Why are racial gaps in US arrests and imprisonment narrowing?
Core argument: Black–White disparity in drug-offence prison admission rates fell from 12 to 1 in 2000 to 2.9 to 1 in 2019, attributed almost entirely to a 75% drop in the Black prison admission rate for drug offences.
From their respective peaks [2000 for whites, 2006 for blacks], prison admission rates for violent crime fell 20% for Whites and 43% for Blacks. [Because UCR crime totals do not identify offender race, the authors use the National Incident-Based Reporting System (NIBRS), which records offender race as reported by victims, witnesses or police, to allocate national violent-crime totals by race. NIBRS contains about three times as many violent offenders as arrestees. As a check on crimes not reported to police, they use National Crime Victimization Survey victim reports; results are similar.] [Recorded violent crime fell 18% for Whites and 47% for Blacks See Table 2]. For Whites, the decline in prison admissions is primarily a function of a decline in crime and arrests, with case processing dampening the decline. For Blacks, the decline in violent prison admissions is exclusively attributed to a 47% reduction in violent crime, as policing and case processing trends worked against an otherwise larger decline. [Arrests per crime and prison admissions per arrest both rose slightly; See Table 2].
