State Fact Sheet Sources
US teen birth rate found in national vital statistics report by year (https://www.cdc.gov/nchs/data/nvsr/nvsr70/nvsr70-02-508.pdf) - 2019
1991 birth rate = 61.8 (https://www.cdc.gov/mmwr/preview/mmwrhtml/mm6013a5.htm)
Percent change in national teen birth rate = (1991 teen birth rate – 2019 teen birth rate)/1991 teen birth rate = (61.8-16.7)/61.8 = 73%
Proportion of teen mothers in US in 2019 (https://www.cdc.gov/nchs/data/nvsr/nvsr70/nvsr70-02-508.pdf)
Add up births to moms aged 15-17: 4725+11862+2494 = 41,081
Add up births to moms aged 18-19: 47473+83120 = 130,593
Add up births from 15-19: 41,081 + 130,593 = 171,674
Calculate % of births to 15-17 years = 41,081 / 171,674 *100 = 24%
Calculate % of birth to 18-19 years = 130,593/171,674 *100 = 76%
% decrease in Iowa teen births between 2016 and 2020
(2016 teen births – 2020 teen births) / 2016 teen births *100 = (1784-1376)/1784*100 = 23%
Statewide teen birth rates calculated by summing total number of births to 15-19 years in each year and dividing by the total population

Adolescent Sexual Health Facts
EyesOpenIowa’s Adolescent Sexual Health Fact information pages are a broad-ranging summary of data covering the sexual health and health-related behaviors of Iowa’s adolescents ages 15-19 years. Both county and our state as a whole data are available below:
Comparing the data:
There are important differences in State of Iowa stats and EyesOpenIowa stats on teen birth rates.
EyesOpenIowa uses the national standard for reporting teen births, which is the birth rate per 1,000 teen girls in the county/state. EOI uses this so that we can compare the differences in the number of teen births between counties of different sizes. It is important to use the national standard, so we can compare Iowa and county specific teen birth rates to each other and nationwide.
The State of Iowa, however, uses the number of teen births per 1,000 BIRTHS in the county. This is not the teen birth rate but is rather the teen birth ratio. The state includes a warning about this on their website but not always on the report of teen birth rate data.
