📝 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.

FEMA's National Risk Index rates natural-hazard exposure at 69.4 out of 100 (Moderate).

A decision-led reading path

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

For Mamaroneck, city-specific coverage includes commute-mode shares, annual population history, matched public-school count, 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

What does the education layer cover for Mamaroneck?

The NCES join finds 6 public schools within the city match. 55.3% 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.

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.

See how the family ranking is built →

Question 2

How far does income reach against housing in Mamaroneck?

The home-value-to-income reference is comparatively stretched: the ACS median home value is 5.6 times median household income. The ACS poverty estimate is 3.2%, 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 →

Question 3

Which cities make useful reference points for Mamaroneck?

Within New York, the closest population matches are Plattsburgh (19,878 residents, $53,962 income); Lackawanna (19,779 residents, $48,185 income); East Northport (19,672 residents, $153,380 income). Outside the state, the closest population matches in this dataset are Altamont, OR (19,844 residents); Harvey, IL (19,831 residents); Universal City, TX (19,853 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 →

4. Work and mobility

What does the journey to work look like in Mamaroneck?

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.

Driving alone is the largest reported mode at 43.4%. The reported mean trip to work is 24.6 minutes.

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.

Population change

Is Mamaroneck growing, shrinking, or holding steady?

The recent population line is broadly flat. That makes the composition of change more important than the headline count: housing turnover, household size, and age structure can shift even when the total barely moves.

Census PEP estimates show the population declined by -175 residents from 2020 to 2025, a -0.9% change. Separately, Census BPS recorded 11 housing units authorized in 2024. PEP and ACS are different Census series, so the trend is kept separate from the headline ACS population.
