The 1925 inflation rate was 0.00%. The inflation rate in 1926 was -0.54%. The 1926 inflation rate is lower compared to the average inflation rate of 4.51% per year between 1926 and 2019.

Inflation rate is calculated by change in the composite price index (CPI). The CPI in 1926 was 18.50. It was 18.60 in the previous year, 1925. The difference in CPI between the years is used by the Office for National Statistics to officially determine inflation. Because the 1926 CPI is less than 1925 CPI, negative inflation (also known as deflation) has occurred.

Data Source & Citation

Raw data for these calculations comes from the composite price index published by the UK Office for National Statistics (ONS). A composite index is created by combining price data from several different published sources, both official and unofficial. The Consumer Price Index, normally used to compute inflation, has only been tracked since 1988. All inflation calculations after 1988 use the Office for National Statistics' Consumer Price Index, except for 2017, which is based on The Bank of England's forecast.
