Birth Defects

Birth defects are physical or developmental conditions that a person is born with. Major structural birth defects affect about 1 in 33 babies born in the U.S. each year, which is about 3 in every 100 babies. The Michigan Birth Defects Registry monitors many birth defects. From Michigan data, we know that between 2015 and 2019 nearly 1 in 100 babies was born with one of the 12 conditions reported in MiTracking. That is a little over 1,000 babies born in Michigan each year with one of these serious birth defects.

Data for 12 birth defects are available on the MiTracking data portal:

  • Anencephaly
  • Cleft lip with cleft palate
  • Cleft lip without cleft palate
  • Cleft palate without cleft lip
  • Down syndrome (trisomy 21)
  • Gastroschisis
  • Hypoplastic left heart syndrome
  • Hypospadias
  • Spina bifida (without anencephaly)
  • Tetralogy of Fallot
  • Transposition of the great arteries
  • Upper and lower limb deficiencies
