According to the BHF, their analysis of the 2011 report from the British Isles Network of Congenital Anomaly Registers (Binocar), found:
- More than one in 50 babies has some sort of birth defect. This is more than double the previous estimate.
- Earlier figures suggested one in 80 babies suffers a defect at birth, including Down's Syndrome and spina bifida.
- At least 14,500 babies with birthday defects in England and Wales were alive in 2009.
- Heart defects affect at least five in 1,000 babies, making them the most common.
