Excludes live births with unknown birthweight. Percent based on live births with known birthweight.

2

Prior to 1993, data from States lacking an Hispanic-origin item on the birth certificate were excluded. See Appendix II, Hispanic origin.

3

Percent based on live births with known smoking status of mother and known birthweight. Data from States that did not require the reporting of mother’s tobacco use during pregnancy on the birth certificate are not included. Reporting area for tobacco use increased from 43 States and the District of Columbia (DC) in 1989 to 49 States and DC in 2000–02. See Appendix II, Tobacco use.

NOTES: The race groups, white, black, American Indian or Alaska Native, and Asian or Pacific Islander, include persons of Hispanic and non-Hispanic origin. Persons of Hispanic origin may be of any race. Interpretation of trend data should take into consideration expansion of reporting areas and immigration. Data for additional years are available. See Appendix III.
