The retail trade index measures the monthly evolution of the turnover at current prices of enterprises with retail sale outlets. Since January 2009 the indices are calculated with reference to the base year 2005 using the new Ateco 2007 classification (Italian edition of Nace Rev. 2).
In September 2012 the seasonally adjusted retail trade index increased by 0.1% with respect to the previous month (0.2% for food goods and 0.0% for non food goods). The average of the last three months compared to the previous three months increased by 0.1%.
The unadjusted index decreased by 1.7% with respect to September 2011.
