 Social disorganization theory has been instrumental in establishing the notion that stable, culturally homogeneous communities have lower rates of delinquency and crime regardless of race.Phillippia Simmons reports that many of the studies which have investigated intra- and interracial crime seek to explain this through a theory of macrostructural opportunity which states that interracial violence is primarily a function of opportunity and access.According to this theory, intraracial crime rates remain relatively high due to the fact that much of the US remains residentially segregated.
