Greene County

Greene County is located in west-central Illinois, along the Illinois River and west of Springfield, within the state’s Mississippi River watershed. Established in 1821 and named for Revolutionary War general Nathanael Greene, the county developed as an agricultural and river-oriented region, with small towns serving surrounding farm communities. Greene County is small in population (about 11,800 residents as of the 2020 U.S. Census), with low population density and a predominantly rural character. Its landscape includes broad croplands, wooded river bluffs, and floodplain areas associated with the Illinois River and its tributaries. The local economy is anchored by agriculture and related services, supplemented by government, education, and small-scale manufacturing and commerce in its towns. Cultural life reflects a Central Illinois rural tradition, with community institutions centered on schools, local government, and civic organizations. The county seat is Carrollton.

Greene County is in west-central Illinois along the Illinois River, with its county seat in Carrollton. For local government and planning resources, visit the Greene County official website.

Population Size

According to the U.S. Census Bureau’s QuickFacts for Greene County, Illinois, Greene County had an estimated population of 11,846 (most recent “Population estimates” figure shown on QuickFacts).

Age & Gender

County-level age distribution and sex composition (gender ratio) are published by the U.S. Census Bureau through the Greene County profile on data.census.gov (American Community Survey tables). A single definitive set of age-by-group percentages and a male/female ratio is not available from QuickFacts alone; the Census Bureau’s detailed ACS tables should be used for the county’s current age brackets and sex counts.

Racial & Ethnic Composition

According to the U.S. Census Bureau’s QuickFacts for Greene County, Illinois (Race and Hispanic Origin section), Greene County’s racial and ethnic composition is reported using Census categories (e.g., White; Black or African American; American Indian and Alaska Native; Asian; Native Hawaiian and Other Pacific Islander; Two or More Races; and Hispanic or Latino ethnicity). QuickFacts provides the county’s currently published percentages for these categories.

Household & Housing Data

According to the U.S. Census Bureau’s QuickFacts for Greene County, Illinois, county-level household and housing indicators are reported in the “Housing” and “Families & Living Arrangements” sections (including items such as number of households, persons per household, owner-occupied housing rate, median value of owner-occupied housing units, median gross rent, and total housing units). QuickFacts is the authoritative single-page Census Bureau summary for these household and housing figures.

Primary Source

The demographic statistics referenced above are compiled by the U.S. Census Bureau for Greene County at QuickFacts (Greene County, Illinois), with additional detail available via Greene County table searches on data.census.gov (ACS).

Greene County, Illinois is a largely rural county with low population density, which tends to increase last‑mile network costs and can constrain reliable home internet access, affecting routine digital communication such as email.

Direct county-level email usage rates are not typically published; email adoption is commonly inferred from proxy indicators like broadband subscriptions, device access, and age structure. The most comparable local measures come from the U.S. Census Bureau’s American Community Survey, including household broadband subscription and computer ownership, which track the practical ability to use web-based email services. Age composition also matters because older populations generally show lower rates of some digital service adoption; Greene County’s age distribution (ACS) provides context for potential barriers and slower uptake.

Gender distribution is available in ACS demographic profiles, but it is generally a weaker predictor of email access than broadband and age, so it is mainly used for population context rather than access diagnosis.

Connectivity constraints are reflected in rural coverage gaps and provider availability documented through the FCC National Broadband Map, and local planning context may appear on the Greene County government website.

Greene County is in west-central Illinois along the Illinois River, with a predominantly rural land use pattern, small population centers (including Carrollton), and low overall population density relative to metropolitan Illinois. These characteristics typically increase the per‑mile cost of cellular and backhaul infrastructure and can produce coverage gaps outside towns and along less-traveled roads, which directly affects network availability but does not by itself measure household adoption.

Key terms and scope (availability vs. adoption)

• Network availability (supply-side): Where mobile carriers report service (voice/LTE/5G) and where mapping programs show coverage. Availability does not indicate whether residents subscribe or use mobile service.
• Household adoption (demand-side): Whether households have mobile subscriptions, smartphones, or rely on cellular for internet access. Adoption is influenced by income, age, affordability, and perceived usefulness, in addition to coverage.

