Consumer Prices Index (CPI)
The Consumer Prices Index is the main United Kingdom (UK) domestic measure of inflation for macroeconomic purposes. It measures the average change from month to month in the prices of consumer goods and services purchased in the UK, similar to the Retail Prices Index (RPI), but there are differences in coverage and methodology. Since December 2003, the inflation target for the UK is defined in terms of the CPI measure of inflation.
Retail Prices Index (RPI)
The Retail Price Index is an important domestic indicator of inflation in the United Kingdom (UK). It measures the average change from month to month in the prices of goods and services purchased in the UK.
Current prices are the actual or estimated recorded monetary value over a defined period for a group of industries or products. They show the value for each item expressed in terms of the prices of that period.
Constant prices allow researchers to examine data which has been adjusted to remove the impact of inflation. Technically, constant prices are volume measures whose values are calculated by applying prices from a specific base period to current quantities. This calculation produces a series of derived prices which facilitate comparisons across different periods.
Example: Total adspend in the first quarter of 2008 amounted to £4.28bn (approximately) at current prices while the CPI figure for the quarter was 106.167 (based on 2005 being 100). At constant prices, the figure will therefore be £4.28bn multiplied by 100 then divided by 106.167. This gives £4.03bn
Constant price figures in this report have been calculated using the CPI for all periods from 1988 onwards, and by using the RPI for all earlier periods.
