The first bar chart compares the percentage growth in prices of several consumer products between 2007 and 2014, while the second chart illustrates how the purchases of the same items changed over the shorter period from 2007 to 2012.
Overall, the two charts reveal an inverse relationship: products that experienced sharp increases in price generally recorded falling sales, whereas those with more moderate or negligible price rises tended to see demand increase.
Vegetables showed the smallest price rise at 25%, around 15% lower than fish, which topped the chart at 37%. Fruit ranked second at 34%, while flour stood in between, with a 31% increase. Cheese and soft drinks were almost identical, though the former was slightly higher at 29% compared to 28%.
Flour recorded by far the largest growth, surging from 0% to nearly 90%. By contrast, both fruit and fish dropped by around 19%, while vegetables and cheese fell slightly, by 6% and 4% respectively. Soft drinks saw the smallest decline, at just 3% among low-income households.
