Top 7 Fastest Growing Towns in Illinois 2026: Where People Are Moving! (2026)

In the ever-evolving landscape of Illinois, a fascinating trend is emerging. As the state grapples with population shifts, certain towns are experiencing remarkable growth, attracting residents and transforming the state's demographic outlook. This article delves into the seven Illinois towns that are witnessing significant population growth, shedding light on the factors driving this phenomenon and the broader implications for the state's future.

Yorkville: A Rising Star in Kendall County

Yorkville stands out as a prominent example of Illinois' population growth. With a remarkable 23.6% increase in residents from 2020 to 2025, it has added 5,111 new inhabitants, reaching a total of 26,730. This surge in population can be attributed to Kendall County's reputation as a hub for westward suburban migration. The town's growth is further fueled by the development of Grande Reserve, a thriving residential community that has been expanding with new residential lots and amenities.

Pingree Grove: Cambridge Lakes' Appeal

Pingree Grove, another Kendall County town, has seen a 21.1% population increase during the same period. The key driver behind this growth is the Cambridge Lakes development, which has been consistently adding single-family homes and townhomes. The strategic location of Pingree Grove, connected to Elgin, Huntley, and the I-90 corridor, makes it an attractive choice for those seeking a reasonable commute to job centers.

Hampshire: A Farm Town's Evolution

Hampshire, located a few miles west, has experienced a nearly identical growth rate of 21.0%. Once a traditional farm town, Hampshire is now undergoing a transformation. The village's planning docket highlights active development projects, such as Prairie Ridge North and Oakstead, indicating a shift towards suburban development. The town's proximity to major highways, including I-90, Route 20, and Route 47, makes it an appealing choice for those seeking a balance between rural charm and urban connectivity.

Manhattan: A Small-Town Haven for Young Families

Will County's Manhattan has witnessed a 16.6% population increase, attracting young families seeking a small-town lifestyle without compromising access to job centers. The town's high share of residents under 18 and above-average household sizes reflect the demographic makeup of its new residents. Manhattan's growth is pushing south, extending its influence beyond New Lenox and Joliet, and creating a desirable commuting distance to regional job centers.

Oswego: A Growing Population Center

Oswego, with a 15.4% growth rate, has seen a significant influx of residents, adding over 5,300 new inhabitants. The town's transformation is evident in the widening of Wolfs Crossing, a project designed to accommodate the expected traffic. Oswego's housing profile, skewed towards owner-occupied homes, and high median household income indicate a thriving community of families. The town's population has quietly shifted from a far-western suburb to a prominent population center.

Elburn: A Metra Station Advantage

Elburn, with a 14.5% growth rate, stands out for its unique feature: a Metra station. The Elburn Station development, a 505-acre master-planned community, offers a blend of single-family homes and low-maintenance village homes. The rail line provides a convenient commuting option for residents, making Elburn an attractive choice for those seeking a town with a downtown feel and easy access to the city.

Warrenville: New Housing Without the Long Commute

Warrenville, an outlier in DuPage County, has experienced a 12.2% population growth despite being in a built-out area. The town's growth is driven by mixed-use developments like Everton, which offers a combination of townhomes, apartments, and commercial spaces. Warrenville's proximity to major highways, including I-88 and Route 59, and its access to DuPage County employers make it an appealing choice for residents seeking new housing without an extended commute.

Conclusion: Illinois' Population Shift

These seven towns represent a broader trend in Illinois, where population growth is concentrated in specific regions, particularly along the outer rim of the Chicago metro area. The availability of buildable land, new subdivisions, and tolerable commutes form a band that is attracting residents and shaping the state's demographic landscape. As Illinois continues to evolve, these towns will play a crucial role in determining the state's future, with wider arterials, school expansions, and townhome developments shaping the growth trajectory.
