What index is used to calculate COLA adjustments?

The Cost-of-Living Adjustment (COLA) for Social Security benefits is calculated using the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W). This index measures the average change over time in the prices paid by urban consumers for a market basket of consumer goods and services. The CPI-W is specifically designed to reflect the spending patterns of urban wage earners and clerical workers, making it particularly relevant for determining adjustments to Social Security benefits, as it captures inflation trends that affect a significant portion of the population receiving these benefits.

While other indices such as the CPI-U (Consumer Price Index for All Urban Consumers) and CPI-E (Consumer Price Index for the Elderly) may provide insights into broader consumer prices or specific demographic spending patterns, the CPI-W is the index that the Social Security Administration has chosen to tie COLA adjustments to, ensuring that benefits keep pace with price increases as experienced by the core demographic of Social Security beneficiaries.

The CPI-R (Consumer Price Index for Rural Areas) is less relevant in this context, as it focuses on price changes in less populated areas and does not reflect the typical expenses faced by most Social Security recipients who are predominantly urban wage earners.
