(AP) Through the voices of its people, the map shouts.

From Atlanta, Ga., listen to Marian Chamberlain, 65, jobless, and no longer eligible for unemployment: "I will never be able to retire."

From Shakopee, Minn., listen to Bruce Paul, 56, a vintage car mechanic laid off in January and unemployed for the first time since Richard Nixon was president. Today he and his wife spend their days in the public library to reduce energy costs at home. "You go out and they say, you know, you need a resume. And I say, `A resume? What's that?'"

From Broomfield, Colo., listen to U.S. Marine and construction worker Simon Todt, 27, a combat-arms specialist who returned from three tours in Iraq only to be laid off from his construction job in December. He smiles wanly as he sums up his situation: "There's not a big calling in the civilian world for explosives."

The republic is brimming with Americans like these. And the Associated Press Economic Stress Map helps us find their voices and tell their stories.

For generations, maps have told tales that words and numbers alone cannot. Maps guided us to the New World, helped us navigate from its edges into its interior. Vague, undefined maps showed Lewis & Clark where to go next _ and in turn gave us fresher, more accurate maps that fueled further explorations. Maps outlined the frontier for settlement and showed us where to find the silver, the gold and the coal that made us prosperous. Computer mapping helps businesses expand, prosper and find new customers.

The interactive Stress Map offers insight into the American recession, translating it into misery and geography using an equation, the Stress Index, that shows us _ state by state, county by county _ just how uncertain and battered around we actually are. It takes the numbers, the pronouncements, the big plans for recovery and illustrates what they mean on Main Street USA, or what passes for it in 21st-century American communities.

The Stress Index synthesizes three complex sets of ever-evolving data. By factoring in monthly numbers for foreclosure, bankruptcy and _ most painfully _ unemployment, the AP has assembled a numeral that reflects the comparative pain each American county is feeling during these dark economic days.

Here are some fleeting examples of what the Stress Index tells us:

_The current recession spread like an epidemic from isolation to ubiquity, marching from sequestered pockets of foreclosure to a nationwide explosion of misery as unemployment overtook foreclosures as the dominant misfortune of this recession.

_Places with technology-based economies were recession-proof for a while but aren't now.

_Places with large numbers of government jobs _ state capitals, university towns, communities with concentrations of hospitals _ remain fairly recession-proof. These are places like Columbia, Mo.; Madison, Wis.; the Raleigh, N.C., area; and Athens, Ga.

_State government is not hurting that much _ at least, not yet.

_The regions we look to for our traditional sources of energy, for our coal and oil _ Wyoming, West Virginia and the like _ have generally not been hit as hard.

_While bankruptcy declarations are happening everywhere, they tend to be higher in the South because of such things as low wages, state laws that give power to creditors and a culture that's more familiar with the bankruptcy option.

_Among counties with 25,000-plus residents, no place has been hit harder than Elkhart County, Ind., and that 15 of the 20 American counties hit hardest by the recession in the past year are in six states _ Indiana, Ohio, Michigan, North Carolina, South Carolina and Tennessee.

The Stress Index is not merely a map of misery, though. When recovery comes, it can be a map of optimism as well, a welcome harbinger of better days approaching. Going forward, it can track the recovery we hunger for _ show us where it is poking its head up, where it is spreading and who it is leaving behind.

The map, and the numbers behind it, cannot tell us everything. No single number can track Americans' net worth, no monthly barometer indicates the pain factor of people who lost retirement funds, whose stocks vanished out from under them, who dutifully set aside nest eggs that now amount to little or nothing.

But it can help compare and contrast places, then find the people who breathe life into the numbers that characterize their regions and their hometowns. It can illustrate emerging trends _ why are certain areas starting to recover while others are lagging behind? _ and offer early hints to where the tightness of economic stress might be starting to loosen.

Where can we go with this map? It can carry us to Los Gatos, Calif., one of the high-tech regions that seemed to be escaping the worst of the recession but is now clawing to keep pace. It can point us toward Champaign, Ill., an example of the trend that communities with government institutions tend to be more recession-proof than other places.

It can highlight Burlington, N.C., where the manufacturing jobs that disappeared might never be coming back, and Myrtle Beach, S.C., where unemployment and foreclosures have locals wondering when the dividends of the American vacation economy will shine upon them once more.

There was a time, not so long ago, when the problem was that we didn't have enough information. Now, you can argue, we have too much _ dizzyingly so. And instead of being tasked with accumulating enough data to understand our world, now we spend our jumbled days shuffling through the information that's out there, struggling to make sense of it and harness it to improve our lives.

For the immediate future, the AP Economic Stress Map will attempt to do just that for the United States. AP reporters will be fanning out across the land, telling regular stories based on the monthly numbers _ stories of people like Ron Edo, 42, an aircraft maintenance worker from Temecula, Calif., who has sent out more than 1,500 resumes since he lost his job a year ago.

"Luckily I saved when I was young," he says. "My parents used to always tell me to save for a rainy day. And it's pouring."

There are many more like him. The map shouts _ and in doing so, points us to the stories of the most wrenching economic conundrum of our age.
