Yes, the risk of having a child with Down syndrome increases with maternal age, especially after the age of 35. This is because older eggs are more likely to have chromosomal abnormalities, such as an extra copy of chromosome 21 which causes Down syndrome.

What percentage of babies these days are born with Down syndrome?
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.
Percentage of people that are affected by downsyndrome?
* Down syndrome, caused by trisomy of the 21st chromosome, overall is seen in about 1 in 750 live births. 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.
What is the frequency of Down syndrome compared to other genetic diseases?
Down syndrome is one of the most common genetic disorders, occurring in approximately 1 in 700 live births. However, other genetic diseases such as cystic fibrosis and sickle cell anemia have different frequencies depending on the population and genetic factors involved.
How many people in the us have metabolic syndrome?

What are the causes and risk factors of down syndrome?
The causes and risks factors are maternal age. Have babies at early age as the risks increases with age. About 1:2000 live births in age 20 to 1:300 at age 35 to 1:40 at age 45.
What maternal characteristic is associated with having a down syndrome baby?
The only maternal characteristic to show a strong enough association to imply any causation is advanced maternal age, some sources reporting >35 years and some up to >45 years.
If a woman had a distant relative or an ancestor with Down syndrome would it increase the chances that this woman would bear a child with Down syndrome?
I would say no. Down Syndrome is caused by an extra chromosome (extra pair of chromosome 21). If anyone has three chromosomes 21, they have Down; you can't have "latent Down" and transmit it to your children. What increases the risk for Down most is older parental age, especially maternal (>35, and especially >40). Most standard prenatal screenings now can detect Down in the fetus very early on.
What are the odds at various ages of giving birth to a baby with Down syndrome?
Maternal age influences the odds of conceiving a baby with Down syndrome.The incidence of Down syndrome in a woman under 30 is approximately 1:1,000, according to the National Institutes for Health (NIH). This increases to approximately 1:400 by the age of 35, and to 1:12 by age 49.Some breakdown figures from our contributorsAt the maternal age of 20-24, the probability is 1:1562At 37, the odds of having a child with Down syndrome are about 1:170 (according to my doctor from a top-ranked hospital as of Dec 2008).At age 35-39, the probability is 1:214Above age 45, the probability is 1:19.
What are the possible vaccinations for down syndrome?
There are no vaccinations available. The causes and risks factors are maternal age. Have babies at early age as the risks increases with age. About 1:2000 live births in age 20 to 1:300 at age 35 to 1:40 at age 45.
What is the most common chromosomal abnormality seen in live born babies what is the prevalence of this disorder what is the relationship between maternal age and the risk of having a baby with this?
Down Syndrome-the rest is on wikipedia
In which age bracket do people mostly get Down syndrome?
Down syndrome is something a baby has at birth. It is not a condition that you can "get" at a later age.
What age group is most affected by Down syndrome?
No age group is affected; Down syndrome is a chromosome condition that is with you at birth.
What week of development does down syndrome occur?
At age 30, for example, a woman has about a 1 in 900 chance of conceiving a child with Down Syndrome. Those odds increase to about 1 in 350 by age 35. By 40 the risk rises to about 1 in 100.It occurs by going through fermentation and supplies alcohol in the brain resulting in down syndrome.
