Drupal.org site statistics

№ 88

Like it or not, but with 2007 around the corner, it is almost reflections and predictions time again. With that in mind, you might find the graphs below to be a source of inspiration.

Line chart of Drupal.org nodes and comments from July 2001 to January 2007, rising to about 100,000 nodes and 178,000 comments.
The past growth in absolute numbers. The "January 2007"-kink is due to the fact that data for December 2006 is not yet available at this point.
Bar chart of Drupal.org yearly growth factors for nodes and comments, from 17 and 47 in 2002 down to between 2 and 3 by 2006.
The past growth in relative numbers. In 2005, the number of nodes and comments grew by more than 300%. In 2006, the number of nodes and comments grew by more than 230%.
Line chart projecting Drupal.org growth to January 2009: comments toward 600,000 and nodes toward 330,000, with R² of 0.9963 and 0.9974.
A growth projection using a polynomial fit (multiple regression). Simply put, the correlation coefficient R-square, is a measure for the quality of the fit. R-square can assume values between 0 and 1, where a value of 1 indicates a perfect fit. Bear in mind that a statistical fit may be anything but an accurate prediction of future growth.
