Birthweight of babies born to Indigenous mothers provides an overview of the birthweight of babies born to Indigenous mothers, including recent trends and information on factors associated with birthweight variation. According to data from the National Perinatal Data Collection, 3.9% of all births in 2011 were to Indigenous mothers. Excluding multiple births, 11.2% of liveborn singleton babies born to Indigenous mothers were of low birthweight—2.5 times the rate for non-Indigenous mothers (4.6%). Between 2000 and 2011, there was a statistically significant decline in the low birthweight rate among Indigenous mothers, and the gap in birthweight between babies born to Indigenous and non-Indigenous mothers declined significantly over this period.
