The given bar chart compares how often people in the USA ate at fast food restaurants in three different years: 2003, 2006, and 2013.
Overall, the most common habits were eating fast food once a week or once or twice a month. Daily consumption remained very low throughout the period, while the percentage of people who never ate fast food also stayed small.
In 2003 and 2006, the largest group of people ate at fast food restaurants once a week, at about 31% and 33% respectively. However, by 2013 this figure dropped slightly to around 28%. The second most popular frequency in 2003 was eating once or twice a month, at 30%. This number fell a little in 2006 to 25%, but then increased significantly to about 33% in 2013, making it the most common habit in that year.
Less frequent visits showed smaller changes. Around 17-20% of people ate fast food several times a week, with a peak in 2006. Eating fast food a few times a year remained stable at about 13-15% across all years. In contrast, daily eating was very uncommon, staying below 5% in every year. Similarly, only a very small proportion of people – around 4-5% – reported never eating fast food.
