The correspondence between interracial births and multiple-race reporting

Area of Science:

• Demography
• Public Health
• Sociology

Background:

• Race-specific health statistics are common, often highlighting disparities.
• The U.S. Census 2000 indicated 2.4% of the population identified with multiple races.
• Interracial births are a key factor in understanding multiracial population dynamics.

Purpose of the Study:

• To test the hypothesis that multiple-race reporting correlates with interracial births.
• To compare parental race data from birth certificates with national health survey responses.
• To assess the accuracy of vital records in estimating the multiracial population.

Main Methods:

• Comparison of U.S. natality data (1968-1998) with National Health Interview Survey data (1990-1998).
• Analysis stratified by year of birth to account for temporal trends.
• Evaluation of parental race reporting consistency between datasets.

Main Results:

• Survey responses for multiple-race identification largely correspond with patterns of interracial births.
• Specific combinations of multiple-race reporting exhibit notable discrepancies when compared to birth records.
• The association between interracial births and survey-reported multiracial identity is not uniform across all racial pairings.

Conclusions:

• Vital records provide an incomplete basis for projecting the size of the multiracial population.
• Understanding multiracial demographics requires integrating data from both vital records and health surveys.
• Discrepancies highlight the complexity of race and ethnicity reporting in the U.S.
