two stacked bar charts  4_6

 

IV.6: In-Use Tickets by Provider Type - Consists of two stacked bar charts, one for each phase, that show the distribution of in-use Ticket assignments by provider type, by month for the period February 2002 through August 2003. In both phases, the percentage of in-use Tickets assigned to SVRAs increased over time, and the percentage assigned to ENs declined. In Phase 1, 82 percent of in-use Tickets were assigned to SVRAs in February 2002. The SVRA assignment rate rose to 87 percent in March, fell to 81 percent by May, and then gradually increased to its highest level, 91 percent, in August 2003. In Phase 2, 76 percent of in-use Tickets were assigned to SVRAS in November 2002. As in the Phase 1 states, the Phase 2 assignment rate initially fell, to 68 percent in December, and then gradually increased, to 82 percent in August 2003. In both phases, the time-patterns of the percentage of in-use Tickets assigned to ENs mirrored the SVRA rates just cited. That is, the EN assignment rate was initially relatively low, rose slightly, and then fell to a level below that initially observed.
