25,747 residents. Safety, jobs, income, housing cost, climate and natural-hazard risk for Plymouth County, IA.

Several figures AreaProfile publishes are measured by county and nowhere finer — death rates by intent among them. On this page those describe the geography they are printed on, which is not true of the city and ZIP pages that inherit them.

Each point is a separate five-year estimate, most recently $83,251 in the 2024 ACS 5-Year. Consecutive releases share four years of sample, so AreaProfile shows them as a record of successive estimates and does not compute a year-over-year change from them.

29.2% of students here are eligible for free or reduced-price lunch. That describes the circumstances families arrive with rather than how the schools perform, which is why AreaProfile shows it and does not score it.

Public schools only, from the NCES Common Core of Data. Schools are placed by ZIP code, so this is which schools are in this place rather than which one a particular address is zoned for — district boundaries do not follow municipal ones, and enrollment zones change. Fully virtual schools are excluded: they enroll students from across the state while reporting one administrative address, and counting them here would describe a school population this place does not have. The assessment covers grades 3 through 8, so a high school shows no proficiency figure — a dash in those columns means the test was not given at that school, not that it performed badly. Proficiency is measured against Iowa’s own standard, so it compares cleanly within the state and only broadly against other states; AreaProfile therefore ranks it within state. The directory is current, while the proficiency figures are from the last school year with national coverage before the pandemic interrupted testing.

Housing & affordability

How it’s calculated →

Median rent of $910 takes 13% of median household income, below the 30% threshold at which a household is considered cost-burdened.

A median home costs 2.7 times median household income here, close to the historic benchmark for an affordable market.

Both affordability measures come from the same ACS release as the income they are compared with, so the comparison is like for like. They describe housing cost against local earnings and are not a cost-of-living index — transport, groceries, healthcare, insurance and taxes are not included, and a place can look affordable here and still be expensive to live in for reasons this does not capture.

Permitting is decreasing, measured from 2022 to 2025.

An AreaProfile calculation combining permit volume per resident, its direction over one and three years, population change and employment growth. Permit volume alone is not the measure.

Population has grown 1% since 2020, reaching 25,825 in 2024.

Permitting has turned downward after moving the other way the year before.

At 3.5 permitted units per 1,000 residents, building activity is above the median for measured US locations.

Low or minimal exposure: landslide, ice storm, inland flooding, strong wind, earthquake.

Hazard ratings are AreaProfile calculations derived from the FEMA National Risk Index v1.20.0 (December 2025). FEMA National Risk Index county record. FEMA does not endorse this presentation. Higher physical resilience means lower exposure.

These are deaths, not offences — they say nothing about burglary, theft or assault.

Plymouth County records 0.0 homicide deaths per 100,000 residents a year, lower than most counties measured. The CDC does not publish this below county level.

Firearm deaths of all intents run at 8.8 per 100,000 — more than the homicide rate, because nationally most firearm deaths are suicides.

Drug overdose deaths run at 8.0 per 100,000 residents in Plymouth County.

Firearm deaths count every intent together, and nationally the majority are suicides rather than homicides. The two columns overlap and should not be added.

Age-adjusted rates from provisional death certificate records, published by the CDC for Plymouth County as a whole — these rates are not published below county level. A county can hold both a dense city centre and a suburb whose experience of it is nothing alike, so this describes the county around Plymouth County rather than Plymouth County itself. That is why AreaProfile shows these figures and does not put them in the Area Score. Where fewer than ten deaths were recorded the count is suppressed at source, and a rate built on single figures moves sharply between releases. What this measure has that reported crime does not: a death certificate is filed whether or not the local police agency submitted a return that year, so the figures stay comparable between places and over time.

What this profile does not cover

Three things people look for are missing from every AreaProfile page, and each is missing for a reason rather than by oversight. The Area Score is calculated without them and the weighting is documented on the methodology page.

Reported crime
Offences reported to police are published by department rather than by town, and only where a department reported every month of the year. No municipal department reports for this place — many smaller communities are policed by the county — so there is no figure to show. A partial year is never scaled up to look complete, and arrest counts or news volume are never substituted for it.
Taxes
Taxes are not published: no source covers them nationally with a method open enough to check. Cost of living now is — the index above is the Bureau of Economic Analysis price parity for this area — but it is a price level for all consumption rather than a budget for a household, its spread is driven mostly by housing, and it excludes taxes. Housing affordability is computed separately from rent, price and income, because that answers a narrower and more actionable question. Nothing here is individualised tax advice.
Anything about a specific address
Every figure describes an area, not a street or a house. School attendance zones, insurance pricing and the character of a neighbourhood all vary within the places measured here.
