Data not available.

A

Data not shown. Due to a change in reporting, data are not comparable to other years. See footnote 4.

*

Percents preceded by an asterisk are based on fewer than 50 births in the numerator.

1

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

2

Starting with 2003 data, estimates are not available for Asian or Pacific Islander subgroups during the transition from single-race to multiple-race reporting. See Appendix II, Race, Birth File.

3

Prior to 1993, data from states lacking an Hispanic-origin item on the birth certificate were excluded. See Appendix II, Hispanic origin. Data for non-Hispanic white and non-Hispanic black women for years prior to 1989 are not nationally representative and are provided for comparison with Hispanic data.

4

Percent based on live births with known smoking status of mother and known birthweight. Only reporting areas that have adopted the 2003 revision of the U.S. Standard Certificate of Live Birth are shown because maternal tobacco use data based on the 2003 revision are not comparable with data based on the 1989 or earlier revisions to the U.S. Standard Certificate of Live Birth. In addition, California did not require reporting of tobacco use during pregnancy. See Appendix II, Cigarette smoking. Data for 2004 and 2005 include the 7 reporting areas (states) that adopted the 2003 revision of the U.S. Standard Certificate of Live Birth in 2004. For data for reporting areas that use the 1989 revision of the U.S. Standard Certificate of Live Birth, see: Births: Final data for 2005, available from http://www​.cdc.gov/nchs/births.htm.

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. Starting with 2003 data, some states reported multiple-race data. The multiple-race data for these states were bridged to the single-race categories of the 1977 Office of Management and Budget standards for comparability with other states. See Appendix II, Race. Interpretation of trend data should take into consideration expansion of reporting areas and immigration. Data for additional years are available. See Appendix III.
