Where did these numbers come from? You linked to a screenshot of a spreadsheet, but not its source.

From a random search, I got 2.8 violent crimes per 1,000 people citywide, which means all 5 boroughs. For just New York county (Manhattan), the most official statistic I could find is 4.57 in 2019[2].
