This paper describes in some detail the challenge of changing and moving the measurement of poverty in the CPS to measuring poverty in the SIPP. Considerable detail is presented on the different design and collection methods of each element of a poverty measure. These differences have important effects on the estimation of alternative poverty measures. We also describe differences in measurement methods, and this is an area where more work needs to be done. All of estimates for the SIPP describe the survey in its present format. It is important, however, to consider the effects of the redesign of the SIPP on the calculation of poverty statistics.
