A closer look at per capita homicide rates for each state from FBI Uniform Crime Reports Bureau of Justice Statistics indicate that Louisiana's per capita homicide rate has ranked 1st every single year from 1989 to 2010, which is 22 consecutive years.
Southern states had the highest overall crime rates. Crime can also be isolated to one particular part of a state. Lafayette, Louisiana, for instance had 6 murders per 100,000 people in 2004, while New Orleans, Louisiana, had 56 murders per 100,000 people according to Bureau of Justice Statistics for the same year
Almost all of the nation's wealthiest twenty states, which included northern mid-western and western states such as Minnesota and California, had crime rates below the national average. In addition to having the country's lowest crime rates, New England states also had the country's highest median household income, while the Southern states have the lowest.
This contrasts starkly to some of the nation's poorer states such as Florida or Louisiana. Louisiana had a crime rate 27% and a homicide rate 130.9% above the national average and ranked as the nation's fourth poorest state with a median household income 20% below the national median. While poorer states generally have higher crime rates, several states who fell below the national median for household income such as Maine and Kentucky also had crime rates below the national average, while some wealthier states such as Maryland had crime rates above the national average.
