Wikipedia:Good articles was initiated on 11 October 2005, with the current nominations system instituted on 10 March 2006. This table gives a monthly overview of article count, and compares it to that for featured articles. Monthly increases are not the same as new listings, since articles may be removed from both the good articles list and featured article status. Also, good articles that become featured articles are removed from the good articles list. Article counts are those stated on the good articles list and featured article list at 0:00 UTC on the listed date. However, the stated number will sometimes be inaccurate, especially for the good articles.
The number of good articles has been rising faster than the number of featured articles. Whereas the number of featured articles has been rising approximately linearly (at about 55 articles per month), the number of good articles has been rising approximately quadratically: the monthly growth is approximately linear (and currently about 180 articles per month).
The total number of articles on Wikipedia rose exponentially for some time, but since about August 2006, article growth rates have been declining, and now (in 2008) article growth is approximately linear rather than exponential. The number of good articles has been rising as a proportion of the total number of articles, while the proportion of articles featured has stabilized after decline but is slowly increasing again. It has been suggested that article growth is likely to be logistic. In that case, the proportion of GAs will continue to grow linearly for a while, and the proportion of FAs will remain approximately constant. However, both will accelerate as article creation declines.
