### Why is this important?
Duplicating a table’s caption and its summary description is repetitive and slows productivity for Assistive Technology users. If used, the summary should provide complementary information not already available in the caption.
<!-- This is where the code snippet is injected -->
<div id="locSnippet"></div>
### What to do
* If the table caption describes the table purpose and structure fully, remove the summary;
* **Or**, if information beyond the caption is needed, write a summary that describes the table structure without duplicating information in the caption. The summary should be referenced with an `aria-describedby` attribute. The `summary` attribute is obsolete in HTML5.
For example:
```
<p id="table1_summary">
The age demographics of each North American country includes age structures from 0-14 years, 15-64 years, and 65 years and older.
</p>
<table aria-describedby="table1_summary">
<caption>Age Demographics of North American Countries</caption>
. . .
</table>
```
