NYC Open Data offers over 1,100 machine-readable datasets created by city government agencies. By releasing this data, New York City government encourages residents and organizations to participate in and improve government by conducting research and analysis. The data is collected by various government agencies and then analyzed and shared by the Mayor’s Office of Data Analytics (MODA), the Department of Information Technology and Telecommunications, and NYC Digital. The datasets are refreshed when new data becomes available. MODA amalgamates what had been disconnected pieces of information from various city organizations and combines it with other open data from state and federal agencies. NYC Open Data offers datasets on buildings, infrastructure, businesses, permits, crime, licenses, streets, 311 complaints, and more. Researchers, developers, citizens (anyone) can search by category or the creating city agency to find the dataset they are looking for.
