<p>Dear OP,</p>
<p>One important thing for you and your dad to understand is that there is no other "walking city" in the united states, although parts of SF and the Loop in Chicago might count. So the density of people - at all hours of the day and night - is likely to surprise both of you. Whereas in most cities, walking around instead of driving at night would mean you're alone and possible prey, in New York, it means you're among a crowd on the streets and are likely safe.</p>
<p>Pickpockets can happen anywhere. Don't do dumb things, and you'll be fine.</p>
<p>Within the actual Columbia neighborhood - 108th to 122nd, Riverside Drive to Amsterdam - the crime rate is the 2nd lowest in the city (behind the UES), for both property and violent crime. You can look at statistics on the NYPD website.</p>
<p>Outside of that, in South Harlem - below 125th st and west of Lexington Ave - it's quite safe although I can see how it would sketch girls out at night, because the people on the street, while harmless, would be a little creepier. And the parts north of 125th or east of Lex are in fact much more dangerous. But Columbia students rarely have any reason to go to South Harlem, much less the tougher neighborhoods. I used to go from the north end of campus to the B/D train stop on 125th st to take the subway to Yankee Stadium, and in doing so I'd pass two grocery stores, a block of restaurants, the School of Social Work, and a community housing project with kids playing in a playground outside. It doesn't exactly go "abandoned lot, liquor store, gun store, abandoned lot". Columbia is not in the ghetto.</p>
<p>In terms of general NYC safety, the ordinary person has nothing to fear during ordinary hours unless they're doing something extraordinarily stupid. For example, cabs, while a little crazy, are in fact always in control - they will not hit anybody unless the person does something really unexpected. Don't leave your wallet in an obvious pocket of your backpack, and leave your backpack on your back in a crowded subway. Don't go running in a park after dark (although, in the case of Central park, you actually could and you'd be fine). Follow some simple, common-sense logic and you'll feel absolutely no different than being at home in the pasty-white burbs. I'm from there too, and aside from learning to always lock my doors, I adjusted fine.</p>
