The Bureau of Labor Statistics (BLS) made changes of
historical proportions this month by changing how the Consumer Price
Index is reported.
For the first time in history the BLS has begun reporting
the Consumer Price Index to three decimal points. Their official
statement is as follows:
"Effective with this release, index levels are now published to three decimal places. Percent changes based on these three-decimal place
indexes will continue to be published to one decimal place. "
So for January 2007 the CPI-U index is now 202.416 rather than
202.4 but their official inflation rate is still 2.1% rather than
the 2.08% that we calculate it out to.
While I applaud the higher level of accuracy on the index, I
wonder why they decided to change it? Could it be that the
index is now over 200 (indicating 100% inflation since 1982) and
they feel the need for a bit more accuracy?
The interesting thing is that we have been using that index to
calculate the inflation rate to two decimals for years but the BLS
has decided not to switch their inflation calculation to two
decimals but to switch the index to three decimals.
Or perhaps they have heard complaints like: InflationData.com is
publishing to two decimal places so why can't they? Perhaps, next
year after having three digits on the index for a year they will go
to two or three digits on the Inflation Rate, in order to keep up
with us.
In the mean time the only place to get two digit inflation rates
is at InflationData.com.
