Neither site is clear where the testing capacity goal comes from. For NY, it is 30 per 1k (3%). For Bay Area, it is 200 per 100k (.2%). If my math is right, that's a significant discrepancy.
Actually, I see NY's goal is monthly. So I guess that is more like 30 per 1k per 30 days (.1%).
There some discussion of necessary testing rates in this NY magazine article:
It looks like .2% is at the low end of most ready-to-reopen requirements. In any event, it looks we're nowhere near a test for anyone who wants one.
Also, does anyone know of a good chart that graphs daily new cases vs new tests? It seems like that ratio would be significant, especially when comparing case rates between regions.
As far as I know, it's still the case that no reasonably-large country is doing much more coronavirus testing than the US right now. The UK is probably just about over the 30 tests per 1k per 30 days mark averaged over a week as of our last testing increase, Germany might still be slightly below it but I haven't seen recent figures from them and they seemed to have stalled out increasing testing, and other countries are similar.
FWIW my province of 4.4 million is stalled on tests being run because it's run out of additional symptomatic people to test at around 30 tests per 1k per 30 days, even though testing capacity is about double that, and still increasing.
1. You can't actually randomly choose people, so it's being done on a fist-come, first-serve basis.
2. Testing all asymptomatic people on any regular basis would take orders of magnitude more tests, so it's not useful as a containment measure, just as a data-collection measure.
That ranking's not terribly informative. A lot of the countries heading it up are smaller ones since most countries are drawing from the same global pool of testing consumables, meaning that there's not much relationship between the difficulty of carrying out a particular number of tests and the size of the country, it's total tests done which doesn't tell you much about current testing rate, and large developed Western countries are close enough in testing rates that an actual ranking based on them probably wouldn't be very stable anyway.
The problem with talking about per capita testing numbers is that having a bigger population means you need a proportionally larger number of tests to administer to reach the same numbers as smaller countries. The will to test and the money to do so aren’t any issue. The problem is that we can’t just snap our fingers and make tens of millions of tests appear out of thin air. I think this point gets lost on a lot of people when they look at the corona scoreboard (likewise, people fixate on the large number of deaths in the US and ignore that we’re doing better than several European nations on a deaths per million basis).

You are correct - but we (or rather the government) can snap it's fingers and compel some private companies that are well positioned to be able to manufacture tests to do so at a higher priority than other business concerns - or we (again the government) can issue generous contracts for testing supplies that guarantees payment to private companies manufacturing them even if the original quota of tests requested by the government is above the level we end up needing.
I think that large countries actually have an advantage here - a small country might not have any internal industry that'd be capable of manufacturing tests without heavy retooling - or that industry might be so small and specialized that scaling it up is infeasible. But even in that sort of a situation they can use market based solutions to bid on tests in a manner that motivates private companies in other countries to feel confident committing to test production - and that's only needed if there isn't any sort of altruistic world-banding-together-to-fight-the-issue effort.

And we’ve done that with things like masks and ventilators. But there is a key limiting factor with the tests, the reagant supply. Again, can’t just snap our fingers and make it happen faster. This isn’t AWS, we can’t just spin up more supply in an instant.
But none of that matters. You have x number of people, you need y number of tests. Just because it's harder to do doesn't mean you need to do it any less.
Yes it does, it’s proportionally more difficult. If you want a country of 300M to have as many tests per capita as a country of 30M, you need _ten times as many tests_.
