Ken may perhaps have forgotten that the 4.0 figures wrongly count five
format characters as graphic characters, and so after adjusting for
the longstanding out by two error the 4.1 figures for format
characters are still out by four due to the change in GC of U+200B to
Cf in 4.0.1. By my calculations the correct values for 4.1 are:

Unicode 4.1:

51640 graphic characters assigned (BMP)
35 format control characters assigned (BMP)
65 control characters assigned (BMP)
6400 private use characters assigned (BMP)
2048 surrogate code points designated (BMP)
34 noncharacter code points designated (BMP)
5314 reserved code points (BMP)
45875 graphic characters assigned (supplementary planes)
105 format characters assigned (supplementary planes)
131068 private use characters assigned (supplementary planes)
32 noncharacter code points designated (supplementary planes)
871496 reserved code points (supplementary planes)
------------------------------------------------------------------
1114112 code points altogether

Based on the latest publicly available version of the 5.0 UCD data, I
get the following figures for 5.0. My figures have two less BMP and
two more SMP characters than Ken's figures, but I haven't
cross-checked with N2991 yet (N2991 states there are 1,359 new
characters, but this must be a typo for 1,369), so I'm not sure who's
correct.

Unicode 5.0:

51980 graphic characters assigned (BMP)
35 format control characters assigned (BMP)
65 control characters assigned (BMP)
6400 private use characters assigned (BMP)
2048 surrogate code points designated (BMP)
34 noncharacter code points designated (BMP)
4974 reserved code points (BMP)
46904 graphic characters assigned (supplementary planes)
105 format characters assigned (supplementary planes)
131068 private use characters assigned (supplementary planes)
32 noncharacter code points designated (supplementary planes)
870467 reserved code points (supplementary planes)
------------------------------------------------------------------
1114112 code points altogether
