An important measure of the Food Stamp Program’s performance is its ability to reach the people it is meant to serve. This report presents estimates of the food stamp participation rate among eligible working poor persons in each State. Working poor persons are defined as individuals living in house holds in which at least one member had earnings from a job. The participation rates are presented for an average month in fiscal year 2002 and the two previous fiscal years. These estimates can be compared to the State food stamp participation rates previously released for all eligible individuals in Reaching Those in Need: State Food Stamp Participation Rates in 2002 (March 2005).
