Some blame taxes as Illinois grows on paper but loses residents

(The Center Square) – Illinois’ population has continued to narrowly grow this year, despite a significant number of cities in the state losing residents to other states.

Some say the trend of increasing tax rates is to blame.

The majority of metropolitan areas in the state have lost residents again in 2025, with Census Bureau data estimates showing only two major areas with any real domestic growth, Rockford and the Illinois portion of the St. Louis metro.

Bryce Hill, director of fiscal and economic analysis for the Illinois Policy Institute, said taxes are driving Illinoisans beyond state boundaries.

“Illinois already imposes one of the highest tax burdens in the country, with the nation’s highest property taxes, among the highest sales taxes, and a 32% income tax increase in 2017,” Hill said. “If state leaders are serious about reversing domestic outmigration, they must focus on tax relief and reducing regulatory barriers to make Illinois more competitive and affordable.”
