NOTES: Excludes live births with unknown birthweight. Low-birthweight infants weigh less than 2,500 grams at birth, about 5.5 pounds. Very-low-birthweight infants weigh less than 1,500 grams, about 3.25 pounds.

Trend data for births to Hispanics and non-Hispanic whites and blacks are affected by expansion of the reporting area in which an item on Hispanic origin is included on the birth certificate as well as by immigration. These two factors affect the numbers of events, the composition of the Hispanic population, and maternal and infant health characteristics. The number of states in the reporting area increased from 22 in 1980 to 23 and the District of Columbia (DC) in 1983-1987, 30 and DC in 1988, 47 and DC in 1989, 48 and DC in 1990, 49 and DC in 1991-1992, and all 50 states and DC from 1993 forward. Trend data for births to Asian/Pacific Islander and Hispanic women are also affected by immigration.
