In Writing Task 1, identifying the main trends, differences, or stages is a key skill.

You need a clear overview to get a band score 7 for Task Achievement.
Task Achievement, Band score 7
The word stages refers to processes, and in questions with figures you need to think about trends and differences.
If a question has changes over time, like in this one, it's best to mention both trends and differences.
If there are no trends, like in the one about Australian poverty, I would find at least two differences to mention.
Make it easy for the examiner to give you a 7 - use the word overall, and put your overview in a separate paragraph.
The overview is the first thing the examiner looks for, so don't hide it in the introduction or at the end.
Finally, if there's a total or an average, as in the question about literacy or the one about Australian poverty, I would consider it to be the most important information, so I'd include it in the overview.
