Using California's Monthly Arrest and Citation Register (MACR) data collected by the California Department of Justice for the years 1991-1996, this study examined odds of arrest for various violent and lucrative type offenses, across seven different Asian ethnic groups. To avoid selection bias, African Americans, Hispanics and Native Americans were also included in the analysis. Logistic regression models were fitted to the MACR data. Consistent with theoretical hypotheses, the authors found that Southeast Asian immigrants were more likely to engage in criminal activity than their white counterparts and more established Asian groups. Logistic regression results revealed that Southeast Asians, in particular Vietnamese, were over-represented in every arrest category, while non-refugee Asian groups were considerably underrepresented in arrests. Cambodians, Laotians, and Vietnamese were at significantly higher odds of arrest for crimes that tended to produce financial gain, such as theft, car theft, and petty theft. The authors suggest that their findings on Southeast Asians may in part reflect the unique nature of the immigration of members of this group to the U.S., and the multiple disadvantages that they continue to experience, for example, low human capital, lack of English proficiency, and ethnic prejudice and discrimination. Results suggest the need for more programs aimed at assisting Southeast Asians refugee immigrants with their transition into American society.
