The chart below shows how frequently people in the USA ate in fast food restaurants between 2003 and 2013.
This essay question is from Cambridge IELTS 12 Test 7 Writing Task 1.
The bar chart displays the frequency with which people in the USA ate in fast-food outlets between 2003 and 2013.
Overall, in all three years, the two largest groups were those eating in fast-food restaurants once a week and those eating there once or twice a month. Those eating there daily and those never eating there, in comparison, accounted for the smallest proportions.
The majority of people ate in fast-food outlets weekly in both 2003 and 2006, at about 31% and 33% respectively. However, the percentage dropped to 27 in 2013. The proportion of those in the “once or twice a month” category first fell from 30% to 25% between 2003 and 2006. It then went up significantly to 33% in 2013, making these people the largest group that year.
The proportion of those eating in fast-food restaurants several times a week varied between 15% and 20%, while the proportion eating there a few times a year showed an increase from 13% to 15% over the period. By contrast, in none of the three years were more than 5% of people ever in either of the “every day” or “never” categories.
How to Vary Your Language
Example The proportion of people who ate in fast-food restaurants daily was never as high as 5% in any of the three years.
However, there is no justification to use “on a weekly basis”. It’s unnecessary verbiage.
Once a Week
Please don’t change it to “weekly”. “Weekly” is too imprecise for the chart because it can mean once a week or several times a week.
Proportion of People
When writing your essay, you may say something like “the proportion of people who…increased.” You can use the constructions below to avoid repeating “proportion of people” too many times.

How to Group Data
I don’t think the most obvious features of the chart are which categories increased in 2013 and which decreased. That’s why I didn’t group them by trends. Instead, I grouped them by which ones have big figures and which ones have small figures.
