I think these figures -- especially the last! -- underestimate the
importance of SJ/STB downloads. (I would say that even if I weren't
one of the editors.)

To find equivalent info for R I chose only the biggest, CRAN, and ran a program to count the unique package names (2,849 on 3/25). I then selected all 9 major repositories and ran it again (4,338). So while yearly total number of R packages is known only for CRAN, we can estimate that the growth curve shown in Figure 9 (http://r4stats.com/popularity) is 66% of the total. Individuals still have their own sets, but probably a relatively small number. I would *love* to have similar data for Stata!
