Where People Are Moving To In Illinois In 2026

New streets, new schools, new neighbors. A handful of Illinois towns are in full growth mode, and the latest Census estimates show exactly where. Nearly all of them sit on the outer rim of the Chicago metro, in counties where corn fields are still turning into cul-de-sacs. Yorkville leads the pack among places with at least 5,000 residents in 2025, and the gap between it and the rest of this list is smaller than you might expect. The seven towns below are where Illinois is actually adding people.

Yorkville

Yorkville added 5,111 residents between 2020 and 2025, growing from 21,619 to 26,730. The 23.6% increase comes with one of the largest raw gains in the state, and it fits Kendall County's long-running role as the place where westward suburban migration lands.

Grande Reserve remains the workhorse. The city recently reviewed final plats for Units 10B and 11B, roughly 20 acres and 154 residential lots east of Kennedy Road and south of the BNSF tracks. Route 47 carries commuters toward the western suburbs, and the retail strip along it has filled in as the rooftops multiplied. Schools, stores, and subdivisions have been feeding each other here for years.

Pingree Grove

Pingree Grove grew 21.1%, from 10,356 residents in 2020 to 12,545 in 2025, and the short version of why is that Cambridge Lakes keeps building. The sprawling residential community has been adding single-family homes and townhomes for years, and D.R. Horton is still selling in Cambridge Lakes North, ranch plans included. Route 72 connects the village to Elgin, Huntley, and the I-90 corridor, so the new households aren't stranded out in Kane County; they're a reasonable commute from jobs that already exist.

Hampshire

A few miles west, Hampshire posted a nearly identical rate: 21.0%, climbing from 7,659 residents to 9,266. Hampshire was a farm town within living memory, and parts of it still look the part, but the village's planning docket says otherwise. Prairie Ridge North, Oakstead, and the Light Property annexation and zoning project are all listed among its active development items. With I-90, Route 20, and Route 47 nearby, Hampshire has the highway access of a suburb and, for now, the land of farm country. That combination rarely stays cheap for long.

Manhattan

Will County's entry on the list is Manhattan, up 16.6% from 9,386 residents in 2020 to 10,943 in 2025. Growth here is pushing south past New Lenox and Joliet, close enough for a regional commute but far enough out for bigger lots and newer houses. D.R. Horton's Ivanhoe community is selling single-family homes in the village now, and the Census profile fills in who's buying: Manhattan has a high share of residents under 18 and household sizes above the state average. This is where young families land when they want a small-town layout without giving up access to the job centers up the road.

Oswego

Oswego's 15.4% growth rate is the more modest figure on this list, but the raw number isn't. The village added more than 5,300 residents, going from 34,618 in 2020 to 39,948 in 2025, the biggest headcount gain of any community here.

You can see the strain on the road map. Wolfs Crossing is being widened with new lanes, reworked intersections, sidewalks, and bicycle facilities, a project sized for the traffic Oswego expects rather than the traffic it used to have. The housing profile skews heavily owner-occupied and median household income runs high, which translates to family money buying family houses along Route 34 and the corridors feeding it. At nearly 40,000 people, Oswego has quietly stopped being a far western suburb and started being a population center.

Elburn

Elburn grew 14.5%, from 6,188 residents to 7,084, and it holds a card most towns this far west don't: a Metra station. Elburn Station, the 505-acre master-planned community Shodeen Homes is developing near the Anderson Road and Keslinger Road intersection, is literally named for it. The project mixes single-family homes with low-maintenance village homes, and the rail line lets buyers commute into the city from a town that still has an actual downtown on Route 47. For a village of 7,000, that's an unusual setup, and it's working.

Warrenville

Warrenville is the outlier here. It sits in built-out DuPage County rather than on the metro's edge, yet it still grew 12.2%, from 13,557 residents in 2020 to 15,211 in 2025. There's no farmland left to convert, so the growth has come project by project. Everton, a mixed-use development, brought 89 townhomes, a 259-unit apartment complex, and commercial space. Cantera Point, a 91-townhome proposal on MaeCliff Drive, has advanced through city review. With I-88, Route 59, the Illinois Prairie Path, and DuPage County employers all close, Warrenville is picking up residents who want new housing without an hour-long commute attached to it.

Where Illinois' Growth Is Heading

Put these seven towns on a map and they trace an arc through Kane, Kendall, Will, and DuPage counties, the band where buildable land, new subdivisions, and tolerable commutes still overlap. The next few years will test how well that band keeps up: wider arterials like Wolfs Crossing, school expansions, more townhome proposals in front of village boards. Much of the rest of the state is flat or losing people. Within Illinois, the population is going where the houses are.
