JP boys’ comics demographics, 2007
Not much text here, just the charts.
Broad-based demographics. Note that V Jump, unlike the others,considers 15-18 rather than 15-17 an age category; thus, also, its “18+” figure is “19+”.
Ages for the four magazines that provide data about the youngest readers. Champion actually reports .1% of its readership in the 3-5 range.
Age demographics for the two magazines with detailed data about older readers. Unfortunately, Sunday doesn’t break things down above age 26.
Of course, along with determining the target ages of the magazines, these also give good information on the target age of works adapted from them.
