Using the data collected by the National Epidemiologic Survey on Alcohol and Related Conditions interviews, researchers uncovered the Immigrant Paradox — immigrants are less antisocial than native-born Americans:
The most intriguing aspect of this study, however, barely made the press reports, T. Greer notes — America makes you violent:
In these analyses, we wanted to examine whether the age of immigration altered the relationship between immigrant status and nonviolent and violent antisocial behavior. We contrasted these relationships among individuals who had immigrated before the age of 13 and after the age of 13.
Controlling for all the same factors presented in our main findings, immigrants who came to the United States at the age of 12 or younger were significantly more likely to report involvement in at least one of the violent (AOR=2.01, 95 % CI=1.87–2.15) or nonviolent (AOR=1.80, 95 % CI=1.71–1.89) antisocial behaviors as compared with immigrants who arrived at the age of 13 or older.
However, when compared to native-born Americans, immigrants who arrived as children or arrived at the age of 13 or older are still significantly less likely to take part in violent and nonviolent antisocial behavior than Native-born Americans, though the latter group begins to somewhat resemble the native-born behaviorally.
Finally, for all immigrants regardless of age, we estimated what each year in the US translates to with respect to an increased probability of reporting an antisocial act. Results showed that each additional year an immigrant has lived in the United States is associated with a 1.9 % increase in the likelihood of violence and a 0.9 % increase in the likelihood of nonviolent antisociality.
