eradication of de-jure segregation, and even if you hid the data, people who live in a city are going to notice that neighborhoods have different demographics, and if they were going to avoid neighborhoods with races they don't like, they can (and do) already do it without the app.
