Abbreviations: ART = assisted reproductive technology; LBW = low birthweight; MLBW = moderate low birthweight; VLBW = very low birthweight.
* ART totals include infants conceived from ART procedures performed in 2015 and born in 2016 and infants conceived from ART procedures performed in 2016 and born in 2016. Total ART infants exclude births to nonresidents and include only infants with birthweight data available.
† In cases of missing residency data (0.4%), the patient’s residence was assigned as the location where the ART procedure was performed.
§ U.S. births include births to nonresidents. Source: CDC Wonder [Internet]. Natality public use data 2007–2016. Atlanta, GA: US Department of Health and Human Services, CDC; 2018.
¶ 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.
