The Florida Bureau of Economic and Business Research reported that Florida for the first time since 1946 population saw it population shrink.

We had reported in January that increasingly people were no longer choosing Florida as the Best State to Retire. The Internal Revenue Service reported that more than 50,000 fewer tax returns were filed in Florida since 2005.  See Florida Losing Population for more on the IRS filings and January report.
The director of the University of Florida's Bureau of Economic and Business Research Stan Smith said the population dropped by 58,000 people between 2008 and 2009. This is the first decline since large numbers ofmilitary personnel left the state in 1946 after World War II.

Florida has become less attractive to many people on fixed incomes due to its expensive cost of housing particularly in South Florida and high real estate taxes and property insurance.

Tennessee, Georgia, North and South Carolina have become attractive choices as Best States to Retire.  Florida will not turn around quickly as many people on fixed incomes are still looking elsewhere.  Tennessee has the lowest cost of living in the nation.  See List of Cost of Living by State
If you are looking for a Best Place to Live or Retire, Florida has lost some mojo.
