其實記了定義,點都計到。
Unemployment rate 失業率
= no. of Unemployed 失業人口/ Labor Force 勞動人口
= no. of Unemployed 失業人口 / (no. of Employed 就業人口 + no. of Unemployed 失業人口)
5% = u / (2850K + u)
u = 150K
Underemployment rate 就業不足率
= no. of Underemployed 就業不足人口 / Labor Force 勞動人口
= no. of Underemployed 就業不足人口 / (no. of Employed 就業人口 + no. of Unemployed 失業人口)
3% = under / (2850K + 150K)
under = 90K
