Hello, Puzzle Pieces!
I figured that since I’ve been gone for a while, I’d return with something fun for this round of Ask an Aspie.
Just last week, I tried to calculate various statistics about the prevalence of ASD for an Editing class assignment. Ultimately, the numbers were cut from the paper, but it apparently didn’t matter. I realized today that my method for finding these statistics was inaccurate.
I had assumed from the data that 1/54 were boys was the same as 1/54 people with autism were boys. That’s where my numbers fell apart.
So what are the actual statistics? Well, here’s what I found out:
US Census Bureau fun-fact: There were an estimated 313,914,040 people living in America in 2012.
I assumed that 1/54 of 1/88 of 313,914,040 was the correct answer for how many males are on the Spectrum in America. I realized today that I was operating under an inaccurate assumption. It’s not 1/54 males with ASD in America; it’s 1/54 boys in America. So I went back to the Census data. What I should have calculated were how many boys there are in America and how many men, then I should have calculated the ASD prevalence from there. Just for inclusivity, I looked up the same numbers for girls and women. Unsurprisingly, the split between male and female in America is just about half. No, really! It’s literally 50.8% female and 49.2% male!
I also discovered in my research that the prevalence is roughly about the same whether we’re talking about adults or children, so I used the same ratios for both groups. That would be 1/54 males and 1/252 females in America.
So now, here are the final numbers broken down in various ways.
313,914,040 people lived in America in 2012.
That makes roughly 3,476,516 people with ASD in America in 2012.
Out of that, 2,863,013 were male, 613,503 were female. Furthermore, 2,647,093 were adult, while 829,423 were children under the age of 18.
To break down these numbers still further:
2,179,959 were men; 467,134 were women.
683,054 were boys; 146,369 were girls.
So, there you have it, people!
The next time somebody says you are one in a million, you can give them the correct statistics.
