Frequently Asked Questions

Where is all this data from?

We compile statistics from such sources as the US Census Bureau, FirstGov.gov, the FBI, Bureau of Justice, and various other governmental and non-profit organizations.

How do I find the source for a particular statistic?

Refer to the 'Source' heading at the bottom of the graph. Or, to list the sources for all our statistics, click on the Sources link at the top right of any page.

How can your graph be valid when it's missing [insert large, important state here]?

First, check you haven't restricted it to a particular set of states or regions by seeing if anything is highlighted in the blue "advanced" form.

The absence of a state in a particular stat does not necessarily imply that state's value is zero (if Maine isn't on a statistic for airports it does not imply there are no airports in Maine). In other cases, such as Capital Punishment stats, the absence of a state does mean that it has a value zero. In these cases, you should consider our graphs only as comparisons of the states that are included in the graph, not of all states.

How can statistic X be valid when it doesn't match up to statistic Y? I did the math!

We use a variety of sources with differing methodologies and definitions. Consult the primary sources to get to the bottom of any conflict. You can do this by looking at the 'Source' entry, at the bottom of any graph

How can statistic X be valid when it's two years old?

We always like to use the most up-to-date information. Often the statistic you see here is the newest you'll find anywhere. There may be nothing more recent available because:
  • The last study on the topic was conducted several years ago.
  • The data has been collected, but not published yet.
  • The data has been published, but not collated across a number of states.

We invite you to look around - if you find something more recent, by all means let us know.

Can I print out copies and use them as handouts in my class?

Yes, provided you keep the StateMaster logo on the page and cite us as the source of your information (if you have to provide a list of citations or bibliography for your class). If you want to print out a graph, be sure to click on the printable version link in the top right hand corner. For an example of a printable page, click here.

Can I quote your information?

You can quote a few individual facts and figures, provided you link back to us. Check our terms or request special permission. Please do not steal entire graphs or State/Category profiles. It's a violation of our copyright.

How often do you update your stats?

We do this every few weeks.

Where do you get your funding from?

Nobody. We are independently owned and run.

Can I link to your site?

Yes. You are most welcome link to us without express permission. All links on StateMaster are supposed to be permanent and we do our best to ensure they stay that way. So feel free to link to any page you like.

How else can I support StateMaster?

You can always join our community of Volunteer Editors. It's flexible and easy, and requires no advanced computer skills. You can add new stats and edit current ones. Contact us if you are interested. Also, be sure to check out NationMaster and join a global community of people interested country-based information. If you don't have any time to be an editor, you can always tell us about statistic sources you may know. Spreading the word is also a great help. Tell your friends, put a link on your website, or nominate us for 'site of the week' somewhere. Thanks for all your support!
