The slowdown in population growth in Illinois is a cause for concern, especially as it lags behind its Midwest peers. While the state's population grew by a modest 16,108 residents between July 2024 and 2025, this is a significant decline from the previous year's growth of nearly 70,000. But here's where it gets controversial: the impact of international immigration is a key factor in this slowdown. New York, for instance, experienced an even sharper decline in growth, slipping from an increase of 214,876 residents in 2024 to just 1,008 last year. Nationally, the rate of population growth fell by half to 0.5%.
The decline in immigration is reducing one competitive advantage the state has enjoyed over its neighbors. Illinois had nearly twice the number of international immigrants in 2024 as Ohio and Michigan, despite having similar overall population numbers. In 2025, the gap narrowed to 1.5 times. But what's the real reason behind this decline in immigration?
Population growth is a barometer of economic health, fueling increased consumption of goods and services, as well as tax revenue. Illinois has had sluggish growth in the past three years and saw declines in the two years before then. Gov. JB Pritzker, who is seeking election to a third term this year, touted the growth. "Illinois recorded its third consecutive year of population growth, as the state remains focused on strengthening the factors that help people choose to stay and build their lives here," he said in a statement. But what's the real reason behind this growth?
The outflow of residents to other states, or what the Census Bureau calls domestic outmigration, continues to plague Illinois. The exodus slowed by half in the past two years, but Illinois still lost 40,000 residents to other states in 2025. What's the real reason behind this outflow?
