[dualvariable]

What is missing is a denominator and some standardization.

There could be 100,000s of people in the US who have jobs where their disappearance could be considered "concerning".

And then we need a base rate for people of similar socioeconomic status. They're probably disappearing at a far smaller rate than the general population, since they're not poor, not sex-workers, not troubled teens, etc. However, there is still a base rate, and you still need to show that it exceeds that base rate--and I kind of doubt that it actually does.

We have a large population, and over the course of a few years 10 weird things happening seems entirely normal to me.
