Is the U.S. CPI Accurate? Flaws Could Impact Federal Payments.
The Consumer Price Index (CPI) in the U.S. estimates how prices change over time for things people buy. It's important because it affects things like wages and taxes. The U.S. Bureau of Labor Statistics (BLS) is looking at how accurate the CPI is. They found that there may be errors in the data due to sampling and bias. This means the CPI's estimate of inflation may not be completely reliable.
