[MCU] how many powered people are there in the MCU?

We know there’s enough for there to be a dedicated prison for them so presumably there are at least  several thousand just in the US even with a relatively high rate of incarceration. Do we have any indication or guesses as to the total number of people with powers in the MCU both worldwide and in the US?

No way to know for sure. The phenomenon is widely enough known that people immediately understand when they encounter someone who is powered, but rare enough that it's still a surprise.

A couple of government agencies were tasked with cataloging them all.  One terrorist organization specifically targeted them.  At least two enclaves of Inhumans existed - Afterlife and Attilan.

You'd have to decide what criteria to use to consider someone powered, too.  Many people just have high tech gadgets, like Shocker, Diamondback, and Toomes.  Even a lot of Avengers like Stark, Rhodes, Sam, and Clint are normal humans with technological enhancements.  

Then there are combat drugs taken by people like Trish Walker and Simpson.  T'Challa also is technically just a normal human who doses with herbal enhancers and has a high tech suit.

Thousands or tens of thousands is a good guess.
