The data were compiled using Wayback Machine captures. No snapshots of Template:Articles lacking sources progress could be found prior to August 2009; thus this table only records monthly counts from then onward. Each monthly category is listed in the leftmost column, while the top row documents the date on which each category's count was recorded.

Monthly categories that did not yet exist or were being populated at the time of the capture are left blank.

Anomalies

• December 2009's subcategory once contained a staggering 110,847 articles. Only a tiny portion were actually created in December 2009. The vast majority were created at various dates, but only flagged as part of a large-scale automated search for unreferenced articles. After some discussion whether to track the ~110,000 articles with maintenance tags or with a less-obtrusive hidden category, the former approach won out, and User:Rich Farmbrough ran a bot to tag all the articles and place them in the December 2009 subcategory.
• Despite being previously cleared, the October 2006 subcategory had a single article outstanding in February 2019. PRADAN was restored to its unsourced 2007 version after later versions were found to be copyvios. The article was promptly listed for deletion.
