Note. Figures in which the numerator is under 20 are deemed as “unreliable.” Overall figures include infants for whom prenatal care was not listed on certificate or those whose prenatal care status was listed as “excluded.” Black, AI/AN, White, and Asian/PI are all non‐Hispanic. AI/AN: American Indian/Alaskan Native; PI: Pacific Islander; SIDS: sudden infant death syndrome; SUID: sudden unexpected infant death. Source.
