NYC certainly got hit bad, but I wouldn't say it's the only badly hit city. Here is deaths/total pop for some other cities >1mil population which I would also call "hit hard".
I'm using the per-mille (‰) rather than per-cent (%) symbol. Sorry for the confusion, but it's a more convenient unit for these quantities. This is how it'd look in percentages:
I've never seen that notation in my entire life. Learn something new every day.
Just want to point out that you didn't call that out explicitly. 99% (note that it's a percent) of people who saw your comment would see it and view it as a percent. I did, and I work with data all day every day.
It's unintentionally misleading to use notation like that without calling it out.
You're right, I should have called it out in the text. I thought ‰ was okay because I was comparing the other cities to NYC, not to an absolute value. Also, I think it's a fun symbol, and I want more english speakers to use it.
NYC: 1.07‰
New Orleans: 0.65‰
Detroit: 0.60‰
Boston: 0.44‰
