Terms of Use
The map layers are freely available for you to use as you see fit. We would appreciate hearing how this is being used and attribution is appreciated! Please email us with a link to your website, GIS projects, or printed materials that you have made using this service.

Note: If you plan to use these layers on a high traffic website, we would appreciate that you download them and host them yourself. As we are currently running this on two VPSes which will be overloaded with too much traffic. Or you could arrange with us to share the costs of our hosting. Otherwise your requests may get extremely slow (because our server will be grinding to a halt) or blocked. On the other hand, I'm not sure what level of traffic would cause a problem and I would love to have a lot of traffic.

If you want a more detailed map (ex. for a local area), different categories or colors, or a tile layer made using another census variable, then you can hire me to do it.
