Consumer Price Index For Urban Wage Earners and Clerical Workers - CPI-W
  
Nothing is more fun than reading long dictionary entries. Since the name of this term is so long, let’s just get right to it.
The CPI-W is a monthly figure computed by the Department of Labor that measures changes in prices paid by clerical employees, sales employees, craft workers, service workers, and other urban laborers.
The Social Security office uses this metric to adjust annual payments to Social Security beneficiaries. The Bureau of Labor Statistics computes the average change for a basket of different products and services.
