United Kingdom Retail Price Index
The Retail Prices Index (RPI) is a long-standing measure of inflation in the UK, originally designed as a compensation index to protect workers from price increases following the First World War. It covers private households but excludes the top 4% of households by income and pensioner households deriving at least 75% of their income from benefits. The RPI provides inflation estimates from 1947, with its first official consumer price inflation release published in January 1956. Until the introduction of the UK Consumer Prices Index (CPI) in 1996, the RPI and its derivatives were the UK's sole official measures of consumer price inflation.
