Data and Statistics

Spina bifida is a birth defect that affects the spine. Read below for the latest national statistics on spina bifida in the United States.

  • Each year, about 1,500 babies are born with spina bifida. [Read article summary]
  • Hispanic women have the highest rate of having a child affected by spina bifida, when compared with non-Hispanic white and non-Hispanic black women. Data from 12 state-based birth defects tracking programs from 1997-2007 were used to estimate the total number of pregnancies affected by spina bifida compared to the total number of live births (also called the prevalence of spina bifida) for each racial/ethnic group:
    • Hispanic: 3.80 per 10,000 live births
    • Non-Hispanic black or African-American: 2.73 per 10,000 live births
    • Non-Hispanic white: 3.09 per 10,000 live births

  • In 1992, the United States Public Health Service recommended that all women of childbearing age consume 400 micrograms (mcg) of folic acid daily to reduce the risk of having a pregnancy affected by birth defects known as neural tube defects (NTDs), which include spina bifida.

In 1996, the United States Food and Drug Administration (FDA) mandated that by January 1, 1998 all grain products labeled as ‘enriched’, such as breads, cereals, and rice, have folic acid added to them to help reduce the risk of NTDs. This is known as folic acid fortification.
    • One study using data from 19 state-based birth defects tracking programs estimated the change in prevalence of NTDs before and after the introduction of folic acid fortification. Overall, a 28% reduction in prevalence was observed for anencephaly (a birth defect of the brain) and spina bifida. A greater reduction (35% reduction) was observed among programs that actively looked for a neural tube defect during a women’s pregnancy (prenatal ascertainment) than for programs that did not (21% reduction).

    • Since folic acid fortification began, there are about 1,300 babies born each year in the United States without an NTD that would have had an NTD if there had not been fortification. [Read article]
