Unemployment is the number of people who are willing to work and are actively seeking work but are unable to find it. The unemployment rate is the unemployed / total number of people in the labor force x 100.
In the above scenario, the unemployed is 3 million people. The others are either already employed, unavailable, unwilling or not seeking work.
The labour force comprises of those who are employed and unemployed, that is 80million + 3million = 83 million.
A complement is a good or service used in conjuncture with another good. Therefore, if there is a decrease in the demand for a particular good, its complements will also see a decrease in demand.
