In 2009, the Office of Management and Budget’s Chief Statistician formed an Interagency Technical Working Group (ITWG) that issued a series of suggestions to the Census Bureau and the Bureau of Labor Statistics on how to develop a new Supplemental Poverty Measure (SPM).2 Their suggestions drew on the recommendations of the 1995 report of the National Academy of Sciences (NAS) Panel on Poverty and Family Assistance and the extensive research on poverty measurement conducted over the past 15 years at the Census Bureau and elsewhere. The ITWG suggestions focused on the implementation of the new measure using the Current Population Survey Annual Social and Economic Supplement (CPS ASEC). The ITWG stated that the SPM will not replace the official poverty measure and will not be used to define program eligibility. The Census Bureau released preliminary research SPM estimates in November 2011, 2012 and 2013 (Short 2011, Short 2012, Short 2013).
