Abstract

OBJECTIVES: We compared data on race as reported by the mother on North Carolina birth certificates with data on race in officially reported statistics. We also determined to what extent differences in the classification of race affect measures of racial disparity in maternal and child health indicators. METHODS: We examined how data on race are collected, coded, and tabulated in North Carolina via live birth certificates, death certificates, the Behavioral Risk Factor Surveillance System (BRFSS) telephone survey, and the Central Cancer Registry case records. We showed how the data on race collected through North Carolina birth and death certificates are translated into 10 fixed racial categories designated by the National Center for Health Statistics (NCHS) for use in official vital statistics. We compared race as reported by the mother on birth certificates to racial tabulations used in the official published birth statistics. We also examined to what extent differences in the determination of race affect measures of racial disparity in maternal and child health indicators. RESULTS: Out of nearly 118,000 live births in North Carolina in 2002, mothers reported more than 600 different versions of race on birth certificates. These entries were collapsed into the 10 standard racial categories outlined in federal coding rules. Approximately two-thirds of mothers of Hispanic ethnicity report their race with a label that can be categorized as "Other" race, but nearly all of these births are re-coded to "white" for the official birth statistics. Measures of racial disparity vary depending on whether self-reported or officially coded race is used. CONCLUSIONS: This study shows that, given the opportunity to report their own race, North Carolinians describe their race using a wide variety of terms and concepts. In contrast, health statistics are usually reported using a few standardized racial categories defined by federal policy. The NCHS rules for coding race should be reexamined. As the ethnic and racial diversity of the United States continues to increase, these rules will become increasingly antiquated.
