📝 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: Assumption, IL
1,117 people live in Assumption, Illinois - a small town by U.S. Census Bureau ACS 2023 estimates. Median household income here is $55,764 per year, below the median for U.S. cities on this measure, with a poverty rate of 15.3%. Home values in Assumption run a median of $72,100, and the median resident age is 34.3 years. About 14.8% of adults hold a bachelor's degree or higher, while 58.6% of working-age residents are in the labor force.
The Census Building Permit Survey recorded 0 residential units authorized here in 2024 (No Permits). Assumption reports a comparatively low crime rate: per-100,000 total crime stands at 0.0 in FBI UCR data, below the national average (a voluntary reporting program, read this as reporting activity, not a definitive danger score).
Illinois tracks close to the national cost-of-living baseline: the state registers 100.0 on a 100-equals-national-average index (Near Average) per BEA Regional Price Parities 2024. 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). 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 Assumption'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 housing and income to population change to reported crime to schools and households to work and mobility; another city can have a different sequence or fewer supported layers because the source joins are not uniform.
For Assumption, city-specific coverage includes commute-mode shares, annual population history, local building permits, matched public-school count, FBI reported-crime rates.
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. Comparison shortlist
Which cities make useful reference points for Assumption?
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 Lovington (1,120 residents, $54,394 income); Bull Valley (1,121 residents, $185,417 income); East Hazel Crest (1,122 residents, $57,000 income). Outside the state, the closest population matches in this dataset are Baudette, MN (1,117 residents); Lake Shore, MN (1,117 residents); Cairo, NE (1,117 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.
How far does income reach against housing in Assumption?
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 1.3 times median household income. The ACS poverty estimate is 15.3%, which keeps the citywide median from describing every household.
Is Assumption growing, shrinking, or holding steady?
Census PEP estimates show the population declined by -36 residents from 2020 to 2025, a -3.1% 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.
What can the FBI record say about safety in Assumption?
The joined FBI UCR record reports 0.0 violent and property crimes per 100,000 residents, below the 2280.5 national reference used here. The difference is 100% 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.
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 Assumption?
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 NCES join finds 2 public schools within the city match. 14.8% 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.

What does the journey to work look like in Assumption?
Driving alone is the largest reported mode at 86.7%. 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. The profile is strongly car-oriented, so a relocation comparison should put trip distance, vehicle access, and household fuel costs ahead of a citywide commute average. The same-state peer links offer a more relevant benchmark than a national label.

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).

FEMA's National Risk Index, averaged to Illinois statewide on PlainCities, rates natural-hazard exposure at 54.5 / 100 (Low).
Cost/risk geography note
Cost of living is a Illinois statewide BEA average; rent is a county-level HUD Fair Market Rent for the county Assumption sits in; the FEMA hazard score shown here is a statewide average of county NRI inputs, not a parcel-level reading.
