The average age of a Big Brother houseguest, and how that’s changed

When Vulture’s Joe Adalian asked CBS Entertainment President Nina Tassler if Big Brother will ever again cast someone over 40, the room of TV critics and reporters laughed. Tassler said, “We will absolutely have characters over 40. We didn’t this year.”

That got me thinking: Was it just this year? Or has the show historically cast younger people?

So, I looked at the numbers. The results offered some surprises. (Updated to include the median age, which shows the age that’s in the middle of all the season’s ages.)

Big Brother houseguests ages, 2000 to 2015

season	average age	median age	oldest
1	29.3	26.5	43
2	33.0	30.5	46
3	30.8	29	51
4	28.2	25	58
5	27.4	26	41
6	27.8	26.5	36
7	29.3	30	47
8	26.7	25.5	40
9	26.31	25.5	45
10	33.5	29	75
11	27.4	27	41
12	29.0	27	40
13	31.5	30.5	48
14	30.1	28	42
15	27.1	26.5	37
16	27.4	26	42
17	26.35	26	33

As you can see, over the last five seasons, the average age of the houseguests has decreased, from 31.5 to 26.4–a pretty significant drop. During those five years, there were two seasons with no one over the age of 40.

The oldest season, no surprise, was Big Brother 10, with the totally hilarious Jerry (75) and Renny (53) bringing up the average. The network and producers seem to have lost interest in finding similarly awesome older contestants in recent years.

What surprised me was that the show has been younger than this season (once, and just slightly), but mostly that the average age has gone up and down over time, as you can see in the graph below.

Yet it is clear that this is a very young show. As Jerry and Renny proved, and George before them, diversity in age contributes to entertainment. Life experience shows on the screen, and while I’m not advocating for Big Brother: Golden Girls edition (never mind: YES, PLEASE), the show would benefit from finding older contestants to play.
