The disparity between expectations of a prototypical urban form and the urban form of Los Angeles also leads to the relegation of Los Angeles into the cosmopolitan dungeon of non-city status. The lack of a well articulated downtown is perhaps the primary missing element for those who delegate LA to non-cityhood.
