Methods used by National Sample Survey Organization (NSSO) to collect data for calculating poverty.
Mixed Reference Period (MRP):
- Since 1999-2000, however, data are being collected according to MRP. Under this method, data on five less-frequently used items are collected over a one-year period, while sticking to the 30-day recall for the rest of the items. The low-frequency items include expenditure on health, education, clothing, durables etc. Currently, all poverty line data are compiled using the MRP method. These include the most recent estimates by the Suresh Tendulkar and Rangarajan Committees.
Modified Mixed Reference Period (MMRP):
- In this method, for some food items, instead of a 30-day recall, only a 7-day recall is collected. Also, for some low-frequency items, instead of a 30-day recall, a 1-year recall is collected. This is believed to provide a more accurate reflection of consumption expenditures.
Uniform Reference Period (URP):
- Up until 1993-94, the poverty line was based on URP data. This involved asking people about their consumption expenditure across a 30-day recall period. In other words, the information was based on the recall of consumption expenditure over the last month alone.
