Miscarriage Statistics

Sadly, miscarriages are a very common occurrence. Sources vary, but many estimate that approximately 1 in 4 pregnancies end in miscarriage; and some estimates are as high as 1 in 3. If you include loss that occurs before a positive pregnancy test, some estimate that 40% of all conceptions result in loss. 

Although statistics can vary slightly from one source to the next, here is a general account (based primarily on information provided by the March of Dimes) of the frequency of miscarriages in the United States:

  • There are about 4.4 million confirmed pregnancies in the U.S. every year.
  • 900,000 to 1 million of those end in pregnancy losses EVERY year.
  • More than 500,000 pregnancies each year end in miscarriage (occurring during the first 20 weeks).
  • Approximately 26,000 end in stillbirth (considered stillbirth after 20 weeks)
  • Approximately 19,000 end in infant death during the first month.
  • Approximately 39,000 end in infant death during the first year.
  • Approximately 1 in 4 pregnancies end in miscarriage; some estimates are as high as 1 in 3. If you include loss that occurs before a positive pregnancy test, some estimate that 40% of all conceptions result in loss.
  • Approximately 75% of all miscarriages occur in the first trimester.
  • An estimated 80% of all miscarriages are single miscarriages.  The vast majority of women suffering one miscarriage can expect to have a normal pregnancy next time.
  • An estimated 19% of the adult population has experienced the death of a child (this includes miscarriages through adult-aged children).
