II. Our Use of Web Measurement and Customization Technologies

We use web measurement and customization technologies to optimize your experience during your visit to our websites and to provide statistically accurate data about how you use our website. These technologies are commonly known as "cookies," and may include the use of persistent cookies and other web measurement and customization technologies.

There are three "tiers" of these web measurement and customization technologies, as established by the Office of Management and Budget (OMB):

Tier 1 - Single Session

This technology tracks the user's online interactions within a single session or visit to a single website. Any information related to a particular visit to the website is deleted from the user's computer immediately after the session ends.

Tier 2 - Multi Session without Personally Identifiable Information

This technology notices when a user returns to a website and remembers his or her online interactions and preferences across multiple sessions, typically for the purpose of web analytics, but also for customizing people's online experience.

Tier 3 - Multi Session with Personally Identifiable Information

This technology is the same as Tier 2, but ties a tracking mechanism to the user's personally identifiable information.

The following sections include information describing the use of these tiers when you visit Census Bureau websites.

Use of Tiers When You Visit Our Websites

VI. Document Accessibility

The Census Bureau is committed to making online forms and other public documents on its Internet server accessible to all. Currently, we are reviewing our websites and making modifications to those pages which are not in compliance with the Americans with Disabilities Act. We use Hypertext Markup Language (HTML) to create pages that are generally accessible to persons using screen reading devices, and we are careful in our construction of HTML documents to ensure maximum accessibility. We include alternate text describing graphics.

Many Census Bureau Internet documents are in ASCII or HTML formats. These documents are accessible to persons using screen reading software. We also have a large number of documents in Adobe Acrobat PDF (Portable Document Format) files. Currently, many people using screen reading devices cannot read documents in PDF format, specifically those that were created from a scanned hard copy.

Adobe Systems, Inc. is producing various products designed to make Adobe Acrobat documents accessible to persons using screen reading software. Adobe's accessibility web pages describe their efforts.

To better serve those with visual disabilities whom are having difficulty accessing PDF documents; you may contact us directly for further assistance at 301-763-INFO (4636), 800-923-8282, or by submitting a request at https://ask.census.gov.
