About

From website:

DataSF is a clearinghouse of datasets available from the City & County of San Francisco. While there is plenty of room for improvement, our goal in releasing this site is:

(1) improve access to data

(2) help our community create innovative apps

(3) understand what datasets you'd like to see

(4) get feedback on the quality of our datasets.
