On the other hand, the CPI for wage and clerical workers rises slightly more than headline.HICP rises less by March 2024 in part because it excludes owner occupied housing costs. It also covers rural consumers as well as urban.Finally, the PCE (market based) increase is the smallest of all, less than even the conventional PCE.The range of cumulative increase through March 2024 is 0.141 to 0.179 in log terms (i.e., 14% vs. 18%).More By This Author:Grocery Prices DeclineManufacturing Over The Long Term Currency Misalignment Measured Assuming A Balanced Financial Account
