From page 421...
... The scale of a penal system is usually measured by an incarceration rate that expresses the number incarcerated per 100,000 of the resident population. The annual rates are usually formed with census population counts and intercensus estimates.
From page 422...
... Data on inmate totals come from the Sourcebook of Criminal Justice Statistics Online.1 Data for federal and state inmates 1982-1984 and 1986-1989 were provided by BJS. Jail counts are for the last business day in June; state and federal prison counts are for December 31 of the year.
From page 423...
... for 1972-2010.3 Because the CPS is a household-based, noninstitutional sample, we constructed a series of civilian incarceration rates in which the weighted population totals from the March CPS were adjusted to include inmate totals from BJS, as outlined in Pettit (2012) and Pettit et al.
