title: The validity of information on "race" and "Hispanic ethnicity" in California birth certificate data.
abstract: OBJECTIVE
  To evaluate the validity of racial/ethnic information in California birth certificate data.
  
  
  METHODS
  Computerized birth certificate data and postpartum interviews with California mothers.
  
  
  METHODS
  Birth certificates were matched with face-to-face structured postpartum interviews with 7,428 mothers to compare racial/ethnic information between the two data sources. Interviews were conducted in Spanish or English during delivery stays at 16 California hospitals, 1994-1995.
  
  
  RESULTS
  The sensitivity of racial/ethnic classification in birth certificate data was very high (94 percent to 99 percent) for African Americans, Asians/Pacific Islanders, Europeans/Middle Easterners, and Latinas (Hispanics). For Native Americans, however, the sensitivity was only 54 percent. The positive predictive value of birth certificate classification of race/ethnicity was high for all racial/ethnic groups (96 percent to 97 percent).
  
  
  CONCLUSIONS
  Despite limited training of birth clerks, the maternal racial/ethnic information in California birth certificate data appears to be a valid measure of self-identified race and Hispanic ethnicity for groups other than Native Americans.
