Update 2 (July 15, 2014): New, more accurate data is here.

Update (Jul 1, 2014): This post doesn’t measure releases in 2-week totals, which turns out to be a huge deal in many, many cases. I’m currently working on an updated version of both this and the other 2011-2012 manga boost posts. Just be aware of that before citing the data from here regarding any one show.

Way, way back, I published an article looking at how anime adaptations produced in early 2012 affected the sales of their source manga. It was interesting data to take a look at, and it was interesting to see which anime really boosted the manga sales. Long story short, there are cases where a manga really jumps from mid-tier to franchise level (Space Brothers, Kuroko’s Basketball, Inu x Boku SS) soon after the anime airs, and cases where the anime doesn’t have much visible effect.

Also way back, I started pulling sales records for manga that had an anime adaptation air in 2011, to get a better idea of how the two media are interrelated. This post contains the second half of that data, specifically the data for which I have maximum constraints for series before they aired, and at least one solid instance of making the Oricon charts afterwards. These aren’t quite the tier of hits in the first part of the data, but they’re more marginal, which makes the charts pretty interesting by themselves.
