What are is considered Northwest Los Angeles, CA?

Answer 1

Geographically speaking, Northwest Los Angeles would be the neighborhoods of Northridge, Porter Ranch, and Chatsworth. That is, if you’re referring to the city of Los Angeles.

However, no one who lives in LA calls it that. There’s Northeast Los Angeles, Downtown, West Los Angeles, East Lost Angeles, South Los Angeles, and The Valley (The San Fernando Valley). The Valley is geographically North Los Angeles.
