Immigration Prof Blog reports on a new study from the National Bureau of Economic Research disproving the myth that immigrants have higher crime rates.  The study found that immigrants have much lower incarceration rates than the native border: one-fifth the rate of natives.  Evidence also shows that deportation does not drive the results.  In investigating the reasons, the authors espouse that the process of migration selects individuals who are less likely to commit crimes and are more responsive to response to deterrent effects than the average native-born.
