Chronic hunger has affected a sizable proportion of the UK's population throughout its history. Following improved economic conditions that followed World War II, hunger became a less pressing issue. Yet since the lasting global inflation in the price of food that began in late 2006 and especially since the financial crisis of 2009, long term hunger began to return as a prominent social problem. Albeit only affecting a small minority of the UK's population. By December 2013, according to a group of doctors and academics writing in the British Medical Journal, hunger in the UK had reached the level of a "public health emergency".
