Abbreviations: ART = assisted reproductive technology; LBW = low birthweight; VLBW = very low birthweight.
* ART totals include infants conceived from ART procedures performed in 2013 and born in 2014 and infants conceived from ART procedures performed in 2014 and born in 2014. Total ART infants exclude nonresidents and include only infants with birthweight data available.
† In cases of missing residency data (0.6%), the patient’s residence was assigned as the location in which the ART procedure was performed.
§ U.S. births include nonresidents (24).
¶ To protect confidentiality, cells with values from 1–4 are suppressed, as are data that can be used to derive cell values of 1–4. These values are included in totals.
** In three states, >2% of residency information was missing for procedures performed: California (2.7%), Georgia (2.1%), and Hawaii (2.1%). Overall, residency information was missing for 963 (0.6%) procedures performed and 366 (0.7%) live-birth deliveries.
