When it comes to population density, Koreatown is king
It's often said that the Pico-Union district west of downtown Los Angeles has one of the highest density levels in the nation. The neighborhood of old apartment buildings saw a huge influx of Central American immigrants in the 1980s and '90s. But The Times' Mapping L.A. project found that Koreatown actually has a higher population density level.
Population density measures the number of people per square mile.
