CPI is not used for benefits calculation. Only OPM is used and OPM formula is 3x of USDA low-cost food plan. Nothing about rent, healthcare, age of the people etc. If they use CPI, it would be a much better scheme. SPM uses more variables, but it is not the official definition for poverty measurements.
