Why March 21?

The 21st day of the third month (21st March) was chosen as “World Down Syndrome Day” to signify the uniqueness of the triplication (trisomy) of the 21st chromosome which causes Down syndrome.

About Down Syndrome: 

Down syndrome (or Trisomy 21) is a condition in which a person has an extra chromosome.  Down syndrome usually causes varying degrees of intellectual and physical disability and associated medical issues.

  • Chromosomes are “packages” of genes in the body. They determine how a baby’s body forms and functions as it grows.

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.


As a part of the WDSD 2023, the Down Syndrome International network hosted the 12th World Down Syndrome Day Conference (WDSDC) at the United Nations headquarters in New York, United States of America(USA).
