It doesn't matter if x% of the population is older but if one county has more number of older people and 1% of them get sick, the two FL counties together would still have ~1300 sick people compared to the 400 in Manhattan.
Ofcourse the population density in Manhattan is higher and therefore more vectors for transmission etc.
Another factor here is that NY according to the governor has already reached its peak whereas cases in Florida were still rising the last I read. The number of critical care beds, medical staff etc also matter.
I personally don't mind them opening the beaches with regulations of no loitering, sunbathing etc. We've had the same thing here in Europe and other than a few joggers, the beaches are mostly deserted because there is inherently a higher trust of government and officials in Europe than it is in America. Which is the last thing that matters because once you tell someone in America something isn't allowed, they feel the need to be on the beach because they feel the need to exercise their freedom even if they've never been the type to go there and do the things that are forbidden.
So, there is more risk in New York City in terms of raw numbers of older persons. That's clear from the data. There are more elderly people in New York, and thus more risk (more people who could potentially die from catching the disease). I put the raw count in the post above.
Also, I just got the data for recent positive testing in both New York and Florida. Now this is Florida as a whole (some areas of the state are "on fire", whereas the two counties opening beaches are at a relatively low level with the virus).
From De Blasio's press conference today (Monday April 20), the current percentage of people testing positive for the virus in NYC is 34%. That's really high. So the virus is still there, in force.
Now let's look at the last recorded day of testing in Florida:
https://covidtracking.com/data/state/florida#historical
Sun April 19
9,552 tests completed
727 new positives
7.6% of those tested were positive
Thus, the rate of positive testing in NYC seems to be about five times that of Florida at the moment. New York City is still quite sick, at a level far beyond that of Florida currently.
As far as peaks go, the IHME model (gold standard) says that Florida peaked in deaths about 18 days ago:
https://covid19.healthdata.org/united-states-of-america/florida
So it seems as though each place is (hopefully) beyond its peak in deaths. In that same model, New York is just 4 days past it's peak in deaths. It seems that both locations had the same peak (4 days ago or so) in terms of needed resources peak.
The inescapable conclusion of all this information is that New York City is putting more elderly lives at risk by having Central Park open than the two Florida counties are by having their beaches open. I don't think there's any way around that. There are more could-be-infected elderly in New York City, and the city is still far sicker than is Florida or are the two involved counties.
All that being said, I still think that having Central Park open is feasible, if it's handled right. I don't know if anyone has asked Dr Birx or Dr Fauci about Central Park being open (to get their opinion), but I trust that if the health commissioners of New York state and New York City felt that the situation was untenable, they would shut it down.
People need to get out of their houses and get exercise, IMO, during this crisis. They just need to do it in as smart a way as possible. Hopefully that will be the case in New York City and Florida.
