Are there any statistic research on peoples' use (count) of each character in the alphabet?

Have you not tried googling for this?

@flutherother – tsk ;-)

Also, you ruined my tada!

flutherother: Oh lord. I almost feel a bit ashamed for not finding this. I actually had a Google session yesterday, but must have been either too absent minded or I might have searched on the wrong things. I’m not English by mother tongue so sometimes it’s hard to get it right.

Good luck with your program, sounds like it will be very painful. (mentally I mean)

I know R S T L N E and C D M A are used the most…

That’s some Wheel of Fortune hotness.

As a cryptogram solver, I know E and T are most frequent.
I also know Spiro Agnew used P and N far more than normal people.

The alphabet in order of its frequency of use in written English: E, T, A, O, I, N, S, H, R, D, L, U, C, M, F, G, Y, P, W, B, V, K, X, J, Q, Z

Taken from a Fact Book I have. Sorry, no percentages.

@hced No problem. Sometimes its just a question of guessing the right search terms.

Does anyone else find it weird that P and B are used less frequently than F, W or G?

Note that the frequencies vary in different languages. You can also find lists of frequencies for two-letter and three-letter combinations (and perhaps more) in various languages. It is interesting to observe how quickly a language’s defining characteristics show up in those lists.

@Provlear, not when you consider the most common words and forms—for instance, “if,” “of,” “for,” and “from,” the “wh” words, verb forms with “will” and “would,” and words that end in “ing.”

Knowing the letter frequency has always been important in solving cryptograms. Tricky cryptograms depart from the usual frequency in some significant way.
