I just made a stat of my ISO settings for 3 years (5827 shots analyzed).
ISO 50 = 6 % (Canon G6)
ISO 100 = 18 %
ISO 200 = 16 %
ISO 400 = 30 %
ISO 800 = 21 %
ISO 1600 = 8 %
ISO 3200 < 1 %
I used Exposureplot from this site: http://www.wega2.vandel.nl/ (free)
I always set ISO manually. A minority of shots were taken with the G6 (50 to 400 ISO) or with flash.
For me, choosing ISO is as important as choosing aperture and shutter speed for each type of scene.
Obviously, this kind of statistics is typical of your shooting style and preferred subjects.
