It helps put in perspective on just how many addicts there are.

Using a number like 25000 is difficult to understand in your head.

4 years is a lot of time!

You probably see or are aware of high school age individuals throughout your day-to-day.

Now imagine for every 1 high school age young-adult, your city also has 1.5 injection drug addicts.

I think that puts things in perspective pretty well.

For a city like SF, probably more illustrative to show how many addicts there are for each programmer or Tesla.
