According to Wikipedia's tables, total cases outside of China (as of 3/9/20) are 32,956. Total deaths are: 854. This gives an across the board mortality rate of 2.59%
Personally I don't think that's the true mortality rate. My estimate was based on reading an article by a virus expert predicting 1% mortality rate assuming 40-70% of the world population was infected. My number was assuming only 50% of the population (and only the adult population at that), while lowering the mortality rate from 1 to .5%.
I mean, maybe this expert was wrong, and the assumptions are flawed. But my estimates were on the conservative end of what he was predicting..

That rate of 2-3% is correct as far as the way it is calculated. However like the mean of a model run, it's heavily skewed by one or two members. In this case it's the people over 60 and mostly over 70 that skews the mean.
