<h1>Teen and Young Adult Suicides in the United States</h1>
		<div id="intro">
		<p>The graph below shows the rate of suicide deaths among 15-24 year-olds in each U.S. state between 1999 and 2013. The figures are per 100,000 population, so a rate of 8.0 would mean that for every 100,000 15-24 year olds in the state, 8 of them died by suicide in that year. 
Some regions of interest have been highlighted, but you can highlight any line by mousing over it. </p>
