Small for gestational age (SGA) babies are those whose birth weight lies below the 10th percentile for that gestational age. Low birth weight (LBW), is sometimes used to define a baby that weighs less than 5 lb 8 oz (2500 g) regardless of gestational age.
A percentile is a number between 0 and 100 that shows how you rank compared to other students. It represents the percentage of students in a particular grade whose scores fall at or below your score. For example, a 10th-grade student whose Math percentile is 57 scored higher or equal to 57 percent of 10th-graders.
