April 2009 is the first ever Multiple Birth Awareness Month. Since I am so plugged into the multiples community in my area and nationally, my first reaction was, "Why do we need an awareness month?" Multiple birth rates for 2006 were released in January 2009. Here are some highlights:
Twin Birth Rate
The 2006 twin birth rate was 32.2 per 1,000. This remained unchanged from 2005 and 2004.
The number of live births in twin deliveries rose 3 percent between 2005 and 2006 to 137,085 births. This number has more than doubled since 1980 (from 68,339).
137,085 twins were born in 2006
Higher Order Multiples
The rate of triplet and higher order multiple births (quadruplets, quintuplets, sextuplets and septuplets) continued to decrease in 2006. The 2006 rate was 153.3 per 100,000 births compared to 161.8 in 2005 and 176.9 in 2004.
In 2006, the number of higher order multiple deliveries were:
6,118 triplets
355 quadruplets
67 quintuplets
0 sextuplets or septuplets
Multiple Birth Death Rates
Twins are five times more likely than singletons to die within a month of birth. Triplets are nearly 15 times more likely to die within a month of birth. (From 2005 data.)
Impact of Fertility Treatments
Assisted reproductive therapies (including in vitro, ovulation-inducing drugs and artificial insemination) account for 17 percent of all twins and 40 percent of all triplets born in 2004.
Maternal Age Factors
Older women are much more likely to give birth to twins or triplets. One of every five births to women 45 years of age and older was born in twin delivery compared with less than two of every 100 births to mothers 20-24 years of age.
20 percent of births to women over age 45 were twins.
Only 2 percent of mothers 20-24 years of age had twins.
Preterm Birth Rates
A trend towards shorter pregnancies with multiples was observed. The percentage of twins delivered preterm (prior to 37 weeks) rose to 60.4% in 2006. This compares to 11.1% for single birth babies.
Less than 40% of twins were born at 37 weeks or later.
More than 12% were born prior to 32 weeks gestation.
36.33% of triplets were born prior to 32 weeks.
About 80% of quads and higher were born before 32 weeks.

Very interesting to resd the stats on multiples. Thanks for sharing this info, Jess!
This is great information and interesting to read. You really do need a support group of parents who understand what you go through on a day-to-day basis and I'm glad you have that outlet. Because no matter how hard other moms try to empathize, we can't know the unique challenges (and blessings!)you face with multiples.
