ART = assisted reproductive technology; SGA = small for gestational age (22-44 weeks), defined as <10th percentile of birthweight for gestational age week.
*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.
