SSA Payment History Update System (PHUS) SIPP Event History Calendar

Administrative data from SSA Payment History Update System Records are matched to Survey of Income and Program Participation (SIPP) respondents, including all SSA program data collected prior to and following the SIPP data collection. The SIPP data for this matching included data from the Event History Calendar. The Event History Calendar was developed for the SIPP survey to develop month level data for each respondent during the reference period. Each wave of the SIPP survey covers 12 individual months in the reference year.
