(3) The NSSO used two methodologies—Uniform Recall Period(URP) consumption distribution and Mixed Recall Period (MRP)— in its sample survey data on household consumer expenditure (NSS 61st Round).As a result, two different consumption distributions for the year 2004-05 were obtained. The first one from the consumption data collected using 30-day recall period(also known as reference period)for all the items. The other distribution was obtained from the consumer expenditure data collected using 365-day recall period for five infrequently purchased non-food items, namely, clothing, footwear,durable goods, education and institutional medical expenses and 30-day recall period for the remaining items. These two consumption distributions have been termed as Uniform Recall Period (URP)consumption distribution and Mixed Recall Period (MRP)consumption distribution respectively.
