It's documented somewhere, but I can't find it with a few minutes of searching. It's wildly racist and classist, but almost certainly true if you ignore "per capita" or other qualifiers.
Higher numbers of people in a location lead to more crimes occurring in that location, so "crime went up when the rail arrived" is almost a statistical certainty. It doesn't address the fact that crime may increase by 10% while the transit population goes up by 50%.
