Data are presented as percentages
a Individual BIG2 morbidities (combination of SGA and/or premature births) do not add up to ‘Any BIG2’ as newborns can have >1 BIG2 morbidity
b = Total of foetal (from 22 weeks gestational age), intrapartum, and neonatal mortality (up to 7 days after birth)
c Sum of Children 0–17 years in 2009, 2010, 2011 and 2012
