This is a chart I did a number of years ago using my ratings showing the number of players in tenth of a point buckets.
You can see at 2.5 and 3.0 there are more players at the top of each range than the bottom by a pretty wide margin.
At 3.5 it is pretty balanced, but note that this chart included men and women so there is a peak of 3.0/3.5 women overlaid with the peak of 3.5/4.0 men.
At 4.0 there are more in the lower part of the range, but again this is in part due to men and women in the same chart. Clearly at 4.5 and above there are more at the lower end which is what I was saying earlier.
