Your basket: ins and outs

The rate of inflation in the UK is measured using the Consumer Prices Index (CPI). This is made up of a basket of goods and the ONS updates this ‘basket’ each year to ensure it is representative of what the average UK household buys. The basket contains 703 items, with 110,000 individual prices collected each month.

In past years, items such as lip gloss have been added to the basket of goods, together with tablet computers and teenage fiction. In the recent update by the ONS, e-cigarettes have been added, together with specialist ‘craft’ beers and music streaming. On the other hand, other items have been removed, as the world changes. For example, during the recession, champagne was removed as an item that the representative household was no longer buying. In other cases, items are removed as they become outdated or obsolete with technology changing. This is the case with satellite navigation systems. As people turn to using their smartphones to navigate their way from A to B, satellite navigation systems are no longer seen as an item bought by the representative household.

The UK inflation rate is at an all-time low of 0.3% and there have been concerns that it may become negative, meaning we enter the world of deflation. However, if this does occur, many suggest that it is not bad deflation, as it is being driven by the extremely low oil prices. No matter what the inflation rate, the ONS will always continue to update the basket of goods that calculates inflation. It is therefore essential that these changes are made each year, as consumer buying habits do fluctuate considerably, as income changes, technology changes and general tastes change. The following articles consider what’s in and what’s out.
