For each week beginning on a given date, the figures show the number of sites that reported they are using the hierarchical_select 6.x-3.1 release.

These statistics are incomplete; only Drupal websites using the Update Status module are included in the data. This module has been included with the download of Drupal since version 6.x so the data does not include older sites. Read more information about how these statistics are calculated.
