Large urban cities. Like a jungle, there is so much going on in large cities and so much depth to tis high rises and train systems underground. Also like jungles cities are loud and alive at night and something is always going on 24/7.

"Concrete jungle" refers to the urban city; first used in cinema by Academy Award winning "The Lost Weekend" (1945), directed by Billy Wilder, starring Ray Milland. Milland's character, Don Birnam, a chronic alcoholic, and binge drinker, speaks of others with the same condition in the "concrete jungle" as the camera pans across a skyline of Manhattan as an epilogue to the story.
Out there in that great big concrete jungle, I wonder how many others there are like me... poor bedeviled guys, on fire with thirst; such comical figures to the rest of the world, as they stagger blindly towards another binger, another bender, another spree.

A semi-racist term for a ghetto.

It's called a concrete jungle because the minorities/high crime-rates represent the 'animal/jungle' part, the 'concrete' part represent the urban area.
