In this report we discuss our progress in deriving state participation rates for the working poor. We build upon recent studies examining national participation rates for socioeconomic and demographic subgroups and rates for states among the entire eligible population.

This report presents estimated participation rates for 2002 and revised estimates of rates for 1999, 2000, and 2001.

This report is the latest in a series of publications presenting estimates of the percentage of eligible persons, by state, who participate in the Food Stamp Program. This issue presents food stamp participation rates for states in an average month in fiscal year 2001 and for the two previous fiscal years. These estimates differ slightly from those reported last year because of the change in the reference period from the month of September to the average month across the fiscal year, and improvements in data and methods.
