Answer: Option C
Explanation: The unemployment rate refers to the proportion of the unemployed workforce, calculated as a percentage.
This is considered as a lagging indicator, which means this normally goes up or down in the midst of response to changing circumstances instead of predicting them. The unemployment rate could be expected to increase when the economic situation is in bad condition and job opportunities are scarce.
In order to evaluate the jobless rate, the amount of unemployed individuals is measured by the number of working and unemployed individuals in the total labor force.
