📝 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.

Statewide, HUD pegs Fair Market Rent for a two-bedroom unit at $1,063 monthly. EIA 2023 residential energy data puts Illinois's average monthly utility costs around $240 (state average). The average commute for Markham workers runs 30.4 minutes, with 62.0% driving alone and 11.0% working from home. On FEMA's National Risk Index, this area rates 54.5 out of 100 for natural-hazard exposure (Low).

A decision-led reading path

Useful questions to ask of Markham'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 comparison shortlist to work and mobility to housing and income 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 Markham, city-specific coverage includes annual population history, commute-mode shares, matched public-school count, local building permits. 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.

1. Comparison shortlist

Which cities make useful reference points for Markham?

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 Schiller Park (11,454 residents, $67,473 income); Pontiac (11,483 residents, $59,579 income); River Forest (11,489 residents, $148,711 income). Outside the state, the closest population matches in this dataset are Home Gardens, CA (11,430 residents); Winton, CA (11,429 residents); Ridgefield, NJ (11,439 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 2

What does the journey to work look like in Markham?

Driving alone is the largest reported mode at 62.0%. The reported mean trip to work is 30.4 minutes.

Mode share answers how workers usually travel; it does not measure congestion, reliability, distance to a particular job, or the quality of transit service. No single mode completely explains the work trip here. The mix is more useful than a one-number commute grade, especially when comparing places where transit, walking, and remote work divide the non-driving share differently.

Compare commute patterns →

3. Housing and income

How far does income reach against housing in Markham?

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.

The home-value-to-income reference is relatively compact: the ACS median home value is 2.3 times median household income. The ACS poverty estimate is 19.8%, which keeps the citywide median from describing every household.

Compare the housing trade-off →

Question 4

Is Markham growing, shrinking, or holding steady?

Census PEP estimates show the population declined by -345 residents from 2020 to 2025, a -3.0% change. Separately, Census BPS recorded 0 housing units authorized in 2024. PEP and ACS are different Census series, so the trend is kept separate from the headline ACS population.

Recent estimates point downward. A falling count can reflect migration, household size, annexation boundaries, or estimation noise, so it is a prompt to inspect the full series rather than a claim about local economic health.

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.

Schools and households

What does the education layer cover for Markham?

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 5 public schools within the city match. 15.6% 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.

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.
