From the March of Dimes website:

On an Average Day In the United States

10,830 babies are born

1,420 babies are born to teen mothers

788 babies are born low birthweight
(less than 2500 grams or 5 pounds)

466 babies are born to mothers who receive late or no prenatal care

*411 babies are born with a birth defect

144 babies are born very low birthweight (less than 1500 grams or 3 1/3 pounds)

87 babies die before reaching their first birthday

19 babies die as the result of a birth defect

Note: Numbers are approximations

* Based on a CDC annual estimate of 150,000 babies born with birth defects

Leading Categories of Birth Defects

The estimated incidences for the leading categories of birth defects are
provided in the table below. Birth defects are grouped into three major
categories: 1) structural/metabolic; 2) congenital infections; and 3) other
conditions. Birth defects of the heart and circulatory system affect more
infants than any other type of birth defect. Of all infants born each year,
approximately 1 in 115 has heart and/or circulatory defects.

Birth Defects - Estimated Incidence


Heart and circulation - 1 in 115 births
Muscles and skeleton - 1 in 130 births
Club foot - 1 in 735 births
Cleft lip/palate - 1 in 930 births
Genital and urinary tract - 1 in 135 births
Nervous system and eye - 1 in 235 births
Anencephaly - 1 in 8,000 births
Spina bifida - 1 in 2,000 births
Chromosomal syndromes - 1 in 600 births
Down syndrome (Trisomy 21) - 1 in 900 births
Respiratory tract - 1 in 900 births
Metabolic disorders - 1 in 3,500 births
PKU - 1 in 12,000 births

Congenital Infections

Congenital syphilis - 1 in 2,000 births
Congenital HIV infection - 1 in 2,700 births
Congenital rubella syndrome - 1 in 100,000 births


Rh disease - 1 in 1,400 births
Fetal alcohol syndrome - 1 in 1,000 births

Note: All numbers are based on the best available estimates, which
underestimate the incidence of many birth defects.
