There are studies (Am J Epidemiol 1997; 145: 134-47) indicating that Hispanics possibly have a higher incidence at maternal age under 40. The question is as always, how reliable are those numbers.
A person who has Down syndrome is born like that; it is not something that you acquire with age.
it effects all populations :(

yes
No.

Yes, Down's Syndrome does not affect the ability to have children. Men with Down's Syndrome can father children in very rare circumstances, women with Down's Syndrome have about 50% chance of miscarriage.
Down Syndrome affects all races. Down Syndrome does not affect all races evenly its affects Mexicans more than any one else. Hispanics have larger numbers of live births suffering from Down Syndrome because they do not terminate their DS pregnancies, like other races do.
The proportion of men to women with Down syndrome is about equal.
It Could Do.
Older women who give birth have a much higher chance of having a baby with Down syndrome than do other women.
it didn't.....she just had a slower time processing things...all down syndrome people do...
You might not feel the baby as early as you would feel a child who does not have Down syndrome. However, the fetus will move at about 14 weeks. One interesting fact a lot of people do not know is that most women who are carrying a Down syndrome child never experience any morning sickness whatsoever.
No. Older women are more likely to have Down Syndrome babies. The risk is highest after age 35.
It is found in all places the same.
During meiosis, chromosomes are separated equally. When they are not separated equally - this is known as non-disjunction - the gametes end up with either an extra chromatid or no chromatid. In Down syndrome the offspring carries an extra chromatid in Chromosome 21, aka Trisomy 21.
It is acceptable to say that someone has Down Syndrome, although it may not be necessary to say it since the syndrome does have a characteristic affect on facial features which can be observed.
