The impact of medical out-of-pocket expenses (MOOP) on alternative poverty rates is estimated in this paper. Different types of imputations based on data from the Medical Expenditure Survey and the Consumer Expenditure Survey are used to determine the quality of the reported amount of MOOP in the Survey of Income and Program Participation (SIPP). Comparisons are made of the imputation for MOOP by focusing on the average dollar amount imputed to families and the resultant growth in poverty. Significant differences were found depending on the imputation strategy. Overall, the reported MOOP value in SIPP performed better than expected.
