When searching for statistics, be aware that the most current statistics may be a year or two behind, because information may not be made available to the public at this time. Also, look out for bias.  Statistics can be presented in a way that purposely steers the audience to one side or another.

In addition to the following websites, try doing a Google search for the statistics you need. To only search government sites, use the following technique:

• [search term] site:.gov
• heart attack statistics site:.gov

This will tell Google you only want to see information from sites that end in .gov.
