The retail trade index measures the monthly evolution of the turnover at current prices of enterprises with retail sale outlets. With effect from January 2013 the indices are calculated with reference to the base year 2010 using the Ateco 2007 classification (Italian edition of Nace Rev. 2). In September 2015 the seasonally adjusted retail trade index decreased by 0.1% compared with August 2015 (-0.1% for both food and non-food goods). The average of the last three months compared to the previous three months increased by 0.2%. The unadjusted index increased by 1.5% compared with September 2014. (full story)
