How many people know they're autistic, so far.
These are the studies from various countries and teams.
England & Scotland data taken from the official school records.
The problem is, not everyone knows they're autistic.
The tests & assessments tend to find white males/

/because that's what they were expecting to find, many decades ago.
It simply never occurred to people that autism might 'look' different in e.g. females, BAME communities, older people, males who don't present in typically male ways, etc./
I suspect we are nowhere near finding most of the females.
Why do I suspect this? From conversation with diagnostic professionals who are updating their info and having 'oh heck!' moments.
From parents struggling to get their daughters diagnosed, whereas the son was easy/
/...from the number of autistic females I've encountered over the last decades who had gone 'under the radar' for so many years until someone finally had that 'aha!' moment.
And so many with identical presentations who are still struggling to get diagnosed/
Being clear that many diagnostic teams are fabulous.
It's simply a reality that the tools they were given were designed to pick white men.
Let's look at some examples:/
Do they make 'unusual' eye contact?
This can be cultural. It might be immensely rude to look an adult in the eye, in some cultures.

What about their hobbies? Oh she plays with dolls? Great.
Oh, he plays with toy trains? Autism!
Even though the 50 dolls are lined up/
Are they a female that shows sudden changes in mood/angry anxiety? Personality disorder! MH!
Are they a male that shows sudden changes in mood/angry anxiety? Autism!
Repeating, many diagnostic teams are good.../
So many females get to adult years before being considered for diagnosis, dragging behind them a list as long as your arm of Things They Didn't Actually Have But Got Diagnosed With before someone said 'oh...ah...!'
So, when I see prevalence statistics saying it's 4:1 boys/
I am rather suspicious of that number. I really don't think it is.
I think it's far closer.
Colleagues from BAME communities talk of societal and cultural barriers to even thinking about getting a child diagnosed, also/
So...if Scotland has 1 in 40 school pupils who are autistic so far, we can make a good guess that there are more.
And my estimates of 1 in 30 aren't too far wrong.
There's no reason why England should be different; England's rate was the same as Scotland in 2010/
We have various charities still claiming it's 1 in 100, based on data from 10 years ago.
It ignores the data from our own Schools statistical teams.
It's really weird to keep using that figure.
When are we going to stop?

When the university starts sending out teaching evaluation reminders, I tell all my classes about bias in teaching evals, with links to the evidence. Here's a version of the email I send, in case anyone else wants to poach from it.

1/16


When I say "anyone": needless to say, the people who are benefitting from the bias (like me) are the ones who should helping to correct it. Men in math, this is your job! Of course, it should also be dealt with at the institutional level, not just ad hoc.
OK, on to my email:
2/16

"You may have received automated reminders about course evals this fall. I encourage you to fill the evals out. I'd be particularly grateful for written feedback about what worked for you in the class, what was difficult, & how you ultimately spent your time for this class.

3/16

However, I don't feel comfortable just sending you an email saying: "please take the time to evaluate me". I do think student evaluations of teachers can be valuable: I have made changes to my teaching style as a direct result of comments from student teaching evaluations.
4/16

But teaching evaluations have a weakness: they are not an unbiased estimator of teaching quality. There is strong evidence that teaching evals tend to favour men over women, and that teaching evals tend to favour white instructors over non-white instructors.

महर्षि कश्यप की तेरह पत्नियां थीं।लेकिन विनता व कद्रु नामक अपनी दो पत्नियों से उन्हे विशेष लगाव था।एक दिन महर्षि आनन्दभाव में बैठे थे कि तभी वे दोनों उनके समीप आकर उनके पैर दबाने लगी।


प्रसन्न होकर महर्षि कश्यप बोले,"मुझे तुम दोनों से विशेष लगाव है, इसलिए यदि तुम्हारी कोई विशेष इच्छा हो तो मुझे बताओ। मैं उसे अवश्य पूरा करूंगा ।"

कद्रू बोली,"स्वामी! मेरी इच्छा है कि मैं हज़ार पुत्रों की मां बनूंगी।"
विनता बोली,"स्वामी! मुझे केवल एक पुत्र की मां बनना है जो इतना बलवान हो की कद्रू के हज़ार पुत्रों पर भारी पड़े।"
महर्षि बोले,"शीघ्र ही मैं यज्ञ करूंगा और यज्ञ के उपरांत तुम दोनो की इच्छाएं अवश्य पूर्ण होंगी"।


महर्षि ने यज्ञ किया,विनता व कद्रू को आशीर्वाद देकर तपस्या करने चले गए। कुछ काल पश्चात कद्रू ने हज़ार अंडों से काले सर्पों को जन्म दिया व विनता ने एक अंडे से तेजस्वी बालक को जन्म दिया जिसका नाम गरूड़ रखा।जैसे जैसे समय बीता गरुड़ बलवान होता गया और कद्रू के पुत्रों पर भारी पड़ने लगा


परिणामस्वरूप दिन प्रतिदिन कद्रू व विनता के सम्बंधों में कटुता बढ़ती गयी।एकदिन जब दोनो भ्रमण कर रहीं थी तब कद्रू ने दूर खड़े सफेद घोड़े को देख कर कहा,"बता सकती हो विनता!दूर खड़ा वो घोड़ा किस रंग का है?"
विनता बोली,"सफेद रंग का"।
तो कद्रू बोली,"शर्त लगाती हो? इसकी पूँछ तो काली है"।
