*In cases of missing patient's residence data (0.4%), it was assigned as the location where the ART procedure was performed.
†ART totals include infants conceived from ART procedures performed in 2018 and born in 2019 and infants conceived from ART procedures performed in 2019 and born in 2019. Total ART births exclude births to non-U.S. residents and include only infants with gestational age data available.
§U.S. births exclude births to non-U.S. residents. Source: National Center for Health Statistics, Vital statistics data available. Natality public use file and CD-ROM. Hyattsville, MD, National Center for Health Statistics.
To protect confidentiality, cells with values of 1–4 for ART infants and cells with values of 0–9 for all infants are suppressed. Also suppressed are data that can be used to derive suppressed cell values. These values are included in the totals.
