The overall rate of DS was 1.60/1,000 live births and had minimal fluctuation throughout the 15 years. The rate of DS for Latino births was 1.69/1,000 live births, 1.67 when adjusted for maternal age, and 1.75 when corrected for prenatal diagnosis.
Is Down syndrome inherited from the mother or father?

The additional partial or full copy of the 21st chromosome which causes Down syndrome can originate from either the father or the mother.
What race has the lowest birth defects?
Compared with Caucasians, the risk of overall birth defects was lower in African–Americans (relative risk = 0.9, confidence interval 0.8–0.9) and Hispanics (relative risk = 0.9, confidence interval 0.8–0.9). The risk of overall birth defects was similar in Caucasians and Asians.
