What percentage of babies these days are born with Down syndrome?

Answer 1

Varying statistics reported by our users:

• 2 percent of the world's population has Down syndrome.

• According to Wikipedia, 0.1-0.125 % of babies who are born have Down syndrome (1 in every 800-1000 births).

• The overall incidence of Down syndrome is 1:660 newborns, thereby making it the most common genetically diverse configuration in humans.
• Research shows that 1:800-1000 people (approximately 900) are born with Down syndrome. If you compare this with the number of people on earth - 6.5 billion - then there are about 7,222,222 people with Down syndrome. This is about 0.11111110769231% of the approximate population of earth.
• According to scientific data, Down syndrome occurs in 1 out of every 750 births. The incidence, however, increases dramatically with increasing maternal age. If you look at the Related link below, you will see that, under about age 30, there is a 1:1000 chance in having a child with Down syndrome; at age 40, however, there is about a 1:100 chance. This increases to 1:10 by age 50.
• Approximately 1:800-1,000 babies are born with Down syndrome.
• The overall incidence of Down syndrome is 1:660 newborns.

Answer 2

According to the U.S. National Institutes of Health, the overall rate of incidence of Down Syndrome is 0.13% (1 in 750); but this figure is misleading since the incidence is highly related to the age of the mother. For mothers below age 30, the incidence of Down Syndrome is 0.10% (1 in 1000); but it increases dramatically after age 30. At age 41, the risk of giving birth to a Down Syndrome child is 10 times the risk at age 30. Mother's age 30 -- incidence 0.11% (1 in 900) Mother's age 35 -- incidence 0.25% (1 in 400) Mother's age 40 -- incidence 0.95% (1 in 105) Mother's age 42 -- incidence 1.7% (1 in 60) Mother's age 44 -- incidence 2.9% (1 in 35) Mother's age 46 -- incidence 5.0% (1 in 20) Mother's age 48 -- incidence 6.3% (1 in 16)

Answer 3

The incidence, however, increases dramatically with increasing maternal age. If you look at the link below, under about age 30, there is a 1:1000 chance in having a child with Down syndrome, however, at age 40, there is about a 1:100 chance. This increases to 1:10 by age 50.

80% of all children with Down syndrome are born to women under the age of 30, however, because women of this age group have children at a much higher rate than those over 30.

• Approximately 1 in 800-1,000 babies are born with Down syndrome.

• The overall incidence of Down's syndrome is 1 in 660 newborns, thereby making it the most common pattern of malformation in man.

• According to scientific data, Down syndrome occurs in 1 out of every 750 births.

Down Syndrome happens in about 1 in 800 to 1000 babies.
Approximately 1 in 800 - 1 in 1000 live births.

Answer 4

Approximately 1 in 800 people, or .12%, which is around 340,000 people.

Answer 5

Approximately 0.1% of babies are born with Down syndrome. This number may vary slightly depending on factors such as maternal age.
