A new Census Bureau wall chart on the world's labor force shows that:
1. The world's "visible" work force will grow 35 percent by 2010.
2. Labor force counts by developing countries typically omit rural women. But this "invisible" labor force makes up 50 percent or more of the agricultural workers in many of these countries.
3. Only in Paraguay are women's wages higher than men's. No explanation is offered.
4. In poorer countries the elderly must usually continue to work past age 65.
