Pages = approx % of pages using that element at least once
Per page = for pages using that element, average uses per page

  Element   | Pages  | Per page
-----------+--------+----------
  <td>      | 90%    | 90
  <ul>      | 30%    | 6
  <cite>    | 0.5%   | 6
  <code>    | 0.4%   | 20
  <blink>   | 0.1%   | 2
  <dfn>     | 0.1%   | 10
  <var>     | 0.05%  | 10
  <kbd>     | 0.04%  | 10
  <samp>    | 0.02%  | 20
  <ruby>    | 0.01%  | 70

Sample size: several billion pages.
Sample date: September 2006.
All numbers rounded to one significant figure.

To put that in perspective, 0.05% of 1,000,000,000 (1 billion) is 
50,000,000.
