From 1994 to 2011, the rate of all burglaries (attempted and completed) decreased 56 percent, from a peak of 63.4 to 27.6 victimizations per 1,000 U.S. households. The number of burglaries experienced by U.S. households declined 47 percent, from about 6.4 million burglaries in 1994 to about 3.4 million in 2011
I'm not surprised that median went up, I would expect that as a side effect of a significant drop in the rate.
