Indiana vs Illinois at a Glance
Indiana and Illinois share a border and have many economic and cultural connections, but they are not identical places to live.
Illinois is considerably larger by population. The U.S. Census Bureau estimates Illinois had about 12.72 million residents on July 1, 2025, compared with about 6.97 million in Indiana.
| Category | Indiana | Illinois |
|---|---|---|
| 2025 population | 6.97 million | 12.72 million |
| Median household income | $71,957 | $83,390 |
| Median owner-occupied home value | $218,200 | $263,300 |
| Median gross rent | $1,062 | $1,274 |
| 2024 Regional Price Parity | 93.3 | 98.8 |
| 2026 state income tax | 2.95% | 4.95% |
| Aug. 2026 unemployment | 3.3% | 4.7% |
Population, income, housing, and unemployment figures come from the Census Bureau and BLS; the regional price parity comes from BEA data; tax rates come from the respective state revenue departments.
Indiana vs Illinois: Cost of Living
Cost of living is one of the biggest reasons people search for an Indiana vs Illinois comparison.
The Bureau of Economic Analysis uses Regional Price Parities (RPPs) to compare price levels across states. An index of 100 represents the national price level.
For 2024, Indiana’s overall RPP was 93.329, while Illinois’ was 98.752. That means statewide prices were measured at different levels relative to the national average, with Indiana’s overall index lower.
Housing and Rent
Housing can create an especially noticeable difference.
According to Census QuickFacts, Indiana’s median value for owner-occupied housing units was $218,200, compared with $263,300 in Illinois. Median gross rent was $1,062 in Indiana and $1,274 in Illinois for 2020–2024.
However, statewide numbers should not be treated as a quote for every city.
A home in downtown Chicago, for example, is part of a very different housing market from a home in Fort Wayne or a smaller Indiana community. Likewise, suburban areas around Chicago can have very different prices from the city itself.
Tip: When comparing the two states for a move, compare specific cities and neighborhoods rather than relying only on statewide averages.
Taxes in Indiana vs Illinois
Taxes are another major difference between Indiana and Illinois.
State Income Tax
For the 2026 tax year, Indiana’s individual adjusted gross income tax rate is 2.95%. Indiana also has county income taxes, so the state rate does not represent every income-tax obligation a resident may face.
Illinois has a 4.95% individual income tax rate.
This means the headline state income-tax rate is lower in Indiana.
Sales Tax
The comparison changes when you look at sales taxes.
As of July 1, 2026, Indiana has a 7% statewide sales tax with no local sales tax layered on top at the state level. Illinois has a 6.25% state sales tax, plus an average local rate of about 2.73%, producing an average combined rate of 8.98%.
Illinois also changed its treatment of qualifying food purchases in 2026, eliminating its 1% state sales tax on food while local jurisdictions may still impose local taxes.
Your total tax burden depends on more than one tax rate. Income, property, sales, local taxes, deductions, credits, and where you live can all affect the final result.
Jobs and Income
The two states have substantial economies, but their employment landscapes are different.
Illinois has a larger population and a larger overall employment base. Census data lists more than 5.66 million jobs in Illinois employer establishments in 2023, compared with about 2.92 million in Indiana.
Household Income
Illinois also has the higher statewide median household income in the latest Census figures:
- Indiana: $71,957
- Illinois: $83,390
These figures are inflation-adjusted to 2024 dollars and cover 2020–2024.
A higher statewide median income does not automatically mean an individual worker will earn more in Illinois. Pay varies considerably by occupation, industry, employer, and metropolitan area.
Employment and Unemployment
BLS data for August 2026 reported seasonally adjusted unemployment of 3.3% in Indiana and 4.7% in Illinois.
These figures describe the labor market at a particular point in time and can change from month to month.
Major employment opportunities are also concentrated differently. Illinois has the enormous Chicago metropolitan economy, while Indiana has major employment centers including Indianapolis and other cities across the state.
Lifestyle and Daily Life
Cities and Urban Living
One of the clearest lifestyle differences is the scale of the largest cities.
Illinois includes Chicago, one of the country’s largest metropolitan centers. Indiana’s largest city is Indianapolis, which offers a substantial urban economy but a different scale and metropolitan environment.
Illinois also has cities such as Springfield, Rockford, Peoria, and Champaign, while Indiana includes Fort Wayne, Evansville, South Bend, Bloomington, and others.
This gives both states a mix of urban, suburban, and smaller-community lifestyles.
Transportation and Commuting
Location matters greatly when transportation is part of the decision.
The Census Bureau reports an average commute time of 24.1 minutes in Indiana and 27.8 minutes in Illinois for workers age 16 and older, based on 2020–2024 data.
Chicago and its surrounding suburbs also have extensive public transportation options compared with many smaller communities.
For someone working in Chicago but considering housing in Northwest Indiana, the state boundary may have less practical importance than the actual commute, train access, tolls, and workplace location.
Geography and Population Density
Illinois has a larger land area and population, while Indiana is smaller in both respects.
Census data places Indiana’s 2020 population density at about 189 people per square mile, compared with about 231 people per square mile in Illinois.
That does not mean every part of Illinois is more crowded. Both states contain large rural areas.
Indiana vs Illinois for Moving
If you’re deciding where to live, the most useful approach is to match the state to your specific circumstances.
Reasons Someone May Prefer Indiana
Indiana may appeal to people who prioritize:
- Lower statewide housing costs
- A lower state individual income-tax rate
- A lower overall 2024 regional price parity
- Access to Indianapolis and other growing employment centers
- Living near Chicago while being outside Illinois
Reasons Someone May Prefer Illinois
Illinois may appeal to people who prioritize:
- Access to Chicago’s large metropolitan economy
- Higher statewide median household income
- Large urban and suburban communities
- Extensive transportation options in the Chicago region
- A wider range of large-city employment and cultural opportunities
Illinois’ higher median household income is documented by the Census Bureau, while the exact opportunities available to an individual depend on occupation and location.
The Importance of Choosing the Right City
This is perhaps the most important point in an Indiana vs Illinois comparison.
Comparing Indiana vs Illinois is useful for understanding state-level taxes and general economic conditions, but moving decisions are usually made at the city or metropolitan level.
For example:
Indianapolis vs Chicago is a different comparison from Fort Wayne vs Rockford or Crown Point vs a Chicago suburb.
The right comparison should include:
- Housing price or rent
- Salary for your specific job
- Commute time
- Income and local taxes
- Transportation costs
- School options if relevant
- Neighborhood characteristics
- Access to family, work, and services
Indiana vs Illinois: Which Differences Matter Most?
There isn’t one answer that applies to everyone.
If your main concern is state income tax and statewide price levels, Indiana’s lower individual income-tax rate and lower 2024 RPP are important factors.
If your priority is access to a major metropolitan economy, Illinois-particularly the Chicago area-offers a much larger urban environment.
If you’re focused on housing, statewide Census figures show lower median home values and rents in Indiana, although individual markets can differ dramatically.
If you’re comparing jobs, look at your specific occupation and city instead of using statewide unemployment or income as the only measure.
