People all around the world wear brightly coloured, mis-matched socks to celebrate World Down Syndrome Day


Not only does the global community celebrate Down’s syndrome, the day allows focus on a particular issue.

This year, the global theme is “We Decide”

The theme is inspired by the United Nations Convention on the Rights of Persons with Disabilities (CRPD) which supports effective and meaningful participation as a core human right.

* It is generally accepted that both Down’s syndrome and Down syndrome can be used interchangeably. For us at the Down’s Syndrome Association, the most important thing is the use of person first terminology (e.g. “person with Down’s syndrome“, not “Down’s syndrome person“). The use of the possessive apostrophe is a recognised model that is used for a number of conditions in Britain, thus, in the UK Down’s syndrome is used more commonly, whereas in other countries the more prominent is Down syndrome.
