The Healthy Immigrant Thesis

Alex Nowrasteh, an immigration policy analyst, explains:
Both the Census-data driven studies and macro-level studies find that immigrants are less crime-prone than natives with some small potential exceptions.
There are numerous reasons why immigrant criminality is lower than native criminality. One explanation is that immigrants who commit crimes can be deported and thus are punished more for criminal behavior, making them less likely to break the law.
Another explanation is that immigrants self-select for those willing to work rather than those willing to commit crimes. According to this “healthy immigrant thesis,” motivated and ambitious foreigners are more likely to immigrate and those folks are less likely to be criminals.
This could explain why immigrants are less likely to engage in “anti-social” behaviors than natives despite having lower incomes. It’s also possible that more effective interior immigration enforcement is catching and deporting unlawful immigrants who are more likely to be criminals before they have a chance to be incarcerated.
The above research is a vital and missing component in the debate over the supposed links between immigration and crime.


  1. Perhaps for documented (legal) immigrants. Undocumented immigrants have committed one crime each at minimum.

  2. census data? ha ha ha

    I wonder what are the statistics regarding automobile accidents, no insurance and no economic accountability, plus the illegals breaking of immigration laws.

  3. Ann Coulter debunked these studies in her most recent article, "Every Pro-Immigration Claim Is A Lie"


    I looked up some of these alleged studies this weekend. They're all hidden behind ridiculous Internet paywalls. I was often only the sixth person to read them.

    It turns out that neither Piquero nor Bersani compared immigrant crime to "the overall population" -- as the British Guardian recently claimed in an article purporting to prove Donald Trump wrong. Rather, they compare immigrants' crime rate to the crime rate of America's most criminally inclined subgroups.

    Thus, for example, once you get past the paywall, you will find that Piquero and Bersani's joint study, "Comparing Patterns and Predictors of Immigrant Offending Among a Sample of Adjudicated Youth," used as its base group "adolescents who were found guilty of a serious offense."
