Why have some of Chicago’s ethnic enclaves vanished? Where do those community members go?

WBEZ’s Monica Eng investigated these questions in an article for Curious City about the disappearance of Koreatown, which used to have a home in Albany Park. 

We speak with Eng about other Chicago neighborhoods: Greektown; Little Italy; Andersonville; the Polish Triangle; and Ukrainian Village. How many people from those groups still live there and why did they leave? And what gives an ethnic neighborhood staying-power.
