📝 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 Port Jefferson'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 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 Port Jefferson, city-specific coverage includes matched public-school count, annual population history, commute-mode shares, local building permits. No matched row is reported here for 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

Which cities make useful reference points for Port Jefferson?

Within New York, the closest population matches are New Paltz (8,028 residents, $59,375 income); Lake Carmel (8,090 residents, $121,402 income); Congers (7,923 residents, $141,413 income). Outside the state, the closest population matches in this dataset are Wilmington Manor, DE (8,030 residents); Oak Brook, IL (8,028 residents); Juana Díaz zona urbana, PR (8,031 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.

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.

Open a side-by-side comparison →

Question 2

How far does income reach against housing in Port Jefferson?

The home-value-to-income reference is comparatively stretched: the ACS median home value is 4.4 times median household income. The ACS poverty estimate is 0.9%, which keeps the citywide median from describing every household.

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.

Compare the housing trade-off →

3. Population change

Is Port Jefferson growing, shrinking, or holding steady?

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.

Census PEP estimates show the population grew by +335 residents from 2020 to 2025, a +4.2% change. Separately, Census BPS recorded 36 housing units authorized in 2024. PEP and ACS are different Census series, so the trend is kept separate from the headline ACS population.

See the national growth ranking →

Question 4

What does the education layer cover for Port Jefferson?

The NCES join finds 3 public schools within the city match. 69.0% 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.

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.

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 Port Jefferson?

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.

Driving alone is the largest reported mode at 72.8%. A reliable mean commute time is not available for this row, so the mode shares carry the comparison.
