The percent isn't useful on it's own though. It needs some basis to know what's going on.
There was a recent Twitter thread where someone was trying to say Vermont was doing worse than Florida because VT has a 98% increase in 14 day Hospitalized while FL only has 24% despite VT having 67% fully vaccinated to FL 52%. Comparing 98% to 24% certainly sounds like it's worse.
The ratio of comments calling them a dumbass was astronomical as they doubled and tripled down on VT being worse.
VT has a daily average of 26 and 4/100K Hospitalized. So, if it was 14 last week and 26 this week, there's the 98% increase. Not great, but hardly the end of the world. Small increases in very small numbers are huge percentage increases.
FL has a daily average of 17,215 and 80/100K Hospitalized. So, if it was 13,880 last week and 17,215 this week, there's the 24% increase. It's a smaller percentage of a huge number.
Those grids had the raw cases and the percent, so there was some context. But, to compare between them, we really need the normalized number for sample size. It does no good to compare something like the 26 VT to 17,215 FL. That looks insanely different. Comparing the 4/100K to 80/100K provides the real context on the gap between them. It still super bad, but not quite as insanely different.
