在计算你退休金增幅%时用的是根据CPI-W（这点你没说错，
）， 而不是 CPI， 那是给劳工统计局用的。
The Bureau of Labor Statistics (BLS) publishes the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) on a monthly basis. We use the CPI-W to annually adjust benefits paid to Social Security beneficiaries and Supplemental Security Income recipients.
