It would take an ordinary person almost three years to read the entire US Code of Federal Regulations (CFR), which contained nearly 104 million words in 2017. 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 large body of federal regulation. A prime example is the online version of the 2019 Administrative Rules of Montana (ARM).
Researchers at the Mercatus Center at George Mason University developed State RegData, a platform for analyzing and quantifying state regulatory text. State RegData captures information in minutes that would take hours, weeks, or even years to obtain by reading and counting. 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. These regulatory restrictions are instances of the words and phrases shall, must, may not, prohibited, and required, and they can signify legal constraints and obligations. As shown in figure 1, the three industries with the highest estimates of industry-relevant restrictions in the 2019 ARM are professional, scientific, and technical services (which includes legal services, accounting and tax preparation, and a variety of other professional services); animal production and aquaculture; and mining (except oil and gas).
State RegData also reveals that the 2019 ARM contains 60,086 restrictions and 4.7 million words. It would take an individual about 263 hours—or nearly 7 weeks—to read the entire ARM. That’s assuming the reader spends 40 hours per week reading and reads at a rate of 300 words per minute. By comparison, there are 1.09 million additional restrictions in the federal code. Individuals and businesses in Montana must navigate these different layers of restrictions to remain in compliance.
The regulations in the ARM are organized by the department that oversees particular rules. Figure 2 shows that the state Department of Public Health and Human Services oversees 11,843 restrictions. By this measure, this is the biggest regulator in Montana. Coming in second is the Department of Labor and Industry, with 9,232 restrictions.
Federal regulation tends to attract the most headlines, but it is important to remember that the nearly 104 million words and 1.09 million restrictions in the federal code significantly understate the true scope of regulation in the United States. States like Montana 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 Montana regulation in 2019 is a good indicator, then the states are also active regulators, suggesting that the full impact of regulation on society is far greater than that of federal regulation alone.
