Most Regulated States
All states ranked by total number of new state-level regulations across all tracked categories. Rankings use the jurisdictions PlainRegWatch tracks, with data from state legislatures, NCSL, and IAPP; see our methodology.
What This Ranking Tells Us
States with the most regulations tend to be larger, more economically diverse states that serve as regulatory laboratories. California consistently leads due to its large economy, diverse industries, and politically active consumer protection environment. States like Illinois, Colorado, and New York follow as they enact comprehensive frameworks across privacy, employment, AI, and environmental categories. High regulation counts reflect both legislative activity and the breadth of issues a state chooses to address through law rather than market self-regulation.

Frequently Asked Questions
Does more regulation mean overregulation?
Not necessarily. Regulation quantity says nothing about quality or burden. Some states enact many narrowly targeted laws that address specific problems efficiently, while others may have fewer but broader regulations with greater compliance costs. The economic impact depends on implementation, enforcement, and how regulations interact with each other.
Why do some states regulate more than others?
Factors include state population size and economic complexity (larger economies have more issues to address), political culture (some states prefer proactive regulation while others favor market solutions), industry presence (tech-heavy states lead on data privacy), and consumer advocacy strength. Federal preemption also plays a role, states regulate more in areas where federal law is absent.
How often is this data updated?
PlainRegWatch tracks regulations as they are enacted, proposed, or take effect. Data is updated as state legislatures complete their sessions and new laws are signed. Most state legislative sessions run January through June, with updates reflecting the latest enacted legislation.
