What do you mean the bottom figure doesn't increase? You're confusing me now.
1 is a whole of anything.
1 = 1 whole. 1.3 is adding on 1/3rd. One and a third. 1 and .3 = 1.3
If something is 100% more deadly than it goes from 1 to 2 with two being double of 1. 2 is 100% more than 1 as it's twice the amount of the figure used to represent 1 basically 100% more.
You are looking at it in two different ways at the same time. Saying the figure has increased by 30% of what it was originally is true, but in relation to the ratio that the figure was presented , it isn't increasing by the same proportion.
10 to 13 per 1000 may be an increase of 30% based on the 10 but that is assuming you use the 10 as the figure. If the 10 is in proportion to 1000 then it's not increasing by 30 percent.
It's two different sums you are using at the same time which don't match up , if that makes sense?
If you break it down to 100 for a basic percentage.
1 % increases to 1.3% of the overall ratio. For it to increase by 30% it would go up by 30, or in the 1000 sense, 300.
The 10 is only relative to the 1000. As it means literally 10 per 1000 , so 1% of the figure. To call it a 30% increase its ignoring the base figure that the proportion is determined on.
Or in simpler terms , 10 of what? You have to have a 10 of something to determine a ratio. So you can only increase by the of number to have an accurate increase.
Otherwise 10 increasing to 13 is only increasing by 30% if the total number is 20, rather than a thousand.
that would be correct. if a death rate increased from one/anything to two/anything, it would be a 100% increase.
In the instance we are discussing it's not changing. Whether it's 10 or 100 per 1000 the last number doesn't change. Otherwise the ratio does not change at all, as previously said.
