Column (7): 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.
