📝 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: Grayslake, IL

Illinois's Grayslake is a small city, with 20,707 residents per the latest Census Bureau ACS figures. Grayslake households earn a median of $113,697 annually, placing it in the top quartile of U.S. cities for household income, with a poverty rate of 4.1%. Typical homes in Grayslake are valued around $293,900, and the median resident age is 35.9 years. 59.1% of adults here have a bachelor's degree or higher; 69.4% of working-age residents are in the labor force.

The Census Building Permit Survey recorded 8 residential units authorized here in 2024 (Building Boom), up 700% from five years earlier. Grayslake reports a comparatively low crime rate: the FBI's Uniform Crime Reporting program logs 706.7 total incidents per 100,000 residents here, below the national average (agency reporting is voluntary, so this measures reporting activity, not a definitive danger score).

Illinois tracks close to the national cost-of-living baseline: BEA Regional Price Parities 2024 puts Illinois at 100.0 on a 100-equals-national-average scale (Near Average). Statewide, HUD pegs Fair Market Rent for a two-bedroom unit at $1,063 monthly. Statewide, average monthly utility bills in Illinois run around $240, per EIA 2023 residential energy data. 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 Grayslake'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 reported crime to schools and households to population change 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 Grayslake, city-specific coverage includes local building permits, commute-mode shares, annual population history, FBI reported-crime rates, matched public-school count. 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. Housing and income

How far does income reach against housing in Grayslake?

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 2.6 times median household income. The ACS poverty estimate is 4.1%, which keeps the citywide median from describing every household.

Compare the housing trade-off →

Question 2

What can the FBI record say about safety in Grayslake?

The joined FBI UCR record reports 706.7 violent and property crimes per 100,000 residents, below the 2280.5 national reference used here. The difference is 69% lower in arithmetic terms, but agency participation is voluntary and reporting completeness varies.

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.

Review the safety ranking method →

3. Schools and households

What does the education layer cover for Grayslake?

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.

The NCES join finds 7 public schools within the city match. 59.1% 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.

See how the family ranking is built →

4. Comparison shortlist

Which cities make useful reference points for Grayslake?

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.

Within Illinois, the closest population matches are East Moline (20,837 residents, $63,328 income); Park Forest (20,898 residents, $62,305 income); Libertyville (20,493 residents, $162,270 income). Outside the state, the closest population matches in this dataset are Montrose, CO (20,703 residents); Wade Hampton, SC (20,703 residents); Lockport, NY (20,699 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.

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 Grayslake growing, shrinking, or holding steady?

Census PEP estimates show the population declined by -84 residents from 2020 to 2025, a -0.4% change. Separately, Census BPS recorded 8 housing units authorized in 2024. PEP and ACS are different Census series, so the trend is kept separate from the headline ACS population.

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.

Work and mobility

What does the journey to work look like in Grayslake?

Driving alone is the largest reported mode at 70.2%. 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.

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).
