From that exact report you just linked... 77.4 percent of people admitted to the ICU were above age 60. Also you're wrong with your numbers. You skipped females. So in total around 30% of people admitted to the ICU are age 60-69. There's not a whole lot of 80+ year old people considering the average lifespan is mid 70's, so you have to do the per capita math on that.
