📝 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: Lake St. Louis, MO

Missouri's Lake St. Louis is a small town, with 17,538 residents per the latest Census Bureau ACS figures. Median household income here is $123,427 per year, placing it in the top quartile of U.S. cities for household income, with a poverty rate of 4.4%. Home values in Lake St. Louis run a median of $375,300, and the median resident age is 43.2 years. 49.5% of adults here have a bachelor's degree or higher; 64.2% of working-age residents are in the labor force.

In 2024, 29 residential building permits were authorized in Lake St. Louis (Construction Slowdown), down 84% from five years earlier, per Census BPS data. Lake St. Louis reports a comparatively low crime rate: the FBI's Uniform Crime Reporting program logs 662.0 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).

Living costs in Missouri run below the national norm: on BEA's 100-equals-national-average cost index, Missouri scores 90.8 (Well Below Average), per the 2024 Regional Price Parities release. HUD Fair Market Rent for a typical two-bedroom in this state is $972 per month. Statewide, average monthly utility bills in Missouri run around $219, per EIA 2023 residential energy data. FEMA's National Risk Index rates natural-hazard exposure at 50.6 out of 100 (Low).

A decision-led reading path

Useful questions to ask of Lake St. Louis'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 population change to schools and households to housing and income to work and mobility to reported crime to comparison shortlist; another city can have a different sequence or fewer supported layers because the source joins are not uniform.

For Lake St. Louis, city-specific coverage includes local building permits, commute-mode shares, matched public-school count, annual population history, 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.

Question 1

Is Lake St. Louis growing, shrinking, or holding steady?

Census PEP estimates show the population grew by +2,325 residents from 2020 to 2025, a +13.8% change. Separately, Census BPS recorded 29 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.

See the national growth ranking →

2. Schools and households

What does the education layer cover for Lake St. Louis?

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 1 public school within the city match. 49.5% 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 →

3. Housing and income

How far does income reach against housing in Lake St. Louis?

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 3.0 times median household income. The ACS poverty estimate is 4.4%, which keeps the citywide median from describing every household.

Compare the housing trade-off →

4. Comparison shortlist

Which cities make useful reference points for Lake St. Louis?

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 Missouri, the closest population matches are Kirksville (17,493 residents, $48,063 income); Clayton (17,282 residents, $128,898 income); Farmington (17,999 residents, $49,882 income). Outside the state, the closest population matches in this dataset are Eastlake, OH (17,538 residents); Graham, NC (17,537 residents); Morganton, NC (17,541 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.

Work and mobility

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

Driving alone is the largest reported mode at 75.3%. 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.

Reported crime

What can the FBI record say about safety in Lake St. Louis?

The joined FBI UCR record reports 662.0 violent and property crimes per 100,000 residents, below the 2280.5 national reference used here. The difference is 71% 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.

How does Lake St. Louis compare to other US cities?

Here's how Lake St. Louis stacks up against the full field of US cities (population 1,000+), computed live from Census and FBI data.

Household income 88% higher than other cities
Home value 75% pricier than other cities
Median rent 7% pricier than other cities
Safety 78% safer than other cities

"Safer than" reflects total crime rate from FBI UCR; the others use Census ACS estimates.

A national percentile can hide a lot of local variation: narrowed to Missouri alone, Lake St. Louis ranks #39 of 234 Missouri cities by lowest crime rate - a different, more locally useful comparison than stacking it against the entire country.
