Background:

  • Multiple births, including twins and triplets, represent a significant portion of annual births in Canada.
  • There has been a notable increase in the incidence of higher-order multiple births over the past two decades.

Purpose of the Study:

  • To analyze trends in twin and triplet birth rates in Canada.
  • To identify key factors contributing to the observed rise in multiple births.

Main Methods:

  • Analysis of national birth data from Canada.
  • Statistical examination of demographic and reproductive technology usage trends.

Main Results:

  • Over 4,000 twin sets and 80 triplet sets are born annually in Canada.

  • Canadian women are 2.5 times more likely to experience higher-order multiple births (triplets, quadruplets, quintuplets) compared to 20 years ago.

    • Conclusions:

    • The rising rates of multiple births in Canada are primarily associated with increasing maternal age.
    • Assisted reproductive technologies and fertility drugs are significant contributors to the elevated incidence of multiple births.
