📝 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 St. Marys'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 within-city variation to population change to work and mobility; another city can have a different sequence or fewer supported layers because the source joins are not uniform.

For St. Marys, city-specific coverage includes within-city Census tract profiles, local building permits, annual population history, commute-mode shares. No matched row is reported here for 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 St. Marys?

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 2.7 times median household income. The ACS poverty estimate is 3.8%, which keeps the citywide median from describing every household.

Compare the housing trade-off →

2. Comparison shortlist

Which cities make useful reference points for St. Marys?

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 Kansas, the closest population matches are South Hutchinson (2,826 residents, $42,221 income); Osage City (2,837 residents, $63,393 income); Galena (2,752 residents, $39,968 income). Outside the state, the closest population matches in this dataset are Clinton, MI (2,795 residents); Crewe, VA (2,795 residents); Fairbanks Ranch, CA (2,794 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 can 2 Census tracts reveal inside St. Marys?

PlainCities matches 2 Census tracts to this city.

That layer breaks the citywide income, rent, and home-value medians into smaller Census geographies, which can reveal differences that one municipal median necessarily hides. A tract is a statistical area, not a locally defined neighborhood or a promise about conditions on a particular block. Start with the city profile for the broad comparison, then use the tract layer to test whether the same housing and income pattern is consistent across the city. Large within-city spreads are a reason to avoid treating any citywide median as a universal resident experience.

Explore St. Marys's tract profiles →

Question 4

Is St. Marys growing, shrinking, or holding steady?

Census PEP estimates show the population grew by +32 residents from 2020 to 2025, a +1.2% change. Separately, Census BPS recorded 3 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 upward. Growth can increase housing demand and service needs, but the permit record must move in the same direction before calling it a supply response; the two series measure different things.

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.

Work and mobility

What does the journey to work look like in St. Marys?

Driving alone is the largest reported mode at 70.9%. 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. 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.

At 2.7×, St. Marys sits in the affordable band: national rank #5,238 of 15,516 and #4,572 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.
