The study showed the Chicago region as a whole was estimated to have lost 4,279 people between 2010 and 2019, a 0.05% decrease. The region, with a population of nearly 8.5 million, includes Cook and the five collar counties plus Kendall County.
Over the same time period, DuPage County grew by 2,575 people, or 0.28%. Will County grew by 7,207, or 1.06%, and Kane County grew by 9,502 people, or 1.82%.
Kendall County saw the highest rate of increase of any Illinois county, growing by 6.65%, or 7,860 people…
Growth in Kane, DuPage, Kendall and Will is likely tied to people already in the region moving farther into the suburbs, he said, and to better job growth in the Chicago area than elsewhere in the state.
If one was just reading headlines, this sounds like a big contrast: Chicago is losing residents and suburban counties are gaining them.
The actual estimates present a more complicated story about recent years. Chicago has barely lost any residents. The suburban counties have barely gained any residents. The region as a whole is relatively stagnant regarding population. The state of Illinois has lost a lot of residents but not necessarily from the Chicago region.
Even though this is not a story of massive population loss in recent years in the Chicago region, stagnant populations are usually not regarded as positive. For American communities, growth is good. And populations are not stagnant or declining everywhere; people in Illinois and other locations with population issues can see that other parts of the country are booming. In particular, Sunbelt metropolitan areas are growing at rapid rates.
This is not a new position for the Chicago region. For decades, the city and suburbs have considered the effects of a decline in Chicago’s population (and a rebound for a while) and a growing metropolitan region. Yet, other places are growing faster. Chicagoland is not in the same category as some other Rust Belt metropolitan areas but it is not exactly the attractive location that some other places are.
