Twinned with Chicago
31 of 37 in this atlas
Chicago's twinning list spans every inhabited continent, from Accra and Casablanca to Busan and Osaka, Delhi and Karachi to Paris and Prague, Toronto to São Paulo. Nearly all pairings are mutual, with the partner city naming Chicago in return; only New Delhi and Sydney mark the connection one-sidedly. The overall pattern is broad geographic spread paired with reciprocal recognition.
