Regression analysis
The rapid rise in the number of UK food banks since 2009 has often been used as evidence of growing hunger. Critics have argued that the rising food bank use does not prove this; it could just mean unscrupulous people are becoming more aware of food banks, and using their services not to save themselves from hunger, but to have more money free to spend on luxuries. Regression analysis published by Oxford University in 2015 found that it is largely need and not simply awareness of foodbanks that is causing the growth in usage. However the academics conducting the research agree that foodbank usage is not the best measure of hunger, saying that studies in other countries have suggested that most people suffering from food poverty don't use food banks.
