In the 2000s, the perceived northern boundary on Park Avenue has edged over 96th Street into what was traditionally Spanish Harlem,[3] leading to that area sometimes being called Upper Carnegie Hill, especially by real-estate brokers.[4] According to the official Carnegie Hill Neighbors website, the Carnegie Hill neighborhood extends from 86th to 98th Streets, from Fifth Avenue up to, but not including, Third Avenue.[5]
