The figure above is a bar chart showing that infants who do not survive the first year of life are more likely to be born at earlier gestational ages. In 2014, 66% of infants who survived to age 1 year were delivered at full term or later (≥39 completed weeks) compared with 16% of infants who died before reaching age 1 year. Fifty-eight percent of infants who died before age 1 year were delivered at <32 weeks gestation compared with only 1% of infants who survived to age 1 year.
