If the number of employed workers equals 200 million and the number of unemployed workers equals 20 million, the unemployment rate equals 9%.
The unemployment rate is the percentage of the labour force that is unemployed.
The unemployment rate = (number of unemployed people / total labour force) x 100
Total labour force = 200 million + 20 million = 220 million
(20 / 220) x 100 = 9%
