An official website of the United States government

The .gov means it's official.

Federal government websites always use a .gov or .mil domain. Before sharing sensitive information online, make sure you're on a .gov or .mil site by inspecting your browser's address (or "location") bar.

This site is also protected by an SSL (Secure Sockets Layer) certificate that's been signed by the U.S. government. The https: means all transmitted data is encrypted - in other words, any information or browsing history that you provide is transmitted securely.

    Data are Encrypted at all Times

    Our secure servers use Hypertext Transfer Protocol over Secure Socket Layer (HTTPS) to ensure the encrypted transmission of data between your browser and the U.S. Census Bureau. This means that instead of sending readable text over the Internet, both your browser and our servers encode (scramble) all text using a security key. That way, personal data sent to your browser and data you send back are extremely difficult to decode in the unlikely event of interception by an unauthorized party. As a result of this, your browser must be capable of using the required encryption protocol and strength in order to connect to our servers. If you cannot connect to our secure servers, please upgrade to a newer browser.

    Third Party Identity Proofing

    Our secure servers use a digital certificate (digital ID) issued by a trusted, third party Certificate Authority (CA) as proof of identity. The only way to be sure of a web site's authenticity is to view their digital ID. In this way, you can be assured that you are not being "spoofed" or tricked by an imposter. The digital ID will contain information such as the name of the organization that owns the web site, the site's registered internet name/address, and the name of the Certification Authority under which the digital ID was issued. The method for viewing a web site's Digital Certificate/ID varies depending on the web browser. Please see your browser's "Help" information for instructions on how to verify a web site's identity.
