Consumption

Back to Constructed variables

IHDS asked a series of 47 questions about household consumption designed to estimate total household consumption expenditures (see the household questionnaire pages 19-21). These consumption questions were modeled on the short form of the National Sample Survey. The total expenditure is often used as the best measure of the household's current economic level. The first thirty questions, for more frequently purchased items, used a 30-day time frame while the remaining 17 items used an annual time frame. The variable, copc, reports expenditures on a monthly basis, so items co31-co47 were divided by 12 before being summed in the final variable.

Consumption is one of three basic measures of economic standing in IHDS. The others are household assets and income.

Total monthly consumption had to be calculated for the first fourteen consumption items from answers to the quantity and price questions (page 19 of the questionnaire). These totals are stored as co1x, co2x, ... co14x on the data file.

The first five consumption items (rice, wheat, sugar, kerosene, and other cereals) could be purchased in PDS (public distribution system) shops, purchased in the market, or (except kerosene) home produced. Total monthly expenditures for these items was calculated from the household's report of the quantity and price purchased from PDS shops plus the report of the quantity home-produced or purchased in the market times the reported market price. Market and home-produced quantities were calculated from the difference between PDS purchases and the total consumed.  

For the next nine items, the household could report either the quantity consumed and the market price, or the total value of the items consumed. Sometimes, interviewers reported all three values. In rare cases where all three values were reported there was a discrepancy (the total value did not equal the quantity times the price). In these cases IHDS used the quantity and price reports and disregarded the total value report.

The final consumption total was calculated as the sum of the constructed variables co1x to co14x, the monthly items co15 to co30, and one twelfth of the annual items co31 to co47. Items asked on annual basis, converted to monthly:
