Actually, the CDC does not provide the data.

The Linked Birth/ Infant Death dataset for 2000 presents tables describing INFANT mortality data by a variety of maternal and infant characteristics.
INFANT mortality rates include live born babies that died in the first year of life. Our discussion has been about NEONATAL mortality rates which include live born babies that died in the first 28 days of life. The BMJ article examines combined INTRAPARTUM AND NEONATAL mortality which includes babies that died during labor and live born babies that died in the first 28 days of life.
The Linked Birth/ Infant Death dataset for 2000 has only one table, Table 6, with information regarding neonatal mortality rates. This table describes neonatal mortality rates based on race and gestational weight only. It does not subdivide neonatal mortality rates based location of birth, gestational age, or the presence/ absence of lethal birth defects.
The CDC data presented in the Linked Birth/ Infant Death dataset for 2000 is not an appropriate cohort of births to compare to the MANA data published in the BMJ.
