📝 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 Knollwood'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; another city can have a different sequence or fewer supported layers because the source joins are not uniform.

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

1. Housing and income

How far does income reach against housing in Knollwood?

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.

The home-value-to-income reference sits in a middle range: the ACS median home value is 2.8 times median household income. The ACS poverty estimate is 6.8%, which keeps the citywide median from describing every household.

Compare the housing trade-off →

2. Comparison shortlist

Which cities make useful reference points for Knollwood?

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.

Within Illinois, the closest population matches are Minonk (1,909 residents, $62,000 income); Jerome (1,910 residents, $55,777 income); Jonesboro (1,912 residents, $58,309 income). Outside the state, the closest population matches in this dataset are Munising, MI (1,907 residents); Corralitos, CA (1,906 residents); Pineville, KY (1,906 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.

Question 3

What does the journey to work look like in Knollwood?

Driving alone is the largest reported mode at 66.1%. A reliable mean commute time is not available for this row, so the mode shares carry the comparison.

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.

At 2.8×, Knollwood sits in the affordable band: national rank #5,534 of 15,516 and #4,811 of 11,323micro cities (under 10,000). 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). This is not a mortgage payment estimate and does not include rates, taxes, insurance, or down payment.
