Yes, some parts of NY are safe, and NYC is overall safer than other big cities in the US. But NY is an exceptionally unaffordable city. And Brooklyn, where most of NY’s Jews live, has hundreds of murders a year.
Israel’s murder rate is 1.8/100,000, while the US’s is over twice as high, 4.7/100. The US’s rate of robbery is four times that of Israel. NYC’s robbery rate is 243/100,000, while Israel’s is one-sixth of that, 36/100,000.
The traffic fatality rate (in terms of the number of people killed in car accidents per capita) is also much higher in the US.
