Standards Compliance

  1. All ICPSR Web pages comply with the U.S. Federal Government's Section 508 Standards, specifically the sixteen rules governing Web-based intranet and internet information and applications.
  2. All static html pages have had a doctype declared (xhtml 1.0 transitional) and are free of syntax errors.


  1. Whever possible, links are written to make sense out of context. Many browsers (such as JAWS, Home Page Reader, Lynx, and Opera) can extract the list of links on a page and allow the user to browse the list, separately from the page.
  2. There are no links that open new windows without warning.
  3. The site uses navigation dropdown menus that appear on mouseover. As an alternative for non-mouse users, static text links have also been provided for all dropdown menu items.


  1. All images used to display meaningful content include descriptive ALT attributes. Purely decorative graphics include null ALT attributes.
  2. Some of our help documentation features screen captures. These screen captures serve to augment the written instructions. The instructions are still understandable if the screen captures cannot be viewed.

Visual design

  1. This site uses cascading style sheets for visual layout.
  2. If your browser or browsing device does not support stylesheets at all, the content of each page is still readable, though the presentation will not be as attractive.
