📝 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 Seabrook Island'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 work and mobility to housing and income to comparison shortlist to population change; another city can have a different sequence or fewer supported layers because the source joins are not uniform.
For Seabrook Island, city-specific coverage includes annual population history, commute-mode shares.
No matched row is reported here for matched public-school count, local building permits, FBI reported-crime rates, within-city Census tract profiles; the page leaves those layers out instead of substituting a statewide or national value.
Question 1
What does the journey to work look like in Seabrook Island?
Driving alone is the largest reported mode at 48.3%. 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.
How far does income reach against housing in Seabrook Island?
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. Housing value is high relative to the citywide income median. That flags a question for comparison, not a verdict: tenure, household composition, financing costs, and the age of the ACS estimate can all change what a resident actually pays.
The home-value-to-income reference is comparatively stretched: the ACS median home value is 7.2 times median household income. The ACS poverty estimate is 1.0%, which keeps the citywide median from describing every household.
Which cities make useful reference points for Seabrook Island?
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 Carolina, the closest population matches are Sullivan's Island (2,127 residents, $179,614 income); Timmonsville (2,153 residents, $32,736 income); Blacksburg (2,158 residents, $33,500 income). Outside the state, the closest population matches in this dataset are Collierville, CA (2,107 residents); Albion, IL (2,107 residents); Long Valley, NJ (2,107 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.
Is Seabrook Island growing, shrinking, or holding steady?
Census PEP estimates show the population grew by +116 residents from 2020 to 2025, a +5.6% change. No comparable local building-permit series is available here, so population change should not be read as a housing-supply measure. 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.

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).
