One consequence is an upending of the traditional pattern, in which middle-aged children take in an elderly parent. As $15-an-hour factory jobs are replaced by $7- or $8-an-hour retail jobs, more men in their 30s and 40s are moving in with their parents or grandparents, said Cheryl Thiessen, the director of Jackson/Vinton Community Action, which runs medical, fuel and other aid programs in Jackson and Vinton Counties.

Other unemployed or low-wage workers, some with families, find themselves staying with one relative after another, Ms. Thiessen said, serially wearing out their welcome.

“A lot of major employers have left, and the town is drying up,” Ms. Thiessen said of Jackson. “We’re starting to lose small shops, too  Hallmark, the jewelry and shoe stores, the movie theater and most of the grocery stores.”

Shari Joos, 45, a married mother of four boys in nearby Wellston, said, “If you don’t work at Wal-Mart, the only job you can get around here is in fast food.”

Between her husband’s factory job and her intermittent work, they made $30,000 a year in the best of times, Mrs. Joos said. Since last fall, when her husband was laid off by the Merillat cabinet factory, which downsized to one shift a day from three, keeping anywhere near that income required Mrs. Joos to take a second job. She works at a school cafeteria each weekday from 9:30 a.m. to 1 p.m and then drives to Wal-Mart, where she relaxes in her car before starting her 2-to-10 p.m. shift at the deli counter.

Her 20-year-old son went to college for two years, earning an associate degree in information science, but cannot find any jobs nearby. He still works at McDonald’s and lives at home as he ponders whether to move to a distant city, as most local college graduates must. Her 22-year-old son works at Burger King and lives with his grandparents  “that was his way of moving out,” Mrs. Joos said.
