Low birth weight is an important factor that influences infant survival, health and development. Babies that weigh less than 2,500 grams at birth have increased chances of experiencing health problems, slower development, and even premature death. Babies may have low birth weight if they are born prematurely or are too small for their gestational age. The percentage of low birth weight babies is a measure of infant health, and the City aims to see a downward trend over time. Data source: BC Vital Statistics.
