It's interesting to note that the test isn't conclusive, and it's possible to get a false positive. In addition, there's a variant of Down's that is referred to as a mosaic form, where the trisomy 21 occurs in just one or more cell lines. It's possible that any one of the members here has a mosaic form, and is completely unaware of the fact.

How many foetuses have been aborted, where there might be no significant impact on the child, we do not know.
