Methodology Notes: 

    Very low birth weight (VLBW) is defined as a birth weight of less than 1,500 grams (3 lbs 4 ounces). Data are reported by states each year as part of the Maternal and Child Health Block Grant application. A national weighted average is calculated by summing the numerator and denominator information reported by each jurisdiction.

    Estimates reflect data from 59 states and jurisdictions. While the National Center for Health Statistics (NCHS) traditionally presents data for 50 States and DC, an exception was made to remain consistent with published reports of these data.

    Before 2006, states reported on the following: The percent of newborns who are screened and confirmed with condition(s) mandated by their state-sponsored newborn screening programs (e.g., phenylketonuria and hemoglobinopathies) who receive appropriate follow-up as defined by their state. After 2006, states reported on the following: The percent of screen positive newborns who received timely follow up to definitive diagnosis and clinical management for condition(s) mandated by their State-sponsored newborn screening programs.
