How pay has fallen behind inflationHow pay has fallen behind inflation
UK inflation stood at 2.7% in December 2012, the Office for National Statistics (ONS) revealed today - unchanged from November. UK inflation stood at 2.7% in January 2013, the Office for National Statistics (ONS) revealed today - unchanged unchanged for the fourth month in a row.
What has kept inflation high? The ONS blames the rising cost of food and home energy bills. Josephine Moulds writes today: What has kept inflation high? Larry Elliot writes today:
Five of the big six energy companies introduced price rises in December, hitting some 25m households. That was partially offset by a decline in petrol prices, which fell by 2.8p a litre between November and December. Britain's annual inflation rate was pegged at 2.7% for the fourth successive month in January, as cheaper clothes and shoes in the new year sales helped offset dearer alcohol and tobacco.
The Office for National Statistics said it was the first time since recent records began in 1996 that inflation as measured by the consumer prices index had remained at the same level for four months.
Living standards have been falling consistently over the past twelve months, as inflation has run well above the rate of pay increases, which the latest labour market data showed averaging at less than 2%.Living standards have been falling consistently over the past twelve months, as inflation has run well above the rate of pay increases, which the latest labour market data showed averaging at less than 2%.
Measured on the retail prices index (RPI), which includes mortgage interest payments, the inflation rate was 3.1% in December, up from 3% in November. Measured on the retail prices index (RPI), which includes mortgage interest payments, the inflation rate was 3.3% in January up from 3.1% in December 2012.
The ONS publish two measures of inflation. The consumer price index (CPI) measure of inflation which we have quoted above. In September 2011, when the CPI stood at 5.2%, it had never been higher in recorded history.The ONS publish two measures of inflation.

The second measure is the retail price index (RPI) which stands at 3.1% for December, up from from 3% in November. We have also added in pay data - and you can see how inflation has been racing ahead of average earnings. Even with the falls in previous months, people's wages are not increasing as fast as the cost of living. The second measure is the retail price index (RPI) which stands at 3.3% for January.

There are some important differences between the two ways the ONS measures inflation. The government prefers the consumer price index, which also includes services, housing, electricity, food, and transportation, but the retail price index covers more items. The RPI includes housing costs and is used for many pay negotiations and used to be used for pension payments. We've included both here - just click on the links on the spreadsheet.
