a The 1977 Office of Management and Budget (OMB) standards for data on race and ethnicity were used to classify persons into one of the following four racial groups: White, Black, American Indian or Alaskan Native, or Asian or Pacific Islander. The following states reported multiple-race data in 2003, following the revised 1997 OMB standards: CT, HI, OH (for December only), PA, UT, and WA. In 2004, the following states began to report multiple-race data: FL, ID, KY, MI, MN, NH, NY State (excluding New York City), SC, and TN. Multiple-race data were reported by 19 states in 2005: FL, ID, KS, KY, NE, NH, NY State (excluding New York City), PA, SC, TN, TX, VT (beginning July 1), WA, CA, HI, MI (for births at selected facilities only), MN, OH, and UT. In 2006, 23 states reported multiple-race data: CA, DE, FL, ID, KS, KY, NE, NH, NY State (excluding New York City), ND, OH, PA, SC, SD, TN, TX, VT, WA, WY, HI, MI (for births at selected facilities only), MN, and UT. In 2007, 27 states reported multiple-race data: CA, CO, DE, FL, GA (partial year only), ID, IN, IA, KS, KY, MI (for births at most facilities), NE, NH, NY State (excluding New York City), ND, OH, PA, SC, SD, TN, TX, VT, WA, WY, HI, MN, and UT. In 2008, 30 states reported multiple-race data: CA, CO, DE, FL, GA, HI, ID, IN, IA, KS, KY, MI, MN, MT, NE, NH, NM, NY, ND, OH, OR, PA, SC, SD, TN, TX, UT, VT, WA, and WY. In 2009, 33 states and the District of Columbia reported multiple-race data: CA, CO, DE, FL, GA, HI, ID, IN, IA, KS, KY, MI, MN, MT, NE, NH, NM, NV, NY, ND, OH, OK, OR, PA, RI, SC, SD, TN, TX, UT, VT, WA, and WY. In 2010, 38 states and the District of Columbia reported multiple-race data: CA, CO, DE, FL, GA, HI, ID, IL, IN, IA, KS, KY, LA (after January 1), MD, MI, MN, MO, MT, NE, NH, NM, NV, NY, NC (after January 1), ND, OH, OK, OR, PA, RI, SC, SD, TN, TX, UT, VT, WA, and WY. In 2011, 40 states and the District of Columbia reported multiple-race data: CA, CO, DE, FL, GA, HI, ID, IL, IN, IA, KS, KY, LA, MD, MA (in February-March), MI, MN, MO, MT, NE, NV, NH, NM, NY, NC, ND, OH, OK, OR, PA, RI, SC, SD, TN, TX, UT, VT, WA, WI, and WY. The multiple-race data for these states were bridged to the single-race categories of the 1977 OMB standards for comparability with other states. In addition, note that data on race and Hispanic origin are collected and reported separately.
NOTE: Excludes live births with unknown birthweight. Trend data for births to Hispanic and to White, non-Hispanic and Black, non-Hispanic women are affected by expansion of the reporting area in which an item on Hispanic origin is included on the birth certificate. The number of states in the reporting area increased from 22 states in 1980 to 23 states and the District of Columbia (DC) in 1983–1987, 30 states and DC in 1988, 47 states and DC in 1989, 48 states and DC in 1990, 49 states and DC in 1991–92, and all 50 states and DC from 1993 onward. Trend data for births to Asian or Pacific Islander and Hispanic women are also affected by immigration. Beginning in 2003, data are no longer available for Asian or Pacific Islander subgroups.
