This report examines data from the Current Population Survey in order to analyze trends in free and reduced price certification and participation in the National School Lunch Program during the period of 1993-1997. The data indicate that free certifications for NSLP as a percentage of CPS estimated eligibles have been increasing for several years and was 118% in 1997 (latest available). 

In the past, the Food and Nutrition Service (FNS) has relied on a series of large surveys to gather and compare information on food expenditures and food consumption among participants and non-participants to better understand the impacts of the Food Stamp Program (FSP) on the diet and nutritional status of program participants. Studies based on survey data, however, have a number of drawbacks, including the time and expense of collecting the survey data, sampling error, response bias, errors in respondent recall, and misinformation about what may have been purchased or consumed.
