How has survival improved for children with Down syndrome?

One measure of the remarkable improvements in the quality of life experienced by people with Down syndrome is childhood survival rates:

  • In the 1920s, only 20% of children with Down syndrome survived to 10 years of age
  • By 2010, over 90% of children with Down syndrome (in more developed countries) were living beyond the age of 10 years
