In NYC there's usually ~5100 deaths from 3/11-4/13. This year: 18,551 deaths.

Poisson model results: we're seeing 13900 more deaths than we expect (95%CI: 13200 to 14700).

There were 6589 confirmed covid deaths, 3778 suspected covid deaths (adding these = 10367)

The number of 'excess deaths' exceeds the number of confirmed+suspected covid deaths by about 3000.

Excess mortality is a little abstract though, the number goes up when we think about covid deaths, including those that will never be reported,

and deaths due to avoided medical care for non-covid causes, but goes down when we think about deaths due to air pollution or injury (the lockdown prevents these presumably).
