Uh, Voyager aired in 1995 so if you’re 30 now, you would be 1 year old when it aired. Would have been 2 years old when Janeway and Paris had lizard sex. Timothée “Paul Wonka” Chalamet wasn’t even born when Voyager premiered.
When Seska was betraying the crew, Square released Final Fantasy 7.
Voyager encountered the Borg and met Seven about when Baby Hit Me One More Time was released.
When Janeway finally got Voyager home, Drake was starting his career on DeGrassi.
Was Ensign Kim over 30 at the start of Voyager? Which series has a cast under 30?
Kim (Garret Wang) was 26. Kes (Jennifer Lien) was 20. Paris (Robert Duncan McNeil) was 30, rounding out the youngest 3 main cast members. The Doctor and Chakotay were the oldest, both at 41.
TNG had Will Wheaton at 15, Denise Crosby (Tasha) at 29, and LeVar Burton at 30. And Stewart (49), Spinner (38), and McFadden (38) as the oldest.
George Takei was the baby of TOS at 29, followed by Koenig (Chekov) at 30 (when he joined a year later, so same age as Takei), and Nichols (Uhura) at 33. Doohan (Scotty) and Kelley (Bones) were both 46 and Shatner and Nimoy both 35. They all lived through WWII (and both Scotty and Bones served, Scotty took some friendly fire on D-day while Bones did training movies for the air force).
DS9 set some new extremes, with Lofton (little Sisko) at 14, Siddig (Bashir) 27, and Farrel (Jadzia) 29. On the other end, Auberjonois (Odo) was 52, followed by Brooks (big Sisko) 44, and Shimerman (Quark) 43.
Enterprise had Park (Hoshi) at 23, Blalock 26, and Montgomery (Travis) 30. Bakula (Archer) was 46, Billingsley (Phlox) 41, and Keating (Reed) 39.
Those are all main cast members, there have been other supporting actors both older and younger than those listed.
