📝 How we sourced this

Population, income, and housing-cost figures come from the U.S. Census Bureau American Community Survey 5-year estimates (B-series tables). Crime data uses FBI UCR; climate uses NOAA Climate Normals; school counts come from NCES Common Core of Data; permits use the Census Building Permits Survey (BPS). See our methodology page for the full ETL pipeline and OMB / FIPS join keys.

Data Snapshot: Naperville, IL

Naperville is a mid-sized U.S. city in Illinois, home to 149,424 residents per U.S. Census Bureau ACS 2023 estimates. Median household income here is $150,937 per year, placing it in the top quartile of U.S. cities for household income, with a poverty rate of 3.0%.

Naperville reports a comparatively low crime rate: FBI UCR reporting places total crime at 967.3 incidents per 100,000 residents, below the national average (voluntary agency reporting, reflects reporting activity, not a definitive danger score).

Illinois tracks close to the national cost-of-living baseline: on BEA's 100-equals-national-average cost index, Illinois scores 100.0 (Near Average), per the 2024 Regional Price Parities release. Statewide, HUD pegs Fair Market Rent for a two-bedroom unit at $1,063 monthly. Monthly utility costs average around $240 across Illinois, per EIA 2023 residential energy estimates. Workers in Naperville report an average commute of 22.8 minutes, with 58.9% driving alone and 27.3% working from home. Natural-hazard exposure scores 54.5 out of 100 on FEMA's National Risk Index (Low).

A decision-led reading path

Useful questions to ask of Naperville's data

How this reading path is ordered

This is not a composite city score. It is a city-specific route through the available public records, ordered for this profile so the page starts with questions the joined data can actually answer. The route here runs from reported crime to work and mobility to comparison shortlist to schools and households to population change to housing and income; another city can have a different sequence or fewer supported layers because the source joins are not uniform.

For Naperville, city-specific coverage includes FBI reported-crime rates, commute-mode shares, annual population history, matched public-school count, local building permits. No matched row is reported here for within-city Census tract profiles; the page leaves those layers out instead of substituting a statewide or national value.

1. Reported crime

What can the FBI record say about safety in Naperville?

Treat this as a reporting-rate comparison, not a prediction of personal risk or a neighborhood-level safety grade. Tourism, daytime population, reporting practices, and variation inside the city are not adjusted away. The state rank and same-state peer table are the narrower comparisons available on this page.

The joined FBI UCR record reports 967.3 violent and property crimes per 100,000 residents, below the 2280.5 national reference used here. The difference is 58% lower in arithmetic terms, but agency participation is voluntary and reporting completeness varies.

Review the safety ranking method →

2. Work and mobility

What does the journey to work look like in Naperville?

Mode share answers how workers usually travel; it does not measure congestion, reliability, distance to a particular job, or the quality of transit service. Remote work has a visible role in the local pattern. That can reduce commute exposure for some workers, but it says nothing about job availability or broadband quality; read it alongside income and housing rather than as a stand-alone lifestyle score.

Driving alone is the largest reported mode at 58.9%. The reported mean trip to work is 22.8 minutes.

Compare commute patterns →

Question 3

Which cities make useful reference points for Naperville?

Within Illinois, the closest population matches are Joliet (149,785 residents, $88,026 income); Rockford (147,649 residents, $53,328 income); Aurora (179,867 residents, $90,109 income). Outside the state, the closest population matches in this dataset are Pasadena, TX (149,345 residents); Surprise, AZ (149,519 residents); Jackson, MS (149,827 residents). A third, income-matched reference set of 6 out-of-state cities sits in the income neighbourhood chart near the Place Dossier plate. These are mechanical peer sets, not claims that the places share a labor market, climate, culture, or metro context.

Use the in-state set to hold state policy and broad price conditions more nearly constant. Use the nationwide size set to ask whether cities with a similar resident count produce different housing, income, or commute outcomes. The income set is a third lens, deliberately separate from population matching. The nationwide peer panel below adds a fourth FBI UCR reporting-rate lens, not personal risk.

Open a side-by-side comparison →

Question 4

What does the education layer cover for Naperville?

The NCES join finds 41 public schools within the city match. 71.7% of adults age 25+ hold a bachelor's degree or higher in the ACS estimate. These measures answer different questions: the school count describes local institutions, while adult attainment describes residents and cannot be used as a school-quality rating.

The city has a broader matched school footprint, but count alone does not describe performance, capacity, program availability, or attendance boundaries. This profile deliberately avoids converting it into an unsupported family-friendliness score.

Other supported questions

Why these stay compact

These joined records add useful context, but they do not need another full-size panel. Each remains a separate measure with its own geography and source boundary.

Population change

Is Naperville growing, shrinking, or holding steady?

Recent estimates point upward. Growth can increase housing demand and service needs, but the permit record must move in the same direction before calling it a supply response; the two series measure different things.

Census PEP estimates show the population grew by +3,730 residents from 2020 to 2025, a +2.5% change. Separately, Census BPS recorded 369 housing units authorized in 2024. PEP and ACS are different Census series, so the trend is kept separate from the headline ACS population.

Housing and income

How far does income reach against housing in Naperville?

The home-value-to-income reference sits in a middle range: the ACS median home value is 3.4 times median household income. The ACS poverty estimate is 3.0%, which keeps the citywide median from describing every household.

This is a citywide price-to-income reference, not a mortgage-affordability test; it does not include interest rates, taxes, insurance, household size, or an individual buyer's down payment. Income and home value move within the same broad scale here. The useful next check is not a generic affordability label, but whether similar-size cities offer a materially different income, housing, or commute trade-off.
