Employment
The unemployment rate is the percentage of the total labor force (i.e., those who are either
working or actively seeking employment) yet to find work. The unemployment rate
measures the extent to which the economy is operating at full capacity. The unemployment
rate is a statistic related to workers only, but further insight into the strength of the economy
can be gleaned by examining the use of other factors of production. For example, analysts
also look at the factory capacity utilization rate, which is the ratio of actual output from
factories to potential output.

概括

失业率指尚未找到工作的劳动力占总劳动力（即正在工作或积极求职者）的百分比，用于衡量经济是否以最大产能运行。该指标仅涉及劳动者，但通过考察其他生产要素的使用情况（如工厂实际产出与潜在产出的比率——产能利用率），可进一步了解经济活力。
