I've been seeing some mischaracterizations of the recent inflation situation in the media, so here is a summary table followed by the graphs.

I annualize them all to be easy to compare to each other, and to compare to the FED's 2% goal. I use the actual index values rather than the one-digit changes that are commonly reported in the media. Links to the data are with the graphs.

ALL the numbers are the seasonally adjusted ones

The "1 month" number is the change from March to April expressed as an annualized number. (Exception: The PCE is from February to March -- they don't update their number for April until late in May)

The "3 month" number is the growth over the last 3 months (and then annualized). It is calculated based on the change in the index number between the latest one and the one 3 months previous. e.g. if the latest index value is 304 and the one 3 months previous is 300, then the 3 month increase is 1.333333%
. . . (304/300 = 1.01333333 => [subtract 1 and multiply by 100%] => 1.333333%)
Annualized, it is 5.4%
. . . (1.01333333^4 = 1.0544095 => [subtract 1 and multiply by 100%] => 5.44095% => 5.4%).
. . . Most people just multiply the 3 month increase by 4 to annualize it: 1.333333%*4 = 5.333333% => 5.3% which isn''t technically correct (it leaves out compounding) but it is close for small percentage changes.

"Regular" is the "headline" number that has "everything"

"Core" is the regular with food and energy removed (The Fed prefers this as a basis for projecting FUTURE inflation)

Finally, the main summary table
All are seasonally adjusted and annualized
PCE-Personal Consumption Expenditures Price Index (Fed's favorite inflation measure)
CPI-Consumer Price Index (retail)
PPI-Producer Price Index (Wholesale prices)
Links to the data are with the graphs below



Average real (i.e. inflation-adjusted) hourly earnings are up over the past 2 years and are above the pre-pandemic level:
. . . # Real average hourly earnings of production and non-supervisory workers: https://data.bls.gov/timeseries/CES0500000032
. . . # Real average hourly earnings of private sector workers: https://data.bls.gov/timeseries/CES0500000013

And now the graphs, in the following order:

* Core PCE and Regular PCE (Core PCE is the Fed's favorite for projecting FUTURE inflation)

* Core CPI and Regular CPI

* Wholesale inflation - Core PPI and Regular PPI

CORE PCE through *March* that came out 4/26/24
CORE PCE (seasonally adjusted): https://fred.stlouisfed.org/series/PCEPILFE
BEA.gov News release: https://www.bea.gov/ and click on "Personal Income and Outlays" or "Personal Income"

This is the one that the Fed weighs most heavily. The Fed weigh the PCE more heavily than the CPI. And in both cases, they weigh the CORE measures higher than the regular headline measures for projecting FUTURE inflation



Regular PCE through *March* that came out 4/26/24

WHOLESALE INFLATION (PPI - the Producer Price Index)

https://www.bls.gov/news.release/ppi.nr0.htm

As for which core PPI measure, since the BLS highlights the one below in its reporting (as opposed to the one without food and energy), then I guess I should do likewise.

CORE PPI (excluding food, energy, trade services) through April that came out 5/14/24:
