Data Lists already present information in a structured way making them accessible.
However, any special HTML present in the data can potentially cause accessibility issues that cannot be detected.
Any improvements should be made directly from each data list. Note that any accessibility improvements need to be applied to the feature itself and not the page.
Data Lists Best Practices
Use clear and easy to read data.
Avoid including HTML links or images.
If including any links, ensure that the link text is descriptive and not repetitive.
If including any images, ensure that the image includes a descriptive alt text.
