In calculating inflation, the Office for National Statistics puts together a basket of commonly-bought items and calculates how their prices have changed. Over time, things that have been added or deleted from the basket reveal an awful lot about our spending patterns. Between 1940 and 1949, for example, we saw condensed milk added to the list - reflecting the popularity of canned food in a pre-fridge age. Soap flakes were also added, as were a mangle, tin kettle and radio set.
The 70th anniversary of D-Day reminds us of what a lucky time we live in. When we talk of times of austerity and hardship, the last few years is small potatoes compared to the terrible deprivation and suffering of wartime.
To mark the anniversary, we look back at how our spending habits have changed in the intervening years.
