Down Syndrome Association of NE

According to, WDSD was first observed in 2006 in many countries around the world.

March 21 was declared World Down Syndrome Day by the United Nations General Assembly on December 19, 2011.

Why was March 21 chosen as the day for World Down Syndrome Day?

The date is to symbolize the uniqueness of the triplication (trisomy) of the 21st chromosome which causes Down Syndrome.

To bring awareness, people across the world will be wearing crazy socks.

If you wear crazy socks, WDSD wants you to post your pictures and videos on Facebook, Twitter and Instagram using the hashtags #LotsOfSocks, #WorldDownSyndromeDay and #WDSD19.

March 21 or 3-21 signifies the three copies of the 21st chromosome which is a genetic occurrence common in people with Trisomy 21, the most common form of Down syndrome

Thursday, mismatched socks also help raise awareness about Down syndrome. Organizations encourage everyone to wear brightly colored socks that signify the extra chromosome that people with Down syndrome usually carry.

Down syndrome is associated with distinct facial features, intellectual disabilities, developmental delays, and may be associated with thyroid or heart disease.

But many people with the disorder are able to lead productive lives. Most children with Down syndrome attend regular schools and 20 percent of adults are able to occupy paying jobs.

Down syndrome is diagnosed in 1 per 1,000 babies each year, resulting in approximately 200,000 new cases each year in the United States. More than 5 million people in the U.S. have Down syndrome.
