For each week beginning on a given date, the figures show the number of sites that reported they are using the zen 6.x-1.0 release.

These statistics are incomplete; only Drupal websites using the Update Status module are included in the data. As this module is now included with the download of Drupal since version 6.x, the data is heavily biased toward newer sites. Read more information about how these statistics are calculated.
