Unemployed=6097

Civilian Labour force=166818
Employment level-part-time for economic reasons.=2582
a. The civilian unemployment rate is

3.7%.

To calculate the civilian unemployment rate, we divide the number of unemployed individuals (6097) by the civilian labor force (166818) and multiply by 100.

(6097 / 166818) x 100 = 3.7%

b. The civilian unemployment rate including persons who are underemployed​ (part-time for economic​ reasons) is

4.5%.

To calculate the unemployment rate including persons who are underemployed (part-time for economic reasons), we need to add the number of individuals who are employed part-time for economic reasons (2582) to the number of unemployed individuals (6097) and then divide that sum by the civilian labor force (166818) and multiply by 100.

(6097 + 2582) / 166818 x 100 = 4.5%

To calculate the civilian unemployment rate, you need to divide the number of unemployed individuals by the civilian labor force and multiply the result by 100.

Civilian unemployment rate = (Unemployed / Civilian Labor Force) * 100

Plugging in the given values:
Civilian unemployment rate = (6097 / 166818) * 100

Calculating the value:
Civilian unemployment rate = 0.0366 * 100
Civilian unemployment rate = 3.66%

Therefore, the civilian unemployment rate is 3.66%.
