New Orleans is the largest market affected, adding five more counties and moving up from market #52 into the top 50 at #45.
The new rankings are approximate and their final new rankings will not be official until the Fall 2011 metro rankings are announced later this year.
Estimated Fall 2011 Metro ranks are based on Nielsen Claritas population estimates projected to January 1, 2011. The final Fall 2011 Metro ranks may change when Arbitron implements this year's population update, which is scheduled to include population estimates based on Census 2010 projected to January 1, 2012. Other Arbitron market changes may also affect final ranks. For more information regarding Arbitron and Census 2010, see the White Paper.
