The chart below compares the regularity of fast food consumption among people in the USA from 2003 to 2013. Overall, it is clear that people often ate fast food once a week or once or twice a month over the course of 2003 and 2013, with eating fast food once or twice a month in 2013 becoming the highest proportion. There was a notable decrease in the daily, several times a week, once a week, and never categories, while once or twice a month and a few times a year saw an increase.
In 2003, the ratio of people in the USA who ate at fast food restaurants once a week reached a peak of around 33%, followed by a slight escalation to nearly 35% in 2006 before tapering off to lower than 30% in 2013. In comparison to the once or twice a month category, the percentage persisted in a decline between 2003 and 2006, with the figure remaining at precisely 30% and falling by 5% before hitting a high point of around 36% at the end of the period.
The figure for people in the USA who consumed convenience food several times a week exhibited a pronounced fluctuation, leveling off from 20% to around 15% in 2013. In contrast, approximately 14% of people in the USA ate a few times a year, with a slight rise to 15% and then remained steady in the final stages. The share of daily fast food consumption saw a similar change to the share of those who never consumed fast food, starting at roughly 5% during the initial phase before plunging to a low of about 4% at the end of the period.
