If you’re driving through the Fox River Valley, you might think you know Elgin. Maybe you see the historic architecture or the Grand Victoria Casino and figure it’s just another quiet Chicago suburb. You’d be wrong. Honestly, the demographics of Elgin IL tell a much more colorful and, frankly, surprising story than the typical "commuter town" narrative suggests.
It’s a city of 114,701 people as of the latest 2024 estimates. That makes it the sixth-largest city in Illinois. While places like Springfield and Peoria are nipping at its heels, Elgin has carved out a unique identity that’s younger, more diverse, and more "international" than most of its neighbors in Kane and Cook counties.
The Cultural Mosaic: Why Elgin Isn't Your Average Suburb
Diversity isn't just a buzzword here. It's the reality of standing in line at a grocery store on Summit Street. Unlike many nearby suburbs that lean heavily in one direction, Elgin is remarkably balanced.
Hispanic or Latino residents make up about 48.4% of the population. That's nearly half the city. If you look at the raw numbers from the U.S. Census Bureau, about 55,300 people identify as Hispanic. But don't let that overshadow the rest of the mix. Non-Hispanic White residents account for roughly 36.3%, while the Asian community (5.9%) and Black community (5.2%) round out a population that is constantly evolving.
There’s a massive global footprint here. About 26.3% of the people living in Elgin were born outside the United States. That’s double the state average. When you walk through the neighborhoods, you’re hearing a dozen different languages. In fact, nearly 48.6% of households speak a language other than English at home. That's not just "kinda" high—it's one of the highest rates in the region.

Money and Work: The $88,316 Middle Class
Let’s talk money. The median household income in Elgin hit $88,316 in 2023, which is actually a 2.7% jump from the year before. People are working. The unemployment rate was sitting around 4.5% in late 2025.
But where are they working?
Manufacturing is still the king of the local economy. More than 10,000 residents are clocked into manufacturing jobs. After that, you've got a huge chunk of the population in Health Care and Social Assistance (over 6,000 people) and Retail. It’s a blue-collar heart with a growing white-collar nervous system.
Interestingly, the "work from home" trend hasn't hit Elgin as hard as it has the Loop. Only about 10% of workers are staying in their pajamas all day. The rest? 73% are driving alone to work, facing that infamous Fox River traffic every morning.
A Quick Look at the Numbers
- Median Age: 36.3 years (much younger than the state average of 39.5)
- Home Ownership: 71.4% (people here aren't just renting; they're buying)
- Median Home Value: $252,400 (though more recent 2024-2025 market trends show this climbing)
- Education: 81.2% have a high school diploma, while 26% hold a Bachelor’s degree or higher
The Age Factor: A City of Families
Elgin is young. Seriously. With a median age of 36.3, it’s significantly "fresher" than the rest of Illinois. You see this in the schools and the parks. Roughly 25.7% of the population is under the age of 18. That’s over a quarter of the city still in their formative years.
This youth creates a specific kind of energy. It’s why you see so much investment in places like Elgin Community College, which awarded over 2,100 degrees last year alone. The city is a pipeline for the next generation of the Illinois workforce.
On the flip side, the senior population (65 and over) sits at 12.8%. It's a healthy balance. You have the "Old Elgin" families who have been here for four generations living alongside first-generation immigrants who just moved into a bungalow last year.
Housing and Living Arrangements
If you're looking at the demographics of Elgin IL to decide if you should move there, the housing stats are vital. It's an owner's town. 71.4% of housing units are owner-occupied. This creates a sense of stability you don't always find in high-density areas.

The average household size is about 2.89 people. Compare that to the Chicago metro average of 2.5, and you realize Elgin has bigger families. More kids, more multi-generational living. It’s common to see a household where three generations are sharing a roof, especially within the foreign-born community where 75% of those born abroad hail from Latin America.
Poverty is still a factor, though. About 8.9% of families live below the poverty line. It’s a reminder that while the median income is rising, the "two Elgins" phenomenon—wealthy west-side developments versus struggling older neighborhoods—is a real thing that local leaders are constantly navigating.
What This Means for the Future
Elgin isn't shrinking. While some Illinois cities are seeing a mass exodus, Elgin’s population has remained relatively stable, even showing slight projected growth of 0.7% heading into 2026.
It’s becoming a hub for "suburban-urban" living. You get the diversity and food of a city with the backyard and garage of the suburbs. For businesses, this means a workforce that is bilingual, young, and relatively affordable compared to the North Shore.
