Associate Professor Rebecca Hendrick says residents of those towns could get fewer services and might have to pay higher taxes and fees.
An analysis of 264 Chicago-area municipalities concluded that 70 may face serious financial difficulties that will threaten basic services. The towns include Carpentersville, Round Lake and Woodstock.
The study says another 86 suburbs have to choose between raising revenue or reducing expenditures.
Hendrick predicts those facing the greatest difficulty will be smaller suburbs that have a combination of very low wealth, a high demand for services and already low spending.
