Your wiki page is about crime, but there’s also one about rape:

There was a rape statistics section in my link. I should’ve used an anchor tag so you could see it.

Reasons why it’s likely lower: police refuse to register cases against specific persons or cases from specific people (Dalits), but far more will not be registered simply because the victims don’t even try.

This doesn’t explain why the number would be lower in Uttar Pradesh than the rest of India. In the absence of evidence there’s no reason to believe that police corruption shouldn’t happen in rural areas too.
