Talk:United States Chained Consumer Price Index

Some issues resolved, but needs some expert input

The article does does not presently define the term that the page purports to explain. Please, someone, help make it understandable and relevant! — Preceding unsigned comment added by 173.165.56.246 (talk) 03:59, 8 March 2013 (UTC)

I added a link from the main CPI article to remove the orphan status, added wikilinks within the article, and worked on the formatting, but I did not change any content. I am not an expert on the subject matter, but it does appear that there are some possible bias issues that should be addressed by someone with more relevant subject matter knowledge.

I'm not an expert, but I took a shot at at least defining how it's calculated in plain English. I doubt I succeeded, but it's a start. --j⚛e decker^talk 04:04, 14 March 2013 (UTC)

Inaccurate citation for CBPP allegedly supporting chained CPI

Since this is a currently controversial topic and I haven't edited wikipedia recently, I want to post this here for discussion rather than immediately changing it, but it needs to be fixed. The second paragraph starts: "Proponents of the chained CPI include the Washington Post Editorial Board[2] the Committee for a Responsible Federal Budget,[3] the Center for Budget and Policy Priorities,[4] and the Heritage Foundation [5] and ..." Well I read reference [4] which currently points to a Heritage Foundation blog and I could not find any citation there supporting the statement that Center for Budget and Policy Priorities supports chained cpi. They very well might, but if so it needs a correct citation. MoxRox (talk) 16:43, 10 April 2013 (UTC)

Methodology

I deleted the separate section on "Methodology" primarily because the BLS references I read conflicted with the claims in this section, which referenced a macroeconomics text (Feigenbaum, Susan; Hafer, R.W. (2011-09-30). Principles of Macroeconomics: The Way We Live. Macmillan. pp. 184–. ISBN 9781429220200. Retrieved 14 March 2013.). The Wikipedia article on United States Consumer Price Index includes more discussion of methodology with more links.

Secondarily, I added comments on methodology earlier in the article.

I am not an economist, but I believe all the changes I made were solidly grounded in the references I cited. If anyone has problems with any of the current text, please cite sources so a competent researcher can verify the claims. Thanks, DavidMCEddy (talk) 21:24, 13 April 2013 (UTC)

IRS inflation adjustments using C-CPI not covered

I don't think this article adequately reflects the IRS' dependence on the C-CPI for its annual inflation adjustments since 2017, under the bill that enabled an upward transfer of wealth, i.e. the one prior to 2025's BBB. according to <https://taxfoundation.org/data/all/federal/2025-tax-brackets/>, "The IRS used to use the Consumer Price Index (CPI) to calculate the past year’s inflation. However, with the Tax Cuts and Jobs Act of 2017, the IRS will now use the Chained Consumer Price Index (C-CPI) to adjust income thresholds, deduction amounts, and credit values accordingly." Posting this topic here as a point of information. Won't add via a sourced edit until editors with more subject knowledge weigh in.Dano67 (talk) 20:53, 28 February 2026 (UTC)
