When people talk about autism, there’s one perspective that tends to dominate the conversation — how it looks in boys. And I get it, to a point. The research has largely focused on boys. The diagnostic criteria was largely built around boys. So it makes sense that when most people picture an autistic child, they picture a boy.
But autism doesn’t work like that. It doesn’t show up the same way in every person — and if we keep pretending it does, we’re going to keep missing an awful lot of girls.
Why Are So Many Girls Being Missed?
Boys are diagnosed with autism far more frequently than girls — and usually much earlier too. But here’s the thing: that’s not because boys are more likely to be autistic. It’s because the traits boys tend to show match what the diagnostic criteria was originally built to look for.
Girls? They often present completely differently.
And the really cruel part of it is that many autistic girls are so good at hiding their struggles that they slip through the net entirely. They watch, they learn, they copy. They figure out what “normal” looks like and they perform it — all day, every day. This is called masking, and a lot of autistic girls become experts at it from a very young age.
I know this, because I was one of them.
Looking back at my own childhood now, it all makes so much sense. I came home absolutely wrung out every single day. Irritable. Empty. I just thought something was wrong with me. What I didn’t know was that I’d spent the entire day watching other people, working out how to respond, how to act, what to say — so that nobody would notice I felt completely lost.
That’s exhausting work. And when you’re a little girl doing it without even realising that’s what you’re doing? You don’t get support. You get told you’re “shy.” Or “sensitive.” Or — my personal favourite — “a bit dippy.”
So many autistic girls end up being diagnosed with anxiety or depression first, because those are the things that eventually bubble to the surface. The autism underneath them goes unnoticed for years. Sometimes decades.
Socialisation: The Difference Between Blending In and Belonging
Autistic boys often show clearer differences in how they socialise — they might struggle to start conversations, prefer their own company, or show less interest in social interaction generally. Those differences tend to be more visible, which means they’re more likely to be picked up on.
Autistic girls, on the other hand, can appear to be doing absolutely fine socially. They might seem engaged, friendly, part of the group. And on the surface, maybe they are.
But underneath? It’s a different story.
Imagine spending your entire day acting in a play — one where you don’t know all the lines, you’re not entirely sure what the play is even about, and everyone else seems to just know their part instinctively. That’s what socialising can feel like for a lot of autistic girls. They’re working incredibly hard just to appear like they’re keeping up. And by the time they get home, there’s nothing left.
The loneliness of that is something that doesn’t get talked about nearly enough. You can be surrounded by people and still feel completely, utterly alone — because none of it feels real. None of it feels like you.
Strengths Look Different Too
I want to be really clear about something here — autistic girls are not a lesser version of autistic boys. They’re not a quieter, more manageable version of autism. They have incredible strengths. They just don’t always look like the strengths we tend to celebrate.
Autistic boys are often recognised for things like logical thinking, systems, maths, technology. Those strengths tend to be visible and easy to point to.
Autistic girls often have an extraordinary capacity for empathy, pattern recognition, creativity, imagination, and storytelling. Many form incredibly deep connections — with animals, with nature, with art. These things are just as remarkable. But because they don’t fit the picture people have in their heads when they think “autism,” they often go unnoticed.
And that matters. Because when your strengths go unnoticed, it’s very easy to start believing you don’t have any.
The Bigger Problem: What Happens When Girls Go Undiagnosed
When autism isn’t recognised in girls, the knock-on effects can be enormous. Support either comes far too late or doesn’t come at all. Mental health struggles build up over time. Self-esteem takes a battering. And these girls grow up knowing they feel different — just never understanding why.
That last part is the bit that really gets me. Because there is something uniquely painful about spending years feeling like you don’t quite fit, like the world makes sense to everyone except you — and not having a single explanation for it. Not even knowing what question to ask.
And because girls are so underdiagnosed, the research doesn’t reflect their experiences, the resources aren’t designed for them, and the cycle just keeps going.
So What Do We Actually Do About It?
We need to start by accepting that autism is not one-size-fits-all. The diagnostic criteria needs to catch up with what we actually know about how autism presents in girls and women. Masking needs to be recognised for what it is — not as a sign that someone is “managing fine,” but as a sign that someone is working twice as hard just to get through the day.
We need to listen to the lived experiences of autistic women and girls, because they have been telling us this for years. And we need to celebrate all autistic strengths — not just the ones that happen to be the most visible.
Every autistic child deserves to be seen for who they actually are. Not who they’ve spent years learning to pretend to be.
And honestly? So do the autistic adults who never got that chance when they were young.
