Do we know (at least to an order of magnitude or two) what is the daily creation of black holes in our Hubble Volume?

In the region of the Universe visible from Earth, there are perhaps 100 billion galaxies. Each one has about 100 million stellar-mass black holes. And somewhere out there, a new stellar-mass black hole is born in a supernova every second.

Supermassive, not so many.
