Milhouse, here are numbers I found for hospitalizations per 100,000 for different age groups. These are from the CDC, posted on April 8. Age 18-49, 2.5; Age 50-64, 7.4; Age 65-74 12.2; Age 75-84 15.8; Age 85+ 17.2.
So clearly, it’s overwhelmingly the elderly who are being hospitalized, right? No, wrong. You have to take into account the number of people in each age group. I found numbers from July 1, 2018. There were 129.58 million age 20-49, 63.16 million age 50-64, 30.48 million age 65-74, 15.39 million age 75-84, and 6.55 million age 85+. (Note that for the youngest group I’m considering, the hospitalizations are for ages 18-49, while the population is for ages 20-49. Those are numbers I found.)
If you do the math, you’ll find that about 7900 were 20-64, and about 7200 were 65+. To summarize, the hospitalization rate is higher for the elderly, but the actual number hospitalized is greater for non-elderly.
