Answer:
Step-by-step explanation:
From the given data, The unemployment rate is calculated to be 20%
What is unemployment rate?
This is the term that is used to refer to the rate at which the people that are able to work in a given population do not have the jobs that they require in the society.
Non- institutionalized population = 250 - 20 - 25 - 10 = 195 million
Labor force = 195 - 15 - 10 -20 = 150 million
Employed population = 100 + 20 = 120 million
Unemployed population = 150 - 120 = 30 million
unemployment rate = 30 / 150 x 100 = 20 percent
Hence the unemployment rate is 20 percent
