Citizenship and Punishment: The Salience of National Membership in U.S. Criminal Courts.

When compared to research on the association between immigration and crime, far less attention has been given to the relationship between immigration, citizenship, and criminal punishment. As such, several fundamental questions about how noncitizens are sanctioned and whether citizenship is a marker of stratification in U.S. courts remain unanswered. Are citizens treated differently than noncitizens-both legal and undocumented-in U.S. federal criminal courts? Is the well-documented Hispanic-white sentencing disparity confounded by citizenship status? Has the association between citizenship and sentencing remained stable over time? And are punishment disparities contingent on the demographic context of the court? Analysis of several years of data from U.S. federal courts indicates that citizenship status is a salient predictor of sentencing outcomes-more powerful than race or ethnicity. Other notable findings include the following: accounting for citizenship substantially attenuates disparities between whites and Hispanics; the citizenship effect on sentencing has grown stronger over time; and the effect is most pronounced in districts with growing noncitizen populations. These findings suggest that as international migration increases, citizenship may be an emerging and powerful axis of sociolegal inequality.
