majority of the prison population in the US comprise only 2.4% of the UK. I'll point out another statistic which doesn't look good for our incarceration rates, regardless of the racial demographic argument you're making: Half of all persons incarcerated under state jurisdiction are for non-violent offenses, and 20% are incarcerated for drug offenses, in State prisons. Federal prison percentages are higher.
