      • Twins 28.8%
      • Triplets or more 3.7%
    • Not able to determine the number of fetuses because the pregnancy ended in an early miscarriage 6.3%
  • Pie chart B represents 29,556 live births. Note: total does not equal 100% due to rounding.
    • Singletons 68.7%
    • Total multiple-infant live births 31.2%, which is subdivided as follows:
      • Twins 29.4%
      • Triplets or more 1.8%
