***Series Continue Part 3*** I mapped income, rats and the worst apartment building in every Upper Manhattan neighborhood. On one side of Central Park, the worst building has 112 housing violations. On the other, it’s 831.

Central Park isn’t just a park. It’s probably the clearest class divide in Manhattan.
Look around the neighborhoods that wrap around the park. The Upper West Side, Upper East Side, Lincoln Square, Lenox Hill, Carnegie Hill and Yorkville all have median household incomes above $140,000. Then head north into Harlem, Washington Heights, or Inwood and it suddenly drops to somewhere between $28,000 and $77,000. There’s almost no gradual transition. You cross the park, and the numbers change fast. It’s 843 acres of trees separating neighborhoods where income falls by almost two-thirds.
The worst apartment buildings in Manhattan all sit on the poorer side (I guess no surprise ther).
Take 1661 Amsterdam Avenue in West Harlem with 831 housing violations since 2024. Then there’s 681 W. 193rd Street in Hudson Heights with 802. And 241 Sherman Avenue in Inwood has 646.
Now compare that to the wealthy neighborhoods around the park. The most violated building in the Upper East Side has 112 violations. Lenox Hill tops out at 132. Carnegie Hill reaches 125. Same borough. Many buildings from the same era. But the difference is 831 versus 112.
In Upper Manhattan, the biggest complaint is simple.. people can’t get heat.
Heat and hot water is the number one 311 complaint across West Harlem, Central Harlem, East Harlem, Washington Heights, Inwood and Manhattan Valley. Residents are literally calling the city because their apartments aren’t being heated.
Around the wealthy side of the park, it’s different. Illegal parking becomes the biggest complaint. On the Upper West Side and in Lincoln Square, the top complaint is actually helicopter noise. That might be one of the most New York luxury problems there is. (send Mamdani to investigate and impose more tax LOL - Just Joking, so don't hate me on this)
Money doesn’t really solve the rat problem.
The Upper West Side has about 303 active rat sites, and Yorkville has 263. Those are some of Manhattan’s wealthiest neighborhoods.
Meanwhile, Inwood has around 134 and Washington Heights about 116. Rats don’t really follow income. They seem to follow older buildings, dense trash and areas close to large parks. East Harlem still leads Manhattan with roughly 617 active rat sites, but even the wealthy Upper West Side has more rat activity than many neighborhoods in Harlem.
So what?
Downtown Manhattan packed a huge wealth gap into just a few blocks. Midtown barely had one at all and mostly complained to 311 about people making noise or hanging around outside.
Upper Manhattan feels different. The divide is physical. A huge wall of trees separates neighborhoods where household income drops by almost two thirds and where the worst building jumps from about 112 violations to more than 830.
Stand on the 96th Street transverse and in just a few minutes of walking, you can watch New York become a completely different city.
