Report for Phase II of the Medicaid Undercount Project (SNACC). In this phase data were merged from the Medicaid Analytic Extract (MAX), MSIS, the Current Population Survey (CPS), the Person Characteristic File (PCF), and the Master Address File Auxiliary Reference File (MAFARF). Once matches/non-matches between the MSIS and CPS were determined, the matched records were supplemented with information from the MAX and examine why there were discrepancies between MSIS records of enrollment and CPS reports of Medicaid coverage. The MAFARF and PCF are used to augment the analysis. March 2008.
