Mississippi has dropped from its third-place perch as a gaming destination in 2009 to fourth, after Indiana.
Though both states saw their adjusted gross revenues from commercial gaming fall from 2008 to 2009, Mississippi's decline was greater.
Revenues in Mississippi dropped from $2.72 billion in 2008 to $2.46 billion in 2009, while Indiana's fell from $2.67 billion in 2008 to $2.58 billion in 2009.
Nevada and New Jersey continued to hold the top spots in 2009, reporting $9.76 billion and $3.9 billion, respectively.
Officials say the poor economy coupled with the proliferation of gaming destinations is partially to blame.
Indiana also reaped the benefit of a smoking ban in neighboring casino states.
