The Consumer Prices Index (CPI) is the main measure of inflation.
It is produced in line with international standards and is the measure used for the Bank of England’s 2% inflation target.
The Retail Prices Index (RPI) is no longer classified as a National Statistic as the way it is calculated does not meet international standards.
It is included here as it is well-known and is the longest running measure of inflation.
The CPI inflation rate was 1.8% in January 2019, the lowest that it has been since January 2017.
The RPI inflation rate was 2.7% in January 2019, the lowest it has been since December 2016.
