This is a rather misleading thing to say. In Holland they have been promoting a policy of home births very strongly for several years now. But they are seeing rates of mortality rise because of it and are currently having a bit of a policy rethink.

I'm sure there is a lower rate of complications/mortality at home births than in hospitals because whenever a significant risk of complications is identified the mother concerned is advised to give birth in hospital. So the statistics are based upon the hospitals dealing with higher risk births and home deliveries are dealing with lower risk births. Although I'm sure the risk for most mothers is very low the safest place to have your child remains in a hospital.
