both annualized, calculated using actual index values
Standard template words coming later when I update its table

It's not comforting to me at all that the last 3 months have averaged 3.6% (annualized) for both the CPI and the core CPI. The 3 month average is my favorite gauge of RECENT inflation. The 1 month number can be dismissed as a "one off", while the 12 month average (year-over-year) has too much old data in it to be considered a good measure of RECENT inflation -- half the months are March 2025 or older, for example. Four of the months are Biden-era months.


Regular CPI


Core CPI -- Regular CPI less food and energy


From the OP, 12 month aka year-over-year
