Just for fun.

40s= aristocracy
30s=middle class
20s=working class
10s=underclass

I always thought I was middle class until I discovered because I was 16 I am indeed underclass.

and I guess if you’re one of the few who became a mother in your 50s you are a queen

It's all nonsense, for various reasons but here's one - for those of us not having our first child now, it really doesn't apply because times have changed. I had my first child in 1984 at 27, very nearly 28. I was officially an "elderly primagravida", i.e. that's what it said in my notes. Most of my middle class friends were onto their second and third children by that age, having started in their early twenties. Anyone having a first child at or after 40 was regarded variously as a marvel or a freak, whatever class they were seen as. The very few truly posh women I knew then began their families in their very early twenties and went on for longer too.

39.5. Can I be an aristocrat, purleeeese? Grin

VikaOlson · 08/12/2025 11:15

Working class which I am!

zigazigaaaing · 08/12/2025 11:19

29, but solidly middle. At the time none of my friends had children

777holyandsinless · 08/12/2025 11:22

I have a much older half sibling making my mum underclass and my dad middle class. Don’t think trying to explain that to her would go down well 😂

unless it’s different for men because wouldn’t it make old perverts in their 70s having children with women half their age god tier?

Working class - first child at 27 (university educated, post grad, had bought house at 24, married 25). I'm 36 now.

I'd say I'm more upper working/middle though. I'm a solicitor and earn well. DH is a teacher.

FancyCatSlave · 08/12/2025 11:43

Aristocracy

Skint Middle class though IRL. Ex husband has posh ancestry though, his great-great someone was landed gentry and their wife was a lady in waiting.

Hollowvoice · 08/12/2025 11:43

Middle
In reality I'm working class and happened to stumble into a middle class lifestyle!

OttersMayHaveShifted · 08/12/2025 11:45

Middle. But obviously nobody thinks this is the only criterion which determines social class.

Octavia64 · 08/12/2025 11:46

23 so working.

definitelt not. Had just finished my first degree

Pacificsunshine · 08/12/2025 11:47

Middle class which is correct.

I would encourage my own DDs to have children in their 20s, if they can. Children didn’t turn out to be less disruptive to one’s career later. And the benefits of doing it when it is biologically optimal are not to be sniffed at.

whatwouldlilacerullodo · 08/12/2025 11:52

Having kids in your 20s can either mean you're working class OR upper class (at that age you already have a house, income and paid help, so why wait?)

RobinEllacotStrike · 08/12/2025 11:56

Ha ha ha I’ve finally made it. Im aristocracy apparently- where is my pony?

PennywisePoundFoolish · 08/12/2025 12:10

27 so working class. I guess it's broadly right, only GCSEs, work in retail. DH is a tradesman. We have a mortgage and live in an OK area. I grew up in a very middle class town, both parents from quite tough working class backgrounds who got decent jobs and were able to get a mortgage and my dad retired with a very decent pension.

My dad's mum had her first child aged 30, which was considered very late in 1936! She'd been told she wouldn't be able to have children following a bad accident. Her mother was unmarried and was sent away after, and she was raised by her maternal uncle. If she was still alive I'm sure she'd laugh her head off at being categorised as middle-class!

Middle

TheNightingalesStarling · 08/12/2025 10:40

25 so working class.

The time was right. I'm now approaching 40 parenting teens not babies and I wonder how new mums in their 40s have the energy for it but they obviously do. And its their choice.

I guess it depends on your set up. If I'd had a baby in my 20s I'd have had no time and no energy as I'd have been working full time to put a roof over our heads. By my 30s (40 for dh) we had a roof and he could keep it on whilst I focused on the kids.

InMyOodie · 08/12/2025 12:18

Middle.

Greebosmum · 08/12/2025 12:18

Working class

Simonjt · 08/12/2025 12:18

Middle class, but I would be working class when the oldest was born. I’m an immigrant, the UK class system doesn’t apply to me.

MorrisZapp · 08/12/2025 12:21

Middle. Every bit of research bears out that the more educated the woman, the later she starts having kids. Of course it isn't a blanket rule, and nobody serious would say you were underclass simply because you had a baby at a young age.

Allswellthatendswelll · 08/12/2025 12:21

Middle and I am!

But really posh people have their kids in their 20s as they don't have to worry about things like mortgages and career progression. So the theory is off!

Ohthatsabitshit · 08/12/2025 12:23

Proper posh girls have their first child in their twenties on the whole.

GiantTeddyIsTired · 08/12/2025 12:24

Started trying at working class, finally succeeded by middle :) so about right I suppose.

Simonjt · 08/12/2025 12:25

Ohthatsabitshit · 08/12/2025 12:23

My husbands mother is old money, she and all her old money relatives had their first child in their early twenties, especially the ones who married up.

TurquoiseDress · 08/12/2025 12:26

Middle of the middle, first baby arrived when I was 35 and a half 😁
