PDF is huge in Government and Education

Duff Johnson posted a survey, 98% of .com is HTML but 38% of .gov is PDF!, showing that PDF documents are far more prevalent on public sector (.gov) and education (.edu) websites than on commercial (.com) sites.

Share of HTML and PDF file formats on the world wide web:

    • .com: HTML 98.7%; PDF 1.0%
    • .gov: HTML 46.9%; PDF 37.9%
    • .edu: HTML 44.6%; PDF 26.7%

The numbers are striking, and illustrate the tremendous importance of PDF accessibility for government and educational institutions in their service of the public.
