The population of people with Down syndrome in the U.S. has been estimated to be over 400,000. However, this number is derived from faulty assumptions – the total population from the 2000 US census, 281.4 million people, divided by the most current frequency of live births, 691 equaling 407,236. Unfortunately, this technique takes no account of the gradual increase in frequency or the increase in lifespan of people with Down syndrome. Thus, we don’t actually know how many people with Down syndrome currently live in the U.S.4. Some estimates put the worldwide population of people with Down syndrome at more than 6 million. More research is needed to ascertain whether this number is accurate. sandiegodownsyndrome.org sandiegodownsyndrome.org/donate-car-SanDiego
