For Denmark, the Retail Trade Index serves to analyse and explain the development in turnover within the different sectors of retail trade, which is the important part of private consumption. Monthly from 2000.
The retail sales index describes 43 industries and 3 main product categories of food and other groceries, clothing, etc., and other consumer goods. The statistics are based on data collected from major retailers.
