RegData U.S. Regulation Tracker:

The RegData U.S. Regulation Tracker allows researchers and other interested parties to visually assess the quantity of regulation in the Code of Federal Regulations (CFR) on a daily basis. The tracker updates daily using the eCFR as its main source for regulatory text. In addition, this tracker allows users to interact with other variables that the QuantGov data supplies, such as the levels of regulation targeting specific industries or the quantities produced by regulatory agencies at different points in time.
