The bar charts provide information about the proportion of food and goods purchased from supermarkets in three European countries from 1998 to 2008.
Overall, there was an upward trend in supermarket sales across all countries, regardless of the type of products. It is also clear that at the end of the surveyed period, country A accounted for the highest percentage of food and goods bought from supermarkets.
In terms of food sales, in 1998, country B purchased nearly 25% of its food from supermarkets, taking the lead among three nations, while country A and country D stood at only 10% and around 7%, respectively. After ten years, all witnessed an upward trend, with the most significant change being recorded in country A, where the percentage of food bought in supermarkets rose to 35%, moving it from the second position to the first position. Meanwhile, country B and C increased slightly to approximately 27% and 9%.
Other goods also followed a similar pattern. In the first year, country B was at the forefront, with nearly 25% of supermarket sales, which was more than five times the amount for country A. However, by 2008, country A experienced a sharp increase, reaching almost 40%, surpassing the slower growth in country B to above 27%. While country C consistently had the lowest figures, growing from over 2% in 1998 to almost 15% in 2008.