County-specific adoption metrics are limited; many widely used datasets report reliable estimates at the state level (Illinois) or for broader geographies rather than at the county level.

Mobile penetration / access indicators (where available)

County-level “mobile subscription” measurement limitations

• Publicly accessible, county-level statistics such as “mobile phone subscription rate” or “smartphone ownership rate” are generally not published in a single authoritative series for Greene County.
• The most commonly cited U.S. adoption measures come from national surveys that are not designed to produce stable county estimates. For baseline national and demographic smartphone ownership trends (not county-level), see Pew Research Center mobile fact sheet.

Proxy adoption indicators available from the U.S. Census (county-level)

While not a direct “mobile penetration” measure, the Census provides county data on internet subscription type, including cellular data plans:

• The U.S. Census Bureau’s American Community Survey (ACS) includes “Cellular data plan” as an internet subscription category and also identifies households with no internet subscription. These can be used as proxy indicators for mobile internet adoption at the household level, with known survey sampling limitations in small rural counties.
• County estimates can be retrieved via data.census.gov (ACS tables related to “Internet Subscriptions” and “Computer and Internet Use”).
• Methodology and definitions are documented by Census.gov ACS program materials.

Interpretation note: ACS “cellular data plan” reflects whether a household reports a cellular data plan used to access the internet; it does not indicate the quality of coverage or whether the plan is the household’s primary connection.

Mobile internet usage patterns (4G and 5G) and network availability

4G LTE availability

• LTE is the baseline mobile broadband technology across most of Illinois, including rural counties. County-specific coverage can be reviewed using federal broadband/mobile mapping:
  • The FCC National Broadband Map provides location-based views of mobile broadband availability by provider and technology, including 4G LTE and 5G. The FCC map is the primary public reference for reported coverage and is designed for availability, not adoption.
• In rural areas, LTE availability can vary substantially by road corridor, terrain/vegetation, tower density, and device band support; reported coverage areas can overstate real-world indoor performance. These are well-known measurement issues in mobile mapping; the FCC map is still the standard public source for provider-reported availability.

5G availability (and typical rural pattern)

• 5G availability in rural counties often appears first as low-band 5G overlays on existing LTE coverage, with more limited mid-band and minimal mmWave outside dense urban cores. Greene County’s 5G footprint depends on provider deployment choices and spectrum holdings, and must be verified through the FCC map by selecting technology layers and providers.
• The most defensible county statement is that 5G availability is provider- and location-specific, with broader availability in/near towns and along primary routes than in sparsely populated areas, as reflected in coverage layers on the FCC map. The FCC map provides the appropriate technology-by-location detail, while avoiding claims about actual take-up.

Actual mobile internet usage vs. availability

• County-level statistics on how many residents actually use 4G vs. 5G (share of traffic, handset attach rate) are not typically published by carriers at the county level.
• Household reliance on cellular for internet access can be approximated using ACS “cellular data plan” subscription reporting (adoption), but that does not separate 4G vs. 5G usage.

Common device types (smartphones vs. other devices)

County-level device-type data limitations

• Public, county-level distributions of smartphones vs. feature phones or handset models are not generally available from official sources.
• The ACS measures computer type (desktop/laptop/tablet) and internet subscription types, but it does not provide a direct county statistic for “smartphone ownership.” National benchmark device ownership patterns are available from Pew Research Center, but those are not county-specific.

Practical interpretation from available public metrics

• For Greene County, the most evidence-based approach is:
  • Use ACS subscription categories (including cellular data plan) as a proxy for households using mobile networks for internet access.
  • Use national/state device-ownership research (e.g., Pew) only for broad context, clearly separated from county claims.

Demographic and geographic factors influencing mobile usage and connectivity

Rural settlement pattern and tower economics (availability impact)

• Lower population density generally reduces the business case for dense tower placement and fiber backhaul, which can affect:
  • Outdoor coverage continuity
  • Indoor signal strength (especially at higher frequencies)
  • Peak-time capacity in areas served by fewer sites
• Greene County’s rural character and dispersed housing pattern are therefore most directly linked to availability and quality variability rather than directly measuring adoption.

