I presume this is an assigment question.
You will find worrying statistics on the CDC (Centers for Disease Control and Prevention) website. This link to suicide rates 2005 to 2009 on rates of people over the age of 65 by ethnicity, sex and race is one example. The CDC offers other information on National Statistics of suicide state by state with additional information.
The New York Times wrote an interesting article on the increases in suicide which you may also find of interest.
