"Following a positive four-month run, our Florida index declined in December by 1.3 percentage points. The index components were mixed for the month, with improvement in exports, tourism, sales tax revenues and unemployment insurance claims countered by weaker payrolls and construction," said Robert Dye, Chief Economist at Comerica Bank. "Importantly, increasing state sales tax revenue in December bodes well for ongoing economic momentum in Florida. Real estate markets are firming across the state, which will be an important source of strength in 2013."

The Florida Economic Activity Index consists of seven variables, as follows: nonfarm payrolls, exports, sales tax revenues, hotel occupancy rates, continuing claims for unemployment insurance, building permits, and airline passenger deplanements.  All data are seasonally adjusted, as necessary, and indexed to a base year of 2008. Nominal values have been converted to constant dollar values. Index levels are expressed in terms of three-month moving averages.
