Prisoners in custody summed from individual prison reports of prisoner inspectors to county-level totals, by decade, excluding 1790 and 1800. Totals exclude prisoners held in hulks. Matching prisons across years in prison inspectors’ reports is difficult because of vague and inconsistent prison descriptions.
