📝 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 Plymouth'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 population change to comparison shortlist; another city can have a different sequence or fewer supported layers because the source joins are not uniform.
For Plymouth, city-specific coverage includes annual population history, local building permits, commute-mode shares.
No matched row is reported here for matched public-school count, 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 Plymouth?
Driving alone is the largest reported mode at 81.2%. 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.
How far does income reach against housing in Plymouth?
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 1.6 times median household income. The ACS poverty estimate is 4.5%, which keeps the citywide median from describing every household.
Is Plymouth growing, shrinking, or holding steady?
Census PEP estimates show the population declined by -15 residents from 2020 to 2025, a -3.9% change. Separately, Census BPS recorded 0 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.
Which cities make useful reference points for Plymouth?
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 Iowa, the closest population matches are Calamus (405 residents, $66,250 income); New Market (407 residents, $58,125 income); Riverdale (408 residents, $88,500 income). Outside the state, the closest population matches in this dataset are North Courtland, AL (405 residents); Tununak, AK (405 residents); Rock Point, AZ (405 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.

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).
