According to the data released from the Central Statistics Office (CSO), retail inflation for the month of January has declined to 2.05%. This decline has been primarily due to a) sustained decline in food prices and b) a sharp decline in energy prices.

There are four types of CPI: a)CPI-IW (Industrial Worker), b) CPI-UNME (Urban Non-Manual Employees), c) CPI-AL (Agricultural Labourers) and d) CPI-RL (Rural Labourers)
RBI has adopted CPI as the key measure for determining inflation situation of Indian economy, on recommendation of Urjit Patel Committee.
