I don't know how these terms are defined exactly, but the BBC claims 71k reported stolen phones in 2025 vs a population of 9.2 million which gives a rate of 7.7 per 1000. There has definitely been improvement but that's obviously above 6. Maybe phone theft isn't counted as robbery?
In any case, recovery rate is the other important metric here especially for justifying a surveillance state, and that has been absolutely terrible.
