This is the final report for the project, "Analysis of the Current Population Survey Data for Food Security and Hunger Measurement" conducted by Mathematica Policy Research, Inc. for FNS, beginning in 1997. The project provided USDA with technical support and statistical estimation work for analyzing the 1996 and 1997 data on food security collected in the U.S. Census Bureau, Current Population Survey (CPS) Food Security Supplement. More broadly, the work examined a number of analytic and empirical issues relevant to analyzing the first three years of CPS food security data available—those for 1995, 1996 and 1997.
