This database dives into statistics on teen birth rates and connected issues in the state of Washington. All information was retrieved from countyhealthrankings.org unless otherwise specified and is the latest available publication containing data up until 2013. 

Also check out the page with timelines about these topics, ranging from 2006-2013. Find the spreadsheet with selected data here.

Findings

  • There is a large variation in teen birth percentages between counties. Some 5 Washington counties stand out with teen birth percentages of over 6%. 

  • There are clear correlations between a high teen birth rate and a low birth weight, poor health, people living in poverty, college education, high percentage of urban populations, and low percentage of predominantly white populations.

  • Compared nationally Washington state has a relatively low teen birth incidence.

Large variations in Teen Birth % in Washington State

As we can see on the map below, there are large differences between counties. The average is 3.5 teen births per 100 teens, but a few counties have more than 6 teen births per 100. Adams county even has 8.9, which is more than a 250% increase from the average.

Clear correlation between Teen Birth % and Low Birth Weight

The scatterplot below shows a clear correlation between the teen birth % and low birth weight. In counties where the teen birth % is lower we see a lower percentage of low birth weight (and vice versa).

Correlation between Teen Birth % and Income Inequality Ratio

The scatterplot below shows a correlation between teen birth % and income ratio you might not expect: in counties where the teen birth % is lower we see a relatively higher income ratio (which means higher income inequality), and vice versa.

Education Factors

Very clear correlation between Teen Birth % and Education Level

The scatterplot below shows a very clear correlation between the population who had some college and the teen birth %. In countries where the teen birth % is relatively high, less people had some type of college education (and vice versa).
