World Down Syndrome Day 2021

Overview

World Down Syndrome Day (WDSD) is observed on 21 March each year. WDSD is a global awareness day which has been officially observed by the United Nations since 2012. On 19 December 2011, the United Nations General Assembly declared 21 March as World Down Syndrome Day (A/RES/66/149). The date for WDSD being the 21st day of the 3rd month, was selected to signify the uniqueness of the triplication (trisomy) of the 21st chromosome which causes Down syndrome.

Objectives

• To show how effective and meaningful participation of persons with Down syndrome can be achieved via accessible information and communication, good support and inclusive consultation;
• To empower persons with Down syndrome, those supporting them and their representative organisations, to advocate for effective and meaningful participation;
• To reach out to key stakeholders, including education, health and social care professionals, employers, community and public bodies, the wider disability movement, media and the wider community to disseminate this message and bring about change.

Down syndrome

Down syndrome (or Trisomy 21) is a naturally occurring chromosomal arrangement that has always been a part of the human condition, being universally present across racial, gender or socioeconomic lines in approximately 1 in 800 live births, although there is considerable variation worldwide. Down syndrome usually causes varying degrees of intellectual and physical disability and associated medical issues.

Facts

• The estimated incidence of Down syndrome is between 1 in 1,000 to 1 in 1,100 live births worldwide. Each year, approximately 3,000 to 5,000 children are born with this chromosome disorder.
