📝 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: Eureka, SD
946 people live in Eureka, South Dakota - a small town by U.S. Census Bureau ACS 2023 estimates. Eureka households earn a median of $34,167 annually, in the lower quartile of U.S. cities for household income, with a poverty rate of 14.5%. Eureka's housing stock carries a median value of $69,800, and the median resident age is 58.7 years. 20.3% of adults here have a bachelor's degree or higher; 49.5% of working-age residents are in the labor force.
Housing supply pressure shows in Census Building Permit Survey data: 4 residential units were authorized in 2024 (Low Activity). NOAA puts Eureka's yearly average temperature at 41.8°F with 20.3 inches of precipitation per year and 44.3 inches of snowfall.
Living costs in South Dakota run below the national norm: the state registers 88.6 on a 100-equals-national-average index (Well Below Average) per BEA Regional Price Parities 2024. HUD Fair Market Rent for a typical two-bedroom in this state is $990 per month. Statewide, average monthly utility bills in South Dakota run around $200, per EIA 2023 residential energy data. Natural-hazard exposure scores 26.8 out of 100 on FEMA's National Risk Index (Very Low).
A decision-led reading path
Useful questions to ask of Eureka'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 within-city variation to climate and hazard context to comparison shortlist to schools and households to housing and income to work and mobility; another city can have a different sequence or fewer supported layers because the source joins are not uniform.
For Eureka, city-specific coverage includes matched public-school count, annual population history, within-city Census tract profiles, commute-mode shares, local building permits.
No matched row is reported here for FBI reported-crime rates; the page leaves those layers out instead of substituting a statewide or national value.
Question 1
Is Eureka growing, shrinking, or holding steady?
Census PEP estimates show the population declined by -32 residents from 2020 to 2025, a -4.0% change. Separately, Census BPS recorded 4 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.
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.
The two sources should not be blended into one comfort or safety score. Use the climate values for baseline conditions and the risk index as a prompt to inspect specific hazards, insurance, and local emergency guidance for a particular address.
NOAA normals put the annual mean temperature at 41.8°F, with 20.3 inches of precipitation and 44.3 inches of annual snowfall. FEMA's state-averaged National Risk Index score for South Dakota is 26.8 out of 100. Climate normals describe long-run weather; the FEMA score on PlainCities is a state average of county NRI inputs and combines hazards, exposure, vulnerability, and resilience.
Which cities make useful reference points for Eureka?
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 South Dakota, the closest population matches are Piedmont (956 residents, $52,730 income); Lake Andes (934 residents, $45,714 income); Valley Springs (967 residents, $97,031 income). Outside the state, the closest population matches in this dataset are Ehrenberg, AZ (946 residents); McNary, AZ (946 residents); Victor, IA (946 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.
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 Eureka?
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 3 public schools within the city match. 20.3% 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 far does income reach against housing in Eureka?
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 2.0 times median household income. The ACS poverty estimate is 14.5%, which keeps the citywide median from describing every household.

What does the journey to work look like in Eureka?
Driving alone is the largest reported mode at 82.8%. 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.

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).

Monthly Utility Costs
South Dakota statewide monthly utility average (EIA 2023): $200
EIA 2023 residential energy data puts average monthly utilities across South Dakota at $200 (electricity about $95 , water and sewer about $40 ).
These are South Dakota statewide averages, not a meter reading for Eureka. Actual bills vary by home size, usage, and local rates. Source: U.S. Energy Information Administration (EIA) 2023.
Living Costs & Risk
South Dakota's BEA cost-of-living index is 88.6 (Well Below Average; US average = 100, RPP 2024). HUD Fair Market Rent for a typical two-bedroom in the county around Eureka is $990/mo. FEMA's National Risk Index, averaged to South Dakota statewide on PlainCities, rates natural-hazard exposure at 26.8 / 100 (Very Low).
Cost/risk geography note
Cost of living is a South Dakota statewide BEA average; rent is a county-level HUD Fair Market Rent for the county Eureka sits in; the FEMA hazard score shown here is a statewide average of county NRI inputs, not a parcel-level reading.
