Frequently Asked Questions

Q.

For indicators that stratify by race and race/ethnicity how are race and ethnicity determined?

A.

Data provided by race and race/ethnicity reflect the race and ethnicity of the mother as indicated on the birth certificate. Race categories shown on PeriStats include: White, Black, Native American, and Asian, consistent with those reported by the National Center for Health Statistics (NCHS). Race/ethnicity categories include: non-Hispanic white, non-Hispanic black, non-Hispanic Native American, non-Hispanic Asian/Pacific Islander and Hispanic. Race and ethnicity are reported separately on the birth certificate. When race of the mother is missing from the birth certificate, NCHS imputes race using race of the father, if available, or by assigning the specific race of the mother on the preceding record with a known race of mother (0.3% of live births in 2001).
