as weight is easier to determine than gestational age, the world health organization tracks rates of low birth weight (< 2,500 grams), which occurred in 16.5 percent of births in less developed regions in 2000. it is estimated that one third of these low birth weight deliveries are due to preterm delivery. weight generally correlates to gestational age, however, infants may be underweight for other reasons than a preterm delivery. neonates of low birth weight (lbw) have a birth weight of less than 2500 g (5 lb 8 oz) and are mostly but not exclusively preterm babies as they also include "small for gestational age" (sga) babies. weight-based classification further recognizes "very low birth weight" (vlbw) which is less than 1,500 g, and "extremely low birth weight" (elbw) which is less than 1,000 g. almost all neonates in these latter two groups are born preterm.
