The California County Profile Reports include information on low birth weight, very low birth weight, and preterm births.
Definitions
A baby is defined as having a low birth weight if its weight is less than 2,500 grams at delivery. A baby with unknown birthweight is not considered for this analysis.
A baby is defined as having very low birth weight if its weight is less than 1,500 grams at delivery. Note that very low birth weight births are by definition also low birth weight births and counted in both birth weight measures. A baby with unknown birthweight is not considered for this analysis.
A baby is defined as preterm if its gestational age is less than or equal to 36 weeks at delivery. Note that any gestational age of less than 37 completed weeks (such as 36 weeks and 6 days) is said to have a gestational age of 36 weeks and is therefore preterm. A baby with unknown gestational age is not considered for this analysis.
