On this site you can request records from every New York City agency by filing a Freedom of Information Law (FOIL) request. But, some government information is already available online and you wouldn’t need to go through the FOIL process. Check out these links to sites that host government reports and data. You may find what you are looking for without FOIL.
Government Reports and Data are available here
Almost all City agencies also use this platform to respond to FOIL requests and publish records not covered by privacy and other protections.
