📝 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.

A decision-led reading path
Useful questions to ask of Williamsville'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 housing and income to comparison shortlist to work and mobility to population change to schools and households; another city can have a different sequence or fewer supported layers because the source joins are not uniform.
For Williamsville, city-specific coverage includes local building permits, annual population history, commute-mode shares, matched public-school count.
No matched row is reported here for within-city Census tract profiles, FBI reported-crime rates; the page leaves those layers out instead of substituting a statewide or national value.
Question 1
How far does income reach against housing in Williamsville?
The home-value-to-income reference is relatively compact: the ACS median home value is 1.8 times median household income. The ACS poverty estimate is 6.6%, 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. The ratio makes housing the clearest place to start this profile, but a low multiple can coexist with slow demand, older stock, or household-level hardship. Compare the home-value distribution and same-state peer table before treating it as an advantage.
Which cities make useful reference points for Williamsville?
Within Illinois, the closest population matches are Grayville (1,515 residents, $47,308 income); Mount Carroll (1,515 residents, $59,167 income); Mount Pulaski (1,513 residents, $70,175 income). Outside the state, the closest population matches in this dataset are Dunsmuir, CA (1,519 residents); Glendale, MS (1,519 residents); Lake Telemark, NJ (1,519 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.
What does the journey to work look like in Williamsville?
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 80.3%. A reliable mean commute time is not available for this row, so the mode shares carry the comparison.
Is Williamsville growing, shrinking, or holding steady?
The recent population line is broadly flat. That makes the composition of change more important than the headline count: housing turnover, household size, and age structure can shift even when the total barely moves.
Census PEP estimates show the population declined by -2 residents from 2020 to 2025, a -0.1% change. Separately, Census BPS recorded 1 housing units authorized in 2024. PEP and ACS are different Census series, so the trend is kept separate from the headline ACS population.
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.
Schools and households
What does the education layer cover for Williamsville?
The NCES join finds 2 public schools within the city match. 39.5% 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 matched institution count is small, so district boundaries and schools outside the city line may matter more than the municipal count suggests. Use the number as a coverage cue, then verify attendance zones with the district before making a household decision.

The multiple is comparatively compact among tracked cities, but a low ratio can still coexist with slow demand or household-level hardship.
How this ratio is calculated
Ratio = Census ACS 2023 median home value ÷ median household income for cities with both fields and population ≥ 1,000.
Rank 1 = lowest ratio (most compact). Bands match the fleet affordability thresholds used on guides (<3.0 / 3.0–5.0 / >5.0).
