The given bar chart compares how often junk food consumption occurs in the USA in three different years: 2003, 2006, and 2013.
Overall, it is noticeable that most people eat fast food weekly or a few times per month. Besides, the figures generally follow a similar trend over the ten-year period.
According to the chart, over a quarter of the total population in the USA eat fast food once a week or monthly. While the percentages for 2003 and 2006 are higher for the weekly group at 31% and 33% respectively, people preferred to consume fast food less frequently in 2013, with its peak at 33% for the monthly group.
Regarding the remaining figures, they are all under 20% for the given three years. There are only slight differences between the proportion of individuals who eat junk food daily or never; the highest is 5% in 2003 for the latter category. However, the figures for 2006 and 2013 were the same for two groups; approximately 3% of the population ate fast food every day and exactly 15% did this quite a few times per year in both years.
