But over the last two years, both have lost their jobs. Her unemployment check ran out in the spring, leaving them to subsist on his jobless benefits alone, about $1,500 a month.
The Blanco's shattered fortunes have supplied them an unwanted new status, one they share with millions of suburban households in a nation previously accustomed to thinking of suburbia in upwardly mobile terms: They are poor.
They are officially so according to the federal government's definition, which sets the poverty line for a family of five at an annual income of $26,023 or less. It is viscerally true when one sees how Blanco, 28, now spends her day. She takes her four-year-old son to a county-operated Headstart program, free preschool for the poor. She forages for clothes at thrift stores. She scrounges for coupons to keep her family fed.
"We were doing well," Blanco says, dabbing at reddening eyes with a tissue, trying to make sense of events that contradict her understanding of what is supposed to happen to people who work, save and provide for their children. "My husband and I would go out to eat without even thinking about it. We bought shoes. When I needed a bra, I went to Victoria's Secret. Now we're like, 'Which Goodwill is having a sale?'"
They have applied for food stamps and the cash assistance program familiarly known as welfare, crossing a previously unimaginable threshold: For the first time in her life, Blanco -- a self-possessed, confident, intelligent woman who still carries herself like someone who used to work in an office -- has entered the ranks of those in need of public assistance.
"It's a horrible feeling," she says, tears staining her face. "There's pride. I don't show my kids that we're hurting, but it hurts me. It makes me feel like I'm failing as a parent. It's embarrassing."
Despite the typically urban associations evoked by talk of poverty in America, Blanco is the face of an emerging segment of the nation's poor now growing faster than any other. Though cities still have nearly double the rate of poverty as suburban areas, the number of people living in poverty in the suburbs of major metropolitan areas increased by 53 percent between 2000 and 2010, as compared to an increase of 23 percent among city-dwellers, according to a Brookings Institution analysis of recently released census data. In 16 metropolitan areas, including Atlanta, Dallas and Milwaukee, the suburban poor has more than doubled over the last decade.
The swift growth of suburban poverty is reshaping the sociological landscape, while leaving millions of struggling households without the support that might ameliorate their plight: Compared to cities, suburban communities lack facilities and programs to help the poor, owing to a lag in awareness that large numbers of indigent people are in their midst. Some communities are wary of providing services out of fear they will make themselves magnets for the poor.
In the suburbs, getting to county offices to apply for aid or to food banks generally requires a car or reliance on a typically minimal public transportation network. The same transportation constraints limit working opportunities, with many jobs potentially beyond reach and would-be employers reluctant to hire people who lack their own vehicles.
