Who is the Center of the Hollywood Universe?

Hopefully, you've played around a bit with The Oracle of Bacon and discovered how few steps are necessary to link just about anybody who has ever been in a movie to Kevin Bacon, but could there be some actor or actress who is even closer to the center of the Hollywood universe? The answer turns out to be: yes.

By processing all of the 562.6 thousand actors and actresses in Wikipedia I discovered that there are currently 542 people who are better centers than Kevin Bacon! What does it mean for one person to be a "better" center than another? Consider the following breakdown of people by Bacon Number (as of May 16, 2020):

Bacon Number # of people 0 1 1 861 2 63509 3 240356 4 120927 5 9751 6 761 7 152 8 37 9 16

That means that there is 1 person who can be linked in 0 steps (Bacon himself), 861 people who can be linked in 1 step, 63509 people who can be linked in 2 steps, etc. So we can compute the average Bacon Number as follows:

((0*1)+(1*861)+(2*63509)+(3*240356)+(4*120927)+(5*9751)+(6*761)+(7*152)+(8*37)+(9*16)) / (1+861+63509+240356+120927+9751+761+152+37+16)

= 1387480 / 436371

= 3.180

So the average Bacon Number is about 3.180. We can compare that with the average Jackson Number for actor Samuel L. Jackson. The breakdown is as follows (as of May 16, 2020):

Jackson Number # of people 0 1 1 1616 2 91076 3 257949 4 79393 5 5699 6 488 7 109 8 37 9 3

By computing the average of these numbers we see that the average Jackson Number is about 2.997 making Jackson a better center than Bacon. This is not to denigrate Mr. Bacon, and it should be noted that being the 543rd best center out of 562.6 thousand people makes Bacon a better center than 99% of the people who have ever appeared in a feature film. A list of the 1000 best centers in the Hollywood universe is available for your enjoyment.

Is there a "worst" center (or most obscure actor) in the Hollywood universe? Of course. I won't tell you the name of the person who produces the highest average number---won't you have more fun finding him/her yourself?---but his/her table looks like this (as of May 16, 2020):

XXXXXX Number # of people 0 1 1 1 2 2 3 9 4 15 5 30 6 24 7 97 8 5076 9 92765 10 246622 11 84235 12 6765 13 642 14 68 15 19

for an average of 9.992!
