Column (5): source code: Consumption of an item during the last 30 days may be made out of one or more of several possible sources: namely, purchase, home produce, exchange of goods and services, gifts or charities, and free collection. The source from which the item has been obtained and consumed by the household will be recorded in code.
Code 3 will be applicable if consumption is made out of both purchase and home-grown stock but not from any other sources. Any other combination of sources will get code 9. Consumption out of transfer receipts or commodities received in exchange of goods and services will also get code 9. Note that some food products such as muri are often made in the home by processing of foodgrains such as rice. In such cases, the source of consumption will be "purchase" if the basic foodgrain (in case of muri, rice) is purchased; the source of such products will be "home-grown stock" only if the foodgrain from which they are made is itself home-grown.
Home processing of food: Some food items listed in Block 5 may be prepared in the home from other food items listed in Block 5. For example, ghee (item 164) may be prepared in the home from milk: liquid (item 160). Pickles (item 305) may be prepared in the home from chillies, mangoes, salt, etc. In all such cases the question of where to record the consumption of such food preparations is answered as follows: against the ingredient items. Thus consumption of purchased ghee (or ghee received as gift, say) is recorded against "ghee" but that of home-made ghee against "milk: liquid"; consumption of purchased muri is recorded against "muri" but that of home-made muri against "rice"; consumption of purchased pickles is recorded against "pickles" but that of home-made pickles against "salt", "mango", "chilli", etc.
It follows from the above that source codes 2 (consumption from home-grown stock only), 3 (consumption from both purchase and home-grown stock) and 4 (consumption from free collection) are not permissible for items of Block 5 such as chira, muri, curd, ghee, butter, ice-cream, etc., which are created by processing of other items of Block 5 (rice, milk, etc.).
Some home-made items such as pickles and ghee may be stored in the home for a number of months before they are consumed. Data collection on consumption during any particular month becomes difficult in such cases. For simplicity of data collection, therefore, the ingredients may be regarded as consumed at the moment when they are used up in the process of preparation of the final food product. This applies to all items of Block 5 which may be prepared in the home from other Block 5 items. It follows that home-made items such as ghee and pickles, if received by the sample household as gift from the household which prepared the item, and subsequently consumed, should not be accounted as consumption of the sample household. This procedure is a departure from the consumption approach otherwise followed for food items.
