Why This Indicator Matters
Babies born with a low birth-weight have a high probability of experiencing developmental problems and short- and long-term disabilities and are at greater risk of dying within the first year of life. Smoking, poor nutrition, poverty, stress, infections and violence can increase the risk of a baby being born with a low birthweight.
