Demographics?

Honestly, I did more speeches in high school than I have in two years of college.  I find this shocking.  I never used statistical data in any of my speeches in high school or college.  I was always scared of not finding accurate information and ruining my presentations.  I never used data in any of my high school English classes either, but have in college.  Some of the the sites I come across are obviously not correct and wish I would have had someone to point me in the right direction.  I wish I would have used demographics in those speeches.  Demographics are important characteristics of populations.  Whenever I hear statistics and data information in speeches, it brings a certain professionalism to the topic.  By using information that has been tested and recorded into a survey can be useful at engaging the audience.  By showing facts, the speech will provide more knowledge and hopefully engage the audience to listen.  Verifying the demographics from a reliable source is the most important thing though.  The information that is used must be accurate or the speech will be unethical to use.
