Alpha Epsilon Pi has 123 Active chapters and 8 colonies with 189 chapters internationally including dormany chapters and approximately 80,000 brothers. I don't know how many alumni chapters there are really.

While I would never shoot the messengar, I'm confused as to the statistics slightly...

Here are two separate lists. The first list is of fraternities with more than 100 chapters. (I did not include colonies or affiliates) The second list is fraternities with more than 100,000 total initiates.

Please do not shoot the massager here. I got the following statistics from the Fraternities Executives Association's web site. Last updated on Monday, May 17, 2004.

My understanding is that each fraternity's information is provided by the fraternity. So how up to date the statistics may be is depended on each fraternity.

FYI: From the information provided, you can not divide the total number of initiates by number of chapters to get an average chapter size. The number you would get would be the total number of initiates per chapter. To get the historical average chapter size you would then need to divide that number by the total cumulative number of years for all active chapters.

To find the current average chapter size, you would need to know the number of current active members divided by the current number of chapters. The web site does not provide this information.

For example. Fraternity ABC is listed with two chapters and 120 initiates. Chapter A has had 60 members for 3 years while Chapter B has had 60 members for 2 years. If you were to divide 120 by 2 you would come up with 60. But the accurate chapter average would be 24. How would you get there is to divide 120 (total initiates) by 5 (each active year of each chapter - 3 for Chapter A and 2 for Chapter B.) Thus 120/5 = 24.

Perhaps you can you tell I'm a statistics nerd.
