should be made clear to the public that any poverty measure needs to be periodically evaluated, and perhaps improved, to incorporate new information or improved methods. Timothy Smeeding and Rebecca Blank also advocated continuing the current poverty measure time series to have some level of continuity in poverty statistics.

FUTURE RESEARCH

In addition to the topics for future research already mentioned, some participants indicated that further research could be helpful on some of the elements discussed above. Thus, some of the participants advocated developing improved methods for incorporating geographic adjustments to the thresholds, and others supported more research on whether equivalence scales should incorporate more than three parameters. If SIPP data rather than CPS data are to be used as the main source for poverty statistics, participants said that research is needed on the attrition problems in the SIPP. Some participants repeated their interest in future research on the use of an alternative unit of analysis other than the official family, and the feasibility and practicality of accounting for wealth and household production in a new poverty measure.
