Per DNAinfo, the new honor goes to:
Community District 3 — which covers the Lower East Side, East Village and parts of Chinatown — earned the new No. 1 ranking for 2015, the Health Department said.
Well, I didn't see this report online just yet... The department reportedly ranks districts "based on measures of active rat signs, such as fresh tracks, droppings, holes and gnaw marks." (Mmmmmmm)
Anyway, you are welcome CB12!
