Statistical survey about death of young children in England

Does a statistical survey about death of young children in England demonstrate a problem in their medical treatment?

This result suggests that consanguinity is leading to the birth of children with doubled harmful recessive genes — which is what we expect it to do, more or less. But in order to be sure of this conclusion, we need to know what fraction of children born have consanguineous parents. If that too is 7%, it would imply that those children face no greater danger of early death than other children. If that is less than 7%, it would imply that they do face a greater danger of early death.

If the risk is indeed higher for children of consanguineous parents, the next crucial question is how big a problem this is. What fraction of children of consanguineous couples in England die young? What fraction of children born in England die young? If that is a very small fraction, this problem affects few children.

Another question remains: supposing that this problem is substantial, how big is it compared with the other threats to the health of children in England?

And another one is, supposing that this problem causes a big danger to the children of consanguineous parents in England, is there an effective way to reduce that danger?
