It would take an ordinary person more than three years to read the entire US Code of Federal Regulations (CFR), which currently contains more than 112 million words. The sheer size of the CFR poses a problem not just for the individuals and businesses that want to stay in compliance with the law, but also for anyone interested in understanding the consequences of this massive system of rules. States also have sizable regulatory codes, which add an additional layer to the enormous body of federal regulation. A prime example is the online version of the 2017 Minnesota Administrative Rules (MAR).
A tool known as State RegData—a platform for analyzing and quantifying state regulatory text—was developed by researchers at the Mercatus Center at George Mason University. State RegData captures information in minutes that would take an ordinary person hours, weeks, or even years to obtain. For example, the tool allows researchers to identify the industries that state regulation targets most by connecting text relevant to those industries with restrictive word counts. Known as regulatory restrictions, the words and phrases shall, must, may not, prohibited, and required can signify legal constraints and obligations. As shown in figure 1, the three industries with the highest estimates of industry-relevant restrictions in the 2017 MAR are chemical manufacturing, food manufacturing, and animal production and aquaculture.
State RegData also reveals that the MAR contains 98,321 restrictions and more than 5.7 million words. It would take an individual roughly 317 hours—or about 8 weeks—to read the entire MAR. That’s assuming the reader spends 40 hours per week reading and reads at a rate of 300 words per minute. For comparison, in 2017 there were more than 1.15 million additional restrictions in the federal code. Individuals and businesses in Minnesota must navigate these different layers of restrictions to remain in compliance.
The MAR organizes regulations based on the regulatory agency, commission, or department that relates to those rules. Figure 2 shows that the section of the MAR associated with the Minnesota Pollution Control Agency contains more than 15,000 restrictions. By this measure, this is the biggest regulator in Minnesota. Coming in second is the Minnesota Health Department, with more than 14,000 restrictions.
Federal regulation tends to attract the most headlines, but it is important to remember that the more than 112 million words and 1.15 million restrictions in the federal code significantly understate the true scope of regulation in the United States. States like Minnesota write millions of additional words of regulation and tens of thousands of additional restrictions. State-level requirements carry the force of law to restrict individuals and businesses just as federal ones do.
Researchers are only beginning to understand the consequences of the massive and growing federal regulatory system on economic growth and well-being in the United States. Meanwhile, the effects of state regulation remain largely unknown. If this snapshot of Minnesota regulation in 2017 is a good indicator, then the states are also active regulators, suggesting the true impact of regulation on society is far greater than that of federal regulation alone.
