Teen Fertility Rates

Date updated: 10/22/2012

Fertility rates are the number of births for a specified age group of females within a certain population or area per 1,000 total females in the age group (Colorado Department of Public Health and Environment).

According to the Centers for Disease Control and Prevention, teen pregnancy costs U.S. taxpayers nearly $11 billion annually for increased health care and foster care, higher incarceration rates for children of teen parents, and lost tax revenue due to lower educational attainment and income among teen mothers. In addition, children of teen mothers are more likely to drop out of high school, have more health problems, give birth as a teenager themselves, and face unemployment as a young adult.

What the above data tell us:

The Larimer County average teen fertility rate for females aged 15 to 17 from 2003 to 2011 remained lower than that of Colorado (13.5 and 21.7, respectively). Rates for Colorado and Larimer County were better than the Healthy People 2010 objective for reduced pregnancies in this age group (43 per 1,000 females aged 15-17). In Larimer County, the number of births to teens between the ages of 15 and 17 is relatively small, ranging from a low of 53 in 2011, to a high of 92 in 2005. For this reason, a 3-year rolling average was used to calculate the teen fertility rates plotted above.

According to the Centers for Disease Control and Prevention (CDC), live birth rates in the United States for women aged 15-17 declined 12% between 2009 and 2010, and the live birth rate for women aged 15-19 was a record low in 2010. Although the reasons aren't clear for these declines, it appears teens are less sexually active, and those who are sexually active appear to be using contraception.

What the above data tell us:

From 2003 through 2011, teen fertility rates for Whites have been lower in Larimer County than in Colorado. The rates for Hispanic teens are significantly higher for both Larimer County and Colorado, due primarily to cultural differences. The number of babies born to teen Hispanic mothers (ages 15 to 17) in Larimer County is relatively small, ranging from a high of 52 in 2005 to a low of 26 in 2003. For this reason, a rolling 5-year average was used to calculate the teen fertility rates plotted above.

In 2003, the United States Certificate of Live Births was revised. National data was provided in revised and unrevised form. The unrevised data was utilized for this report because Colorado did not implement these changes until 2007.
