To give New Yorkers the access they deserve to government data and information, Governor Andrew M. Cuomo launched the Open NY initiative in March 2013 and signed Executive Order 95. It directs state agencies to identify, catalog, and publish their data on the state's open data website administered by the Office of Information Technology Services (ITS). Open NY increases transparency, improves government performance, empowers New Yorkers to participate in government, and encourages research and economic opportunities statewide.
