The Office of National Statistics has measured what the average UK household is buying this year.
Every year it collects prices of over 700 items and the information is used to work out the rate of inflation.
The basket changes to reflect our spending habits: in the 1950s loose tea was a popular household buy.
Items we are buying more of are added to the basket; this year the basket included tablet computers, teenage fiction, soft cheese and pineapple.
Those we are buying less of are taken out; this year we bought less camera film, casserole dishes and boiled sweets.
