Results by ward. The map shows the winning candidate's party affiliations even though aldermen ran as nonpartisans. A white asterisk (*) means the results for that ward were decided in a runoff vote.

This was the first election with the new City Council composed of fifty wards electing one alderman each. Previously there had been 35 wards each electing two aldermen, for a total of 70 seats in the Council. At the time of the election, however, only 61 of those seats were filled. Of those 61 incumbents, 47 ran and 29 were elected to form part of the new council.

All told, despite the nonpartisan nature of the election, candidates affiliated with the Democratic Party won 37 of the seats, while those affiliated with the Republican Party won 13 seats.^[2] 20 runoff elections were held, of which Democrats won 17 and Republicans 3. Two aldermen—Democrat Johnny Powers of the new 25th ward and Republican Joseph B. McDonough of the new 13th—were returned without opposition.^[1]
