This analysis is designed to provide estimates of the total food expenditures and expenditures on food groups1 for WIC households to assess the relative contribution of the WIC food packages to their food expenditures. Analysis reported in the phase I report focuses on the level and contributions of at-home and away-from-home food expenditures and the WIC food package to total food expenditures for three kinds of households: (1)

was used in constructing the final sampling weights. Each household was given a final sampling weight to be used in making the sample nationally representative of all non-nstitutionalized households in the contiguous United States, and i the analyses and standard errors account for the complex sampling design.

Nonetheless, they were included in the analysis to generate a representative "average" amount of food expenditures for all households, because, over the course of 1 month, households vary widely in the frequency and size of their food purchases and acquisitions. Among all households examined in the FoodAPS, 7 to 9 percent reported no FAH expenditures in the interview week (including 8.7 percent of WIC households)

Data were weighted in estimates of mean values and standard errors using the household weights; all standard errors account for oversampling and the complex survey design of FoodAPS.3 Mean food expenditures and food insecurity scores were compared using t-tests, and distributions of demographic and food insecurity data were compared using the Pearson chi-square statistic between WIC households and both types of non-WIC households (Rao and Scott, 1984)

The strengths and unique features of the data include being a nationally representative survey, sampling to represent SNAP participants and other households in three income groups, and having a sample with SNAP participation and expenditures verified through administrative records. The results of the committee's analysis show that, in any week of the month, an important share of WIC households redeem their WIC vouchers and, for these households, the value of the WIC foods is relatively high -- almost one-fourth of the value of the foods acquired for home use.
