Kurt Metzger, research director for CULMA's Center for Urban Studies, says metro Detroit\'s labor force is older than that of Chicago, Atlanta or Phoenix. About 22 percent of Detroiters are between the ages 45-64 and are nearing retirement. Metzger says there\'s a real concern that when baby boomers leave the work force our economy could sustain crisis levels. \"In southeastern Michigan, we have smaller numbers of younger people and they will not be able to keep up with the job demand.\"
