What is World Down Syndrome Day (WDSD)

March 21st is a global day of celebration and awareness that has been observed by the United Nations since 2012. It’s purpose is to educate the world on what Down syndrome is and how individuals with Down syndrome need to be valued in their communities. The date for WDSD symbolizes the 21st day of the 3rd month, which was selected to signify the triplication (trisomy) of the 21st chromosome which is Down syndrome. 

About Down Syndrome

Down syndrome is one of the most common genetic variations and occurs in approximately one in every 700 live births in the United States. It is a naturally occurring chromosomal arrangement, being present across racial, gender or socioeconomic lines. According to the CDC, there are three types of Down syndrome: Trisomy 21, Translocation Down syndrome, and Mosaic Down syndrome. 

Get Involved

WDSD is a great opportunity to spread awareness!  Each year, in our little corner of the world, we are proud to celebrate our community and to do our part to spread awareness, acceptance and inclusion. 

Stronger Together – One Stride at a time!

This past year has tested our community in more ways than one.  Through numerous trials and challenges, we have demonstrated our resilience, banding together while apart to continue advocating for the needs and rights of individuals with Down syndrome throughout the lifespan.  The coronavirus pandemic has shed the light on our individual and collective strength. With eyes set on the future, we are indeed together in pursuit of our shared mission. Help us raise awareness and funds by participating in a run, walk, bike ride or hike that you can do from anywhere. All donations will go directly to the Massachusetts Down Syndrome Congress to support individuals with Down syndrome and their families.
