Does anyone know if (or when) this map will be updated? Some of the states have data from 2006-2009. It would be great to get more-current information and see the rates now, compared to then.
I looked at that page. It clearly says that the rates were drawn from the most recent data available from HCUP. You complaint should be directed to HCUP. The data seems to be issued in three year increments, so I would not expect any updates until 2012, or even 2013 since it takes time to tabulate this data.
I found it interesting that three states, WA, NV and AZ have lower rates than the fabled California. Nevada's rate is just 13%.
