Your reference is very good. It is still a pre-print, but the breakdown is very informative. It estimates the IFR (Table 4)
for ages between 0-34 as 0.01% (1 in 10,000), increasing exponentially from there. The estimated IFR for the next age group, people between 34-54, is between 0.04% and 0.2% (1 in 2,500 to 1 in 500), one to two orders of magnitude greater. For people over 85, the IFR is 36.8% (~1 in 3).
Note that the population over 34 is about 50% of the total in the US.
