Really? New York current has quite a few times the casualties of all of China (10834 vs 3341) with a small population than Wuhan and the casualties haven't stopped there. New York by itself has one of the high casualty levels in the world by any measure.
It has value - it should just be treated very skeptically.
And, honestly, the US numbers are highly inaccurate as well due to a simply lack of an ability to test (instead of a lack of will to publish the real numbers).
The US cannot record data it doesn't have. Covid is only the cause of death if the deceased had Covid; and we cannot know that unless we can test them. In aggragate, we can sidestep this issue by looking at excess death, but that is non-trivial (particuarly because the behavioural changes mean that we would expect other causes of death to differ in unknown ways). At the end of this, I would expect to get fairly accurate estimates for how many died to Covid, but while we are in the middle of it, the numbers are very murky.
At least that is what I could find. I was curious to see if I could find some month to month chart on all deaths for March, February, and January. I could not find one.
No, we don't have solid data on Wuhan. Neither does anyone else outside of China (or so we strongly suspect). The question isn't whether someone has better data than you. The point is that you don't have believable data for Wuhan.
New York started their business closures and stay at home orders 2 weeks after Seattle and California closed down. That’s why they ended up with so many more cases and deaths than the former two.
New York on lockdown is also busier then Seattle on a regular day.
Have you seen any of the photos of the packed subway trains, a week and a half into the lockdown? Seattle doesn't see that sort of thing even in rush hour.
Likewise, if you live in a highrise in New York, you're going to be taking the elevator to go get groceries. Usually with other people...
