Abstract:	While almost all types of surveys have suffered from increasing nonresponse in the last decade, surveys of low-income households present particular response issues. For example, some households do not have telephones, and of those who do, many do not have land lines. If those without telephones or with only cellular telephones have different response patterns than households with land lines, typical telephone-only survey estimates will naturally be biased. Low-income households also appear to be a relatively mobile group and therefore harder to locate if a list sample is being used. Again, if those who cannot be located differ in their responses than those who were located, bias will be introduced. A survey of low-income taxpayers was sponsored recently bythe IRS and conducted by Westat. We first describe the survey methods used in an attempt to maximize the response rates. We then describe the analysis done to evaluate the nonresponse bias in this particular survey, discuss potential adjustments that can be made based on the analysis, and make recommendations for future surveys of this nature.
