Example of Information Collected for Statistical Purposes

Below is an example of the information collected based on a standard request for a World Wide Web document:

2005-11-03 12:57:35
The date and time of the request.
The IP address associated with the requestor (you as the visitor). Depending on the requestor's method of network connection, the IP address (or host name) may or may not identify a specific computer. Connections via many Internet Service Providers assign different IP addresses for each session, so the host name identifies only the ISP. The IP address will identify a specific computer if that computer has a fixed IP address.
The site name designated internally by the server for logging purposes. It informs the server that this particular request came through a website located on this server.
GET /contact/index.cfm
The location of the requested file.
The status code. 200 means the request was filled.
The size of the requested file in bytes.
The time required to complete the request in milliseconds.
The protocol used to complete the request.
Identifies the type of browser software used to access the page, which indicates what design parameters to use in constructing the pages.
Identifies the operating system used to access the page, which indicates what design parameters to use in constructing the pages.

Requests for other types of documents use similar information. No other user-identifying information is collected.

Notice of Use

The Privacy Act of 1974 protects the personal information the federal government keeps on you in “systems of records (SOR)” (information an agency controls that can be retrieved by name or some other personal identifier). The Privacy Act regulates how the government can disclose, share, provide access to, and maintain the personal information that it collects. Not all information collected online is covered by the Privacy Act.

The Act’s major provisions require agencies to:

  • publish a Privacy Act Notice in the Federal Register explaining the existence, character and uses of a new or revised SOR;
  • keep information about you accurate, relevant, timely, and complete to assure fairness in dealing with you; and
  • allow you to, upon request, access and review your information held in a SOR and request amendment of the information if you disagree with it.

Your viewing of this website does not result in the collection of any personal information that is contained in a Privacy Act System of Records as defined by the Privacy Act.
