That would be impossible to find. Only certain jurisdictions voluntarily report certain crimes to DOJ/BJS for tracking (typically violent crimes). That’s the data that makes it into the UCR.
There’s no centralized “database” of state/county/municipal criminal charges for false reports or perjury arrests. There’s also no comprehensive database of civil verdicts for defamation or abuse of process torts arising from false reports. Everything else you might see cited is just nerds guessing and extrapolating.
Studies on false reports have been done, but they are just that. Studies, surveys, etc., limited in scope, duration, and sample size. Best guess, only something like 2% of unsuccessful sexual assault prosecutions are deemed to be “unfounded allegations,” and that 2% includes malicious false reports, reports made too late for physical/medical evidence, and reports of conduct that wasn’t technically a crime but was reported in good faith—with malicious false reports being the rarest.
Didn’t take much searching to find a recent example, though.
Stories like that tend to make local news.
