Chicago vs Phoenix: Cost of Living Comparison
Chicago and Phoenix anchor opposite ends of the climate spectrum, and the migration between them has been substantial for decades. Chicago offers world-class dining, transit, and corporate headquarters, but harsh winters and high Illinois taxes push residents to the desert. Phoenix provides year-round warmth, growing tech and healthcare sectors, and lower housing costs, though summer heat can be as punishing as Chicago's winter cold. Arizona's flat income tax is considerably lower than Illinois's combined state and local rates.
