Family Food Expenditure Survey, 2001 [Canada]: Summary Household File

<p>These public-use microdata files contain information collected via the Food Expenditure Survey (FOODEX) in 2001. The Food Expenditure Survey is a companion of the Survey of Household Spending which provides detailed information on all household expenditures, but only an overall estimate for food. The 2001 Survey of Household Spending was conducted in January, February and March 2002.</p> <p>The primary reason for collecting food expenditure data is to monitor and periodically update the weights used in the computation of the Consumer Price Index (CPI). In addition to this, food expenditure data classified by variables such as income, household type and province, provide the basis for a variety of analytical investigations of the food purchasing habits of households in Canada. For example, the survey data are used for market analysis and nutritional studies.</p> <p>There are two files to this survey; the Detailed Expenditure File and the Summary Household File. The household file provides summary level food category information at a weekly level (either week one or week two or both if available) and also socio-economic characteristics of the household. The food expenditures are presented by specific food item purchased from stores, locally and on day trips. Records may be linked using the household "identification number".</p>
