Crime rates are decreasing across large cities in the United States, but murder rates are on the rise.

Numerous sources, from city police departments to the Brennan Center for Justice, reported a drastic jump in murder rates in large cities across America from 2014 to 2015. Experts have not yet reached a consensus explanation for this increase, but many have ideas.

Some popular theories include the rise of income inequality, loose gun control and more cautious cops in the wake of events such as the Ferguson shooting.

The decrease in crime and increase in murders, though seemingly counterintuitive, is a trend that has been seen before. For example, in a 1999 paper, Stephen D. Levitt (author of Freakonomics) examined Chicago and its 77 neighborhoods between 1970-1990 as a case study.

In the 1970s, there was a negative correlation between neighborhood income and homicide rates — the higher the income, the lower the rate. The same pattern applied for property crime rates. However, for the next two decades, as income inequality between neighborhoods increased, this negative correlation dwindled. By 1990, the homicide rates in higher-income and lower-income neighborhoods were much more similar. At the same time, though, property crimes significantly decreased for the wealthy.

Regarding the increase in murders from 2014 to 2015 in major U.S. cities, most experts agree that it will be years before the reasons are clear — if reasons exist at all. The increase could end up being an anomalous year-to-year spike.

Whatever the cause, analysts at FindTheHome wanted to find places in America with the highest murder rates. Using the most recent 2014 estimates from the American Community Survey and murder incidence data from the Uniform Crime Report collected by the FBI, they determined the top 30 counties with the highest murder rate per 100,000 people in each state.
