In a survey of WIC participants, a telephone survey was conducted and fifty percent of the respondents were asked to participate in an in-home survey. A number of respondents to the telephone survey declined to participate in the in-home survey. The presence of a number of variables in the telephone survey lends itself to weight adjustments using either propensity weights or propensity categories. Variables associated with the in-home survey variables were used to predict responding to the survey. Two methods of adjustment were compared with results not adjusting for nonresponse. In addition, a variable from the telephone survey was used to simulate an in-home response so as to compare estimates using the two procedures with actual estimates from the telephone survey.
