Unemployment figures are understated because they include

-part-time jobs at minimum wage.
-retirees on pensions.
-students in secondary schools.
-homemakers without incomes.

I have absolutely no clue what the answer to this is, can anyone please help me

This is not a well-worded question.

I think it means EMPLOYMENT figures are understated. People are considered unemployed if they are actively looking for work. However people in part-time jobs at minimum wages are not on the unemployment roles.

Employment numbers do not include the last three answers.
