The mortality rate is determined by the number of people who have symptoms, and who die from it. The mortality rate is always calculated this way.
There is no way to know the number that never report symptoms. For this disease or any other.

I think that their are some differences, now.
Now, there is a “test”, and tested positives, even asymptomatic, will probably be counted in statistics, reducing mortality. South Korea is massively testing, and I assume quarantining the positives. This gives good control, and also reduces mortality stats, as noted.
Hysteria has the spread of this infection followed, day by day. I would imagine that there is correlation between first-to-show and fatality that skews mortality higher at the start of spread, and we’re seeing this because of the intense focus on rapid day-by-day numbers.
The CDC looks pathetic, in all this. Political hacks and beaurocrats with an unlimited budget. Morons with PhD’s. There seems to be a complete lack of understanding in the CDC of what it’s function even is.
The CDC uses both real numbers and estimates. So the CDC does do a calculation using a estimated number for the number of people who never reported symptoms.
For example, the CDC's 0.1% death rate number for Influenza IS based on an estimate of the number of people who never reported symptoms. And I believe without that estimate, their calculated death rate for Influenza is 0.2%, or double the 0.1% rate.
