The Seasonally Adjusted CPI Was up 0.368% in April

I had just posted a few days ago that it was up only 1.08% over the four months from Nov. 2022 to March 2023 (which is a 3.26% rate for 12 months).

Here are the last five monthly increases: 

Dec. 2022  0.131%
Jan. 2023  0.517%
Feb. 2023  0.370%
Mar. 2023  0.053%
Apr. 2023  0.368%

If it went up 0.368% every month for 12 months it would be 4.5%, much too high.

For more information, See US prices stay high, showing inflation pressures persist by CHRISTOPHER RUGABER, AP Economics Writer.

But this report said "consumer inflation was up 4.9% in April year over year."

That is not the right way to say it. It should say prices were up 4.9% (or were 4.9% higher in April 2023 than in April 2022). The inflation rate tells us how much prices went up.

If we had 10% inflation in Year 1 and you tell me inflation went up 4.9% in Year 2, you are telling me that inflation was 4.9% higher in Year 2 than in Year1. What number is 4.9% higher than 10%? 10.49%. That means that our inflation rate was 10.49% in Year 2. Prices went up 10.49% (and not 4.9%).

If you click on that link ("this report") it is possible that they updated it and it no longer says what I report here.
