This map below from the Gallup organization shows the results from its newly released Global Employment Index. The Index is based on Gallup data on workers that are employed full time for an employer, underemployed, and unemployed; it charts these employment trends by global region. An interactive map can be found here.
Gallup's analysis finds a close association between economic development (measured as GDP per capita) and full time work, a negative relationship between economic development and underemployment, but no relationship between economic development and the rate of unemployment.
Unemployment remains a persistent problem in the U.S. and other advanced nations, but perhaps a closer consideration of full time work and underemployment will yield another, even more useful set of insights.
