Mortgage interest deduction by state at Tax Policy blog

Nick Kasprak over at the Tax Policy Blog (here) has a map of the mortgage interest deduction by state (2009 data).  The map shows the percentage of returns claiming mortgage interest deductions.  Mississippi is listed in the "bottom ten states" with 17.7% (ranked 47th) of the returns for 2009 claiming a mortgage interest deduction.  States in the "top ten" saw over 30% of the 2009 returns claim a mortgage interest deduction.
