* Rates preceded by an asterisk are based on fewer than 50 births. Rates based on fewer than 20 births are considered unreliable and are not shown.

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

2

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.

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.
