<h1>India Updates WPI Base Year to 2011-12: More Items, Improved Accuracy, and New Food Index to Track Inflation.</h1> The government has updated the base year for the All-India Wholesale Price Index (WPI) from 2004-05 to 2011-12 to better reflect economic changes and improve the index's accuracy. This aligns WPI with other economic indicators like GDP and IIP. The revised WPI includes 697 items, up from 676, and increases price quotations from 5,482 to 8,331. Indirect taxes are excluded, aligning WPI closer to the Producer Price Index. A new Food Index tracks food inflation, and seasonality for fruits and vegetables is updated. Data collection methods have been modernized, incorporating international standards and technology.
