Accessibility statement

Our accessibility target for this site and how to report a barrier.

Our target

We build to WCAG 2.1 AA: contrast of at least 4.5:1 for body text, keyboard access to every interactive control, visible focus, alternative text on meaningful images, and status never communicated by colour alone.

Known limitations

Some research tables are wide and scroll horizontally on small screens. Downloadable research documents are provided as originally authored and may not meet the same standard as the site.

Reporting a barrier

If any part of this site prevents you from getting information you need, tell us through the contact page and we will provide the content in another format.
