Longitudinal monthly data from the Survey of Income and Program Participation (SIPP) enable researchers to examine key dynamic events, in the context of a wide range of information about the household. This paper examines the national survey context for the SIPP, provides some basic facts about the survey and its methodological issues such as attrition and seam bias, and discusses some of the remaining challenges the Census Bureau faces in the years ahead.
