  • * Includes 12 live born infants who died for whom date of death was not reported.

  • Total does not add to 14 627 because for 1390 cases it was unknown whether they had PNC.

  • Data were reported to CDC from 50 states and the District of Columbia on CS case report forms. PR compares the total infants who died (including stillbirths) with those who survived. Percentages are presented in parentheses and are rounded to the nearest whole number. Nine cases did not have a vital status recorded.
