Census of Juveniles on Probation - Sneak Preview of OJJDP Data

A few weeks ago, I announced here that the Office of Juvenile Justice and Delinquency Prevention (OJJDP) had completed its first-ever "Census of Juveniles on Probation" (CJP). Since the report's not done, however, I didn't have any data to share.
The report still isn't done, but it turns out that some preliminary data from the juvenile probation census is available online from George Mason University, where the work is being done.
Curious about the survey? You download the 2009 survey sent to juvenile probation offices in PDF format here.  Next, you can review answers to some "frequently-asked questions," such as number of youth on probation by state, or the ratio of youth on formal probation to those on informal probation. 
In addition, you can also view graphs for 18 pre-set reports based on the juvenile probation data, like the one pictured here for drug offenses. You can see nationwide snapshots of juvenile probationers broken down by age, race/ethnicity, gender and offense category, and many more. Just bear in mind that the data isn't final and may change.  (Hat tip to Lore Joplin.)
