When Birds of a Feather Don't Flock Together: A Macrostructural Approach to Interracial Crime

초록

The greater prevalence of intraracial crime to interracial crime is a common finding in criminology. This issue is best understood when specific crimes are studied from a proper theoretical basis. We argue that variation in rates of cross-racial crime is explained by homophily bias, reflected in residential segregation, in conjunction with the motivational mindset of an offender, specifically whether a crime is instrumental or expressive in nature. We hypothesize that homophily bias is stronger in expressive crimes than it is in instrumental crimes. Using the National Incident-Based Reporting System (NIBRS) for 2009 and 2010, we analyze robbery and aggravated assault as instrumental and expressive crimes, respectively. The analyses show that racial residential segregation increases, as expected, the relative frequency of black intraracial assault to black interracial assault, whereas it does not affect the relative frequency in robbery. Contrary to our hypothesis, however, the same variable shows little effect on the relative frequency of white intraracial to interracial assault. We give possible explanations as to why white crimes are insensitive to residential segregation.
