📝 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 Waipahu'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 work and mobility to comparison shortlist to housing and income; another city can have a different sequence or fewer supported layers because the source joins are not uniform.

For Waipahu, city-specific coverage includes commute-mode shares, matched public-school count. No matched row is reported here for FBI reported-crime rates, within-city Census tract profiles, local building permits, annual population history; the page leaves those layers out instead of substituting a statewide or national value.

1. Schools and households

What does the education layer cover for Waipahu?

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 9 public schools within the city match. 18.6% 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 →

Question 2

What does the journey to work look like in Waipahu?

Driving alone is the largest reported mode at 59.6%. The reported mean trip to work is 30.8 minutes.

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.

3. Comparison shortlist

Which cities make useful reference points for Waipahu?

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 Hawaii, the closest population matches are Kailua CDP (Honolulu County) (39,762 residents, $146,615 income); Kaneohe (35,945 residents, $124,632 income); Pearl (45,079 residents, $114,682 income). Outside the state, the closest population matches in this dataset are Duncanville, TX (39,879 residents); Hobbs, NM (39,887 residents); Wausau, WI (39,893 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.

Open a side-by-side comparison →

4. Housing and income

How far does income reach against housing in Waipahu?

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 8.5 times median household income. The ACS poverty estimate is 10.1%, which keeps the citywide median from describing every household.

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). This is not a mortgage payment estimate and does not include rates, taxes, insurance, or down payment.
