Forty-five percent of Americans define themselves as middle class, according to an ABC News poll in 2010. Those polled generally agreed upon some basics of a middle-class lifestyle: They worked in stable jobs, owned homes in safe neighborhoods, owned at least one vehicle, saved a little for retirement and college tuition.

“That set of things is becoming increasingly unattainable for a lot of people,” said Amy Hanaurer, executive director of Policy Matters Ohio, who spoke to The Columbus Dispatch as part of the newspaper’s wide exploration of what it means to be middle class that was published last week.

The topic is a central and divisive one in Ohio, where presidencies have historically been decided and a current debate rages over Senate Bill 5, a piece of controversial legislation that limits the collective bargaining rights of public employees. Special-interest groups fighting the legislation all claim they’re working on behalf of the middle class.

As part of a five-day series, experts told The Dispatch that globalization has battered the nation’s manufacturing sector, which once formed the crux of Ohio’s middle class. The median wage has declined in Ohio more than any other state since 2000, according to census figures.

In the wake of that economic devastation, The Dispatch sought out to define the middle class. You can find out what they learned, how Ohioans have coped with the recession, how they’ve reinvented themselves and lowered their expectations.

The series raises important questions about how Americans view themselves in the aftermath of the Great Recession – and how they handle the ever-present fear of a double-dip recession on the horizon.
