What land sells for in Hancock County

Carthage has fewer than 10 clean land sales of its own of any one size in 36 months, so these are Hancock County's.

The middle half (25th to 75th percentile) and the median of arm's-length single-parcel land sales. Each size uses its own months (the shortest of 12, 24 or 36 that holds enough sales), so the sizes' counts need not add up to another figure on this page.

Recorded flood claims in Carthage

FEMA counts claims on buildings with NFIP flood insurance, so land without an insured building never shows here. Claims counted from 1978 to Sep 2026.

Counted in the 1 census block group that lies mostly inside Carthage, so the edges may reach past the town line.

Storm history

Hurricanes and tropical storms: the National Hurricane Center's final storm tracks for the 1950–2025 seasons. A storm counts when its center came within 50 miles of Hancock County's boundary. NHC records a storm's position every six hours; the path between those points is filled in with straight steps every ten minutes. A storm counts as a hurricane if it was one (winds of 74 mph or more) while within 50 miles, otherwise as a tropical storm (39 mph or more; subtropical storms included). A storm that had already lost its tropical status is not counted. A storm's status (hurricane, tropical storm or neither) holds until NHC's next position records a change. The category is the Saffir-Simpson category at the storm's highest wind within 50 miles.

Tornadoes: the Storm Prediction Center's tornado records, 1950–2025. Each tornado counts once for a county when SPC lists that county for it or its recorded path (a straight line from touchdown to lift-off) crosses the county. Ratings use the Fujita scale (F) before February 2007 and the Enhanced Fujita scale (EF) since; tornadoes with no rating are left out of the rating figures.

These are counts of past storms, not a forecast. They are a different measure from federal disaster declarations, which name every county a storm affected, wherever its center went.

Home value trend in Hancock County

This tracks home values, not land values. Land buyers read it as a sign of demand nearby: where homes gain value, builders and buyers follow. A vacant lot can move differently.

How: the change in FHFA's annual county index from 2020 and 2024 to 2025, rounded. The index follows repeat sales and refinance appraisals of the same single-family homes with Fannie Mae or Freddie Mac mortgages. It is in today's dollars, not adjusted for inflation, and FHFA calls these local indexes developmental. Where FHFA's sample is too small it publishes no figure, and none prints here.

Source: FHFA House Price Index, all-transactions, annual county index, 2025, last updated March 31, 2026. Method: Bogin, Doerner and Larson, “Local House Price Dynamics: New Indices and Stylized Facts”, FHFA Working Paper 16-01.

FHFA publishes no index for Carthage itself; this is Hancock County's, which includes it.

Property tax in Carthage

This is an area figure, not any one property's bill. A parcel's own tax depends on its taxable value, its exemptions and the taxing districts it sits in; parcel pages estimate that separately where the county publishes what is needed.

How: the Census place's median yearly property-tax bill divided by its median home value, both for owner-occupied homes (about 785 here) as owners report them in the Census Bureau's American Community Survey, 2020–2024. Owners estimate their home's value, and the survey has a margin of error; we show the figure only where the area has at least 250 owner-occupied homes and the margin is narrow. Median bill $1,960; median home value $112,900.

Counted for the Census place of Carthage (inside its limits or, for an unincorporated place, its Census boundary).

Development in Carthage

Counted inside the Census place boundary of Carthage city. Counted from USGS Annual NLCD land cover (2015, 2020 and 2025; 30 m squares on a 240 m grid, so edges are approximate). A square counts when it was forest, shrub, grassland, pasture, cropland or wetland in the start year and developed in 2025 (NLCD's developed classes, from lawns and roads to dense buildings). A satellite land-cover map misses some changes and mislabels a few; read it as a guide.

Climate and growing season

How: the frost dates are NOAA's 50% dates for 32°F: in half of the years 1991–2020 the last spring frost came before the first date, and in half the first fall frost came before the second (a date in January or February means the following winter). The growing season is NOAA's typical count of frost-free days, worked out year by year, so it can differ by a few days from the gap between the two dates (by more where frost is rare). Hot days, rain (with melted snow) and snowfall are 1991–2020 yearly averages. A town's station is the nearest NOAA station within 25 miles whose winter lows match the place's (within 5°F on the hardiness map's coldest-night figure), so a valley station is not used for a hilltop town. A low spot or a hillside on your own land can frost earlier or later.

Hardiness zone: the 2023 USDA map, which sorts places by the average coldest night of the year (1991–2020) into 10°F zones split into 5°F halves. It is read at the town's center (the Census Bureau's point for the place).

Health care near Carthage

Shortage designations: HRSA Health Professional Shortage Areas (primary care, mental health, dental), HRSA data, as of October 2026. Hospitals: CMS Care Compare hospital list (hospitals that report an emergency department), July 2026, located by the U.S. Census Bureau geocoder or, where it found no match, the USGS National Structures Dataset hospital point (a few hospitals neither finds are placed from their street address, or by their ZIP code's center only where that cannot change the count or the names shown); distances from the Census Bureau's center point of the county or town (2026 Gazetteer).

A Health Professional Shortage Area (HPSA) is the federal government's finding that an area, or a group of people in it, has too few primary-care doctors, dentists or mental-health providers for its population. A geographic designation covers everyone in the area; a population designation (for example “Low Income Population HPSA”) covers only that group. Some designations cover only some census tracts or county subdivisions (the “areas” counted). The designation types and statuses are HRSA's own words; a designation HRSA has proposed for withdrawal stays on its list until it is withdrawn, and only designations with status “Designated” are in the summary sentence. A designation is about how many providers there are, not the quality of care. Hospitals counted are acute-care, critical-access and rural emergency hospitals that report an emergency department to Medicare, under the name filed with Medicare or the hospital's current name; one Medicare listing can cover more than one campus. Veterans', military, children's and psychiatric hospitals are not counted, and no ratings are shown.

The shortage designations are Hancock County's; the hospital count is measured from the Census center point of Carthage.

Electricity

Service area: the territory polygon that holds the Census Bureau's center point of Carthage, from the HIFLD electric retail service territories (frozen 2025 copy) (U.S. DHS HIFLD / ORNL (HIFLD Open retired 2025-08-26; copy last edited 2025-08-21)); the federal map is approximate. The utility for a given address is the one whose territory it sits in: confirm with the utility. 2 other utilities report serving Hancock County to EIA.

Prices: average home price per kWh for each utility's own (bundled) home service in Illinois, home revenue divided by kWh sold, fixed monthly and fuel charges included; your bill depends on your use and rate plan. In Illinois many homes may buy power from a retail supplier instead; these prices are for homes on the utility's own supply. Source: U.S. Energy Information Administration, Form EIA-861, 2025: Sales to Ultimate Customers and Service Territory (utilities by county). Public domain.

Public schools

District figures: NCES Common Core of Data, school district file, school year 2024-25 (U.S. Department of Education, public domain). Students are the fall membership count; students per teacher divides them by full-time-equivalent classroom teachers. Regular public school districts only (not charter-only, state-run or regional service agencies).

Based in the town means the district's office address is in the town; the district's area can be larger or smaller than the town's.

These are districts, not attendance zones: a home is zoned for particular schools by its district. No ratings or test scores are shown.
