Technical Working Paper: Creation of the 2012 Baseline of the 2009 MATH SIPP+ Microsimulation Model and Database.

This report documents the process of updating an existing microsimulation model and database designed to help policymakers measure the effects of policy reforms to the Supplemental Nutritional Assistance Program (SNAP). The updated model enables users to estimate the effects of policy changes based on the most current SNAP eligibility rules (fiscal year 2012), rather than the rules in effect when the data were collected (fiscal year 2009). The updated model includes additional enhancements, including expansions to the simulation of public assistance.
