This recent Pew Charitable Trusts data visualization shows an interesting contrast: Crime is down 40 percent, while imprisonment in federal prisons has risen 24 percent over the last 18 years in the United States. As you’ll see, some states, such as New York, New Jersey and Maryland, have shown a decrease in both units. Meanwhile, West Virginia is the only state that saw an increase in crime and a giant increase in imprisonment. Then there’s Idaho with a 46 percent decrease in the crime rate but imprisonment still rose a whopping 103 percent.
Fun with data? It’s worth noting that most likely not every crime is, or can be, prosecuted.
