差距主要是由于劳动力使用不够密集。 欧元区妇女、最大以及最年轻年龄组的就业率要低于美国，工作时间更少，而且更为重要的是，失业率更高。
The bulk of the shortfall is due to less intensive use of labor: employment rates for women and for the oldest and youngest age groups are lower in the euro area than in the US, working hours are far fewer, and, least significantly, unemployment rates are higher.
