The number of people in jail or prison in the United States hit another record at the end of last year, according to a report from the US Department of Justice's Bureau of Justice Statistics released Thursday. According to the report, Prisoners in 2007, 2,293,157 people were behind bars at the end of last year, roughly two-thirds of them serving prison sentences and one-third doing jail time.

Drug offenders made up 19.5% of all people doing time in the states, or roughly 400,000 people. In the federal system, drug offenders account for well over half of the 200,000 prisoners (those numbers are not included in this report), bringing the total number of people sacrificed at the altar of the drug war to more than half a million.

Parole and probation violators accounted for about one-third of all new prison admissions last year. It is unclear how many violations were for drug-related reasons, but that number is undoubtedly substantial.

The imprisoned population continued to grow last year, albeit at a marginally slower rate than the decade as a whole. The number of those imprisoned grew by 1.8% last year, down from 2.8% in 2006, and slightly lower than 2.0% a year average since 2000.

The population behind bars continued to grow at a faster rate than the population as a whole last year. The number of people imprisoned per 100,000 population -- the imprisonment rate -- rose from 501 in 2006 to 506 last year. It was 475 per 100,000 in 2000. Since 2000, the number of people behind bars increased by 15%, while the US population increased by only 6.4%.

The prison populations in 36 states and the District of Columbia increased during 2007. The federal prison population experienced the largest absolute increase of 6,572 prisoners, followed by Florida (up 5,250 prisoners), Kentucky (up 2,457 prisoners) and Arizona (up 1,945 prisoners), resulting in 58.7% of the change in the overall prison population. Kentucky (12.3%), Mississippi (6.5%), Florida (5.6%), West Virginia (5.6%), and Arizona (5.4%) reported the largest percentage increases in their prison populations.

The prison populations in the remaining 14 states decreased. Michigan's (1,344) and California's (1,230) prison populations experienced the greatest absolute decrease, while Vermont (down 3.2%), Montana (down 2.8%), Michigan (down 2.6%), and New Mexico (down 2.6%) prison populations had the largest percent decreases.

America's position as the world's leading jailer, in both absolute and per capita terms, remains unchallenged, and the war on drugs is playing a significant role. Interestingly, the BJS report comes one day after a study from the Center on Budget and Policy Priorities reported that 43 states face budget shortfalls next year. As for the federal budget deficit, well, who can even keep up with that?
