The Fall and Rise of Racial Inequality in London Homicides: a Challenge for Policing by Consent

Research Question How have London’s racial and demographic disparities in homicide victimisation rates changed in 2 decades of the twenty-first century, with what implications for policing by consent? Data We collected Metropolitan Police Service homicide victimisation counts in London for each financial year (April through March) so far in the twenty-first century, by race, gender and age. We also collected the estimated residential population size of those groups from the 2001 and 2011 Census results. Methods We divided the number of homicides each year in each demographic category by the estimated population size of that category, and then computed victimisation rates per 100,000 for each of the 21 years. We plotted trends in the rates of each group over time, whilst calculating ratios between victimisation rates of Blacks and Whites, and of South Asians and Whites, in each year. Findings Over the past 2 decades in London, Black homicide victimisation rates have fallen by almost half, but they remain about 5 times higher than homicide victimisations of Whites and South Asians. Inequality of homicide rates between Black and White victimisations declined substantially, but then became worse: the most recent 5 years showed 19% more inequality than in the century’s first 5 years. Three major changes in homicide inequalities have occurred since 2001: (A) The total Black homicide victimisation rate dropped by 71% from 2001 to 2014; (B) homicides of Blacks then increased by 92% in the 5 years to 2019–2020, whilst the White victimisation rate remained unchanged; (C) from 2019 to 2022, Black victimisation rates declined again by 27%, whilst White rates also declined, by 26%. Young Black males aged 16–24 were 10 to 20 times more likely than White counterparts to become homicide victims in 2017–2022. Yet Black female homicide victimisation dropped by 82% over 21 years. Female inequality reduced from up to 400% higher for Black females than Whites at the beginning of the century to 67% higher in the most recent 5 years. For Asians of all ages, inequality of homicide victimisations to Whites disappeared by 2022. Inequality persisted between young Asian males and young White males. Conclusion Changes in London’s racial inequality in homicide victimisation are both substantial and volatile. Understanding their fall and rise may help police to renew and sustain reductions of racial inequality in risks of violence. Learning lessons about what police may have done to cau
