(CNN) More than one in seven Americans are on food stamps, but the federal government wants even more people to sign up for the safety net program.
The U.S. Department of Agriculture has been running radio ads for the past four months encouraging those eligible to enroll. The campaign is targeted at the elderly, working poor, the unemployed and Hispanics.
The department is spending between $2.5 million and $3 million on paid spots, and free public service announcements are also airing. The campaign can be heard in California, Texas, North Carolina, South Carolina, Ohio, and the New York metro area.
