The down syndrome percentage and miscarriages actually both vary with the age of the mother. I know that the average miscarriage rate in normal women is 1 in 8 pregnancies. High, I know, but after a heartbeat is found, the rate drops down to 1 in 1000.... per my OB

This one is hard to answer because most miscarriages happen in the first trimester, so genetic testing is not usually done before then. Although most miscarriages are caused by some sort of chromosomal abnormality. The rate of miscarriages drops significantly after the first trimester. If you are concerned about Down's Syndrome or any other chromosomal abnormality, you can get a CVS test done early in pregnancy - around 12 weeks, or you can have an amniocentesis done around 18 weeks.
I had an amnio with both pregnancies and found out with my first pregnancy that my daughter has Mosaic Down's Syndrome. She was a full-term healthy baby. My OB did a planned c-section at 40 weeks because my daughter was breech. He did not want me to go beyond 40 weeks because he informed me that babies with chromosomal abnormalities have a higher rate of being still born if pregnancy goes beyond 40 weeks.
Hope at least some of this information has helped you. Best wishes.

Here is a sight about the down syndrome and it should have the % somehwere in there.
http://patients.uptodate.com/topic.asp?file=pregnan/8003
Miscarriage is the loss of a pregnancy in the first 20 weeks. About 15 to 20 percent of known pregnancies end in miscarriage, and more than 80 percent of these losses happen before 12 weeks. This doesn't include situations in which you lose a fertilized egg before you get a positive pregnancy test. Studies have found that 30 to 50 percent of fertilized eggs are lost before a woman finds out she's pregnant, because they happen so early that she goes on to get her period about on time. If you lose a baby after 20 weeks of pregnancy, it's called a stillbirth.

miscarrages happen in an estimated 1out of 4 pregnancies, usually before 10-12 weeks. Down syndrome is rare, the likely hood varies depending on the mothers age.

I dont know the exact percentage, but I do know that women over 35 have a higher chance of a downs baby, and a women over 40 has a 1 in 12 chance of a downs baby...Also if the male is over 35 it can also be passed through the male sperm, miscarriages are common, I THINK (not 100%) but it was 33% that I heard...and most women dont even know that theyve had a miscarriage

If i found out my foetus had Down Syndrome i could abort - even after 10 weeks. i do no longer prefer to deliver a new child into the international to go through in any way. look on the international - there is not any room for people who're distinctive. existence is perplexing sufficient for those people who're 'frequent'. no1home2day - Stephen Hawking would not have cerebral palsy. He has muscular dystrophy.

For Down syndrome, the odds increase slowly but steadily with the age of the mother. They start to go up faster at the age of 40.

hi....the percentage of having a child with DS is "1" in whatever number (you don't state your age). overall 1 in 800 live births produce a child with down syndrome. though maternal age is a factor, it isn't always the case....could you be that "1'' ?...sure...(not trying to scare you) look at it this way...every time a woman gets pregnant it is a role of the dice....I have met very young women who have a child with DS and I have also met women in their 40's who gave birth to a "typical" child...basically you get what you are given. women under 35 are the largest age group giving birth to children with DS....ONLY because they are the largest group having children.
As for miscarriages....you got some really good answers so I am not going to repeat them...
