Model Answer

The bar chart depicts the frequency with which Americans ate at fast food restaurants during a 10-year period (2003-2013) using three data points: 2003, 2006, and 2013.

In 2006, there was an increase in the percentage of people eating at fast food restaurants several times a week. However, by 2013, fewer people were doing so than in 2003; an overall decline over the 10-year period.

In contrast, the percentage of people who ate at fast food restaurants once or twice a month dropped from 2003 to 2006 but then increased dramatically by 2013; showing considerable growth over the 2006 level.

Notably, the only frequency period showing growth, in terms of percentage of people, in recent years (2006-2013) is that of once or twice a month; in all other cases, the percentage of people either remained stable or decreased.

Overall, on average, approximately 60% of the population ate at a fast food establishment either once a week or once or twice a month.
