Reg Stats
The charts on this page have been featured in a number of publications. Please contact us if you would like to use these files in your publication or presentation.
The effects of regulation—both benefits and costs—are difficult to measure, particularly when considered in the aggregate. As a result, analysts often turn to indirect proxies to understand the reach and impact of regulations over time.
The information here provides accessible charts and supporting data to better understand disparities and similarities across presidential administrations, and their cumulative approaches to implementing regulatory policy. Our team of policy analysts update these charts on a regular basis as new data are available.

Economically Significant Final Rules Published by Presidential Year
This graph presents the number of economically significant final rules published each presidential year. Economically significant rules are regulations issued by executive branch agencies that meet this definition in Executive Order 12866: “Have an annual effect on the economy of $100 million or more or adversely affect in a material way the economy, a sector of the economy, productivity, competition, jobs, the environment, public health or safety, or State, local, or tribal governments or communities.”
We present numbers by “presidential year” (February 1 through January 31) to understand priorities and activities during presidential terms.

Cumulative Economically Significant Final Rules by Administration
This graph tracks the cumulative number of economically significant final regulations published by executive branch agencies under different administrations, during equivalent months in office, from President Reagan to President Trump.
It is interesting to note how each administration follows the same general trend upward as their time in office elapses, and that each administration (excluding Reagan) has a notable uptick in their final months.

Total Pages in the Code of Federal Regulations and the Federal Register
Total Pages Published in the Code of Federal Regulations
The Code of Federal Regulations (CFR) is the codification of the general and permanent rules promulgated by the departments and agencies of the federal government. The number of total pages published in the CFR annually provides a sense of the volume of existing regulations with which American businesses, workers, consumers, and other regulated entities must comply.
Total Pages Published in the Federal Register
The number of pages in the Federal Register—the daily journal of the federal government in which all newly proposed rules are published along with final rules, executive orders, and other agency notices—provides a sense of the flow of new or changed regulations issued during a given period. These regulations might increase or decrease regulatory burdens, making this an imperfect—but frequently cited—measure of regulatory burden.
