It would take an ordinary person more than two and a half years to read the entire US Code of Federal Regulations (CFR), which contained more than 104 million words in 2016. 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 Iowa Administrative Code (IAC).
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 IAC are food manufacturing, ambulatory healthcare services, and chemical manufacturing.
State RegData also reveals that the IAC contains 160,306 restrictions and 10.1 million words. It would take an individual 563 hours—or more than 14 weeks—to read the entire IAC. That’s assuming the reader spends 40 hours per week reading and reads at a rate of 300 words per minute. For comparison, there are more than 1.08 million additional restrictions in the federal code. Individuals and businesses in Iowa must navigate these different layers of restrictions to remain in compliance. The IAC organizes regulations by the regulatory agency or department overseeing the rules. Figure 2 shows that the section of the IAC associated with the Public Health Department contains more than 24,000 restrictions. By this measure, this is the biggest regulator in Iowa. Coming in second is the Natural Resources Department, with more than 20,000 restrictions.
Federal regulation tends to attract the most headlines, but it is important to remember that the more than 104 million words and 1.08 million restrictions in the federal code significantly understate the true scope of regulation in the United States. States like Iowa write millions of additional words of regulation and hundreds 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 Iowa regulation in 2017 is a good indicator, then the states are also active regulators, suggesting that the true impact of regulation on society is far greater than that of federal regulation alone.
