The latest USSC Booker data

I am very pleased to see a new quarterly update with the latest, greatest post-Booker sentencing data available at this link over at the US Sentencing Commission’s Booker webpage.  Here’s how the USSC describes this data:

Quarterly Sentencing Update (Published March 7, 2007): An extensive set of tables and charts presenting cumulative quarterly data on cases sentenced in fiscal year 2007. The numbers are prepared using data sentenced by close-of-business on December 31, 2006 and received, coded, and edited by the Commission by February 27, 2007.

I am about to head into a faculty meeting, and this data report makes for great multi-tasking materials.  I’ll update this post later if any really suprising numbers jump out of this new data snapshot.

UPDATE:  Based on Figure C in this report, it appears that average sentences after Booker continue to rise, and may have experienced a (statistically significat?) up-tick from October 1 to December 31 2006.  Also, the circuit-by-circuit variations in prosecutor-inititated and judge-initiated below-range sentences are quite intriguing.
