Changes In The Data On Race Collected And Reported By States And Federal Agencies
"Comparisons of changes in the racial composition of prison populations over time are constrained by new data collection methodologies. Following guidelines provided by the Office of Management and Budget, beginning in 2005 BJS estimated racial composition of the prison population separately for persons identifying with one race (97%) and those identifying with two or more races (3%). These guidelines have reduced the number and percent of persons identified as non-Hispanic white and non-Hispanic black prisoners. In addition, administrative data on the race and Hispanic origin of prisoners reported to BJS by corrections officials also overstate the number of non-Hispanic white and black prisoners and understate the number of Hispanics and persons of two or more races.2
"Both administrative and estimated data indicate an overall decline among black prisoners from 2000 through 2006. The 2006 administrative data show a decline from 46.2% to 41.6%, while the estimated data indicate a decline from 42.4% to 37.5% (table 8)."
"2 Some jurisdictions are not able to report Hispanics or persons of two or more races as a separate category as requested under OMB guidelines."
