colonist lifespan question

[LorimerLonghaul]

anyone know how long colonists spend as children, youths, adults, middle-aged and seniors? are they equal portions of the colonist's lifespan?

i'm specifically curious about being able to tell at a glance about population management, ie wondering if i have enough children and youths to replace my seniors and middle-aged.

if they're all equal portions of the lifespan, then true equilibrium would mean having an equal number of each.

Of course, each playthrough i've done i've had the huge population explosion and this hasn't been an issue, but on my next playthrough i'm hoping to try some rather draconian and micro-managey experiments in pop control

From my own observations.
Children = only 4 sols. I have found a martian being a teenager with only 4 sols on Mars.
Then they turn teenager, they stay teenager from sol 4 to sol10-sol14 i don't know the precise number. I'm sure about having martian adults at sol 14.
They turn adults from sol 14 to sol 32. At sol32 they turn middle aged.
And they probly turn old around sol60.
After that they can probly live 15 maybe 20 sols, i've old people still alive at sol 72-74.

I had a breakthrough that made your seniors continue working. That messed up my retirment dome. Saw a researcher at 73 still going strong.

Forever Young is one of the best breakthroughs. I love getting it.

Fantastic breakthroughs, but the killer when you have the baby explosion happening

Wow I just realized a sol is 687 days long. Almost 2 years, of course you become a teenager near the end of your fifth sol, duh. Those numbers weren’t making sense at first, I was thinking 12 Earth months instead of the 22+ months per sol. And on top of that, months make no sense without the Moon in orbit. And Mars day is half hour longer? Woah, mind blown.

Edit probably better to go to France’s revolutionary calendar with 10 day Decades instead of the quarter moon based week.

Looking it up it says 668.5 local days per sol year. This means we would get 66 decadal weeks plus a short week, or 95.5 weeks if the calendar stays at 7 Martian days.
