Comment Re:Concepcion, Chile: not the second largest City. (Score 1) 374
That Wikipedia article mixes communes (municipalities) and cities. La Florida, 365,563 inhabitants, is not and has never been a city. Puente Alto (492,603 inhabitants) was a separate city 20 years ago, but not now. A conurbation is a fancy name that means currently a city, even if 50 years ago there were many of them.
