- The Wholesale Price Index (WPI) in India is a key inflation indicator. It is calculated based on changes in the average price of a basket of goods at the wholesale level. - The WPI basket is divided into three major groups: Primary Articles, Fuel and Power, and Manufactured Products. - As per the current WPI series with the base year 2011-12, the approximate weights of these groups are: - Primary factured Products: 64.2% - Clearly, Manufactured Products have the highest weight among the three main groups. - "Food item" is not a major group itself but a category that appears within both Primary Articles (e.g., food grains, fruits, vegetables) and Manufactured Products (e.g., processed food products). Therefore, comparing a sub-category like "Food item" directly with main groups is not appropriate based on the standard WPI structure.
