The Arizona Center for Investigative Reporting compared the text of every bill introduced during the 52nd Legislature's second regular session to more than 500,000 bills from other states using a machine-learning algorithm designed by data scientists at the University of Chicago. The algorithm assigned scores to phrases in Arizona bills by how closely they match other states' legislation.
Each circle in the chart below represents an Arizona bill and is sized according to its number of matched phrases. Hover over them for details.
