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 4.6 million people in the Internet Movie Database I discovered that there are currently 455 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 March 6, 2017):

Bacon Number# of people
0 1
1 3421
2 396124
3 1459238
4 375038
5 32744
6 3830
7 575
8 115
9 23
10 7

That means that there is 1 person who can be linked in 0 steps (Bacon himself), 3421 people who can be linked in 1 step, 396124 people who can be linked in 2 steps, etc. So we can compute the average Bacon Number as follows:

((0*1)+(1*3421)+(2*396124)+(3*1459238)+(4*375038)+(5*32744)+(6*3830)+(7*575)+(8*115)+(9*23)+(10*7)) / (1+3421+396124+1459238+375038+32744+3830+575+115+23+7)

= 6865457 / 2271116

= 3.023

So the average Bacon Number is about 3.023. We can compare that with the average Jackson Number for actor Samuel L. Jackson. The breakdown is as follows (as of March 6, 2017):

Jackson Number# of people
0 1
1 7025
2 585124
3 1412368
4 241855
5 21395
6 2825
7 410
8 97
9 10
10 6

By computing the average of these numbers we see that the average Jackson Number is about 2.866 making Jackson a better center than Bacon. This is not to denigrate Mr. Bacon, and it should be noted that being the 456th best center out of 4.6 million 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 in the IMDb---won't you have more fun finding him/her yourself?---but his/her table looks like this (as of March 6, 2017):

XXXXXX Number# of people
0 1
1 6
2 2
3 2
4 1
5 2
6 3
7 12
8 104
9 4322
10 364874
11 1398444
12 459637
13 38466
14 4484
15 635
16 113

for an average of 11.079!