Income, age, and education (adoption impact)

• Nationally, smartphone ownership and home broadband adoption correlate with income and age; lower-income households are more likely to be “mobile-only” for internet access. These relationships are documented at a general level by Pew Research Center and by ACS internet subscription measures on data.census.gov.
• Greene County-specific demographic context (age structure, income, education) is available through ACS profiles on data.census.gov. These variables can be used to interpret adoption patterns, but they do not provide direct smartphone counts.

Transportation corridors and river geography (availability impact)

• Greene County’s location along the Illinois River and its mix of river-adjacent lowlands and uplands can influence radio propagation locally (line-of-sight, vegetation, and placement constraints), but publicly accessible countywide engineering measurements are not typically available. The FCC availability map remains the defensible public reference for spatial coverage patterns.

Authoritative public sources for Greene County-focused connectivity review

• Mobile broadband availability (4G/5G by provider, location-based): FCC National Broadband Map
• Household internet subscription types (including cellular data plan) and demographics: data.census.gov and Census.gov ACS documentation
• State broadband planning context and programs (statewide, not county adoption): Illinois Department of Commerce and Economic Opportunity (DCEO) (includes broadband-related initiatives and materials)
• County context (government and geography references): Greene County, Illinois official website

Summary of what can be stated reliably for Greene County

• Availability: Location-specific 4G LTE and 5G availability can be reviewed using the FCC National Broadband Map; coverage is typically more continuous near towns and main routes than in sparsely populated areas, with performance varying by location and indoor/outdoor conditions.
• Adoption: County-level adoption can be proxied through ACS household internet subscription categories (including “cellular data plan”), but direct county smartphone penetration statistics are not generally available from official public sources.
• Devices: County-level smartphone vs. feature phone shares are not available in standard public datasets; national benchmark patterns exist but cannot be substituted for county estimates.
• Drivers: Rural settlement and infrastructure economics primarily affect availability; demographic factors captured in ACS data (income, age, education) are relevant to interpreting adoption, without providing direct device counts.

Greene County is a rural county in west‑central Illinois along the Illinois River, with Carrollton as the county seat and small communities such as White Hall and Roodhouse. Its economy is shaped largely by agriculture and local services, and its dispersed settlement pattern typically aligns with heavier reliance on mobile connectivity and community‑focused channels (local Facebook groups/pages) rather than dense, urban, in‑person networks.

User statistics (penetration / active use)

• Local, county-specific social media penetration figures are not published consistently in major public datasets. The most defensible approach is to use U.S. and Illinois rural benchmarks from large surveys and broadband availability context.
• Overall U.S. adult social media use: about 7 in 10 U.S. adults (≈69%) use social media, with adoption varying strongly by age. Source: Pew Research Center social media fact sheet.
• Rural vs. urban: Pew routinely finds lower adoption in rural areas than suburban/urban areas, largely tracking broadband access and age structure. Source: Pew Research Center Internet & Technology research.
• Connectivity context relevant to rural counties: broadband availability and adoption are key correlates of usage levels. National baseline reporting is available via FCC National Broadband Map (service availability) and related federal broadband adoption research.

Age group trends

Patterns in Greene County typically follow national age gradients seen across rural U.S. counties:

• Highest social media use: 18–29 and 30–49 adults lead adoption and frequency of use. Nationally, these groups are the most consistently “online throughout the day” across major platforms. Source: Pew Research Center social media fact sheet.
• Moderate use: 50–64 shows substantial participation, often concentrated on a smaller set of platforms (commonly Facebook).
• Lowest use: 65+ has the lowest overall social media adoption and tends to use fewer platforms, though Facebook remains a common entry point among older adults. Source: Pew Research Center social media fact sheet.

Gender breakdown

• Overall adult social media use is broadly similar by gender in national survey reporting, with platform-level differences more pronounced than overall adoption.
• Women are more likely than men to use certain platforms (notably Pinterest in many surveys), while men are more likely on some discussion/tech-forward platforms; however, in rural-county contexts the practical effect is often that Facebook remains the dominant cross-gender platform. Source: Pew Research Center social media fact sheet.

Most-used platforms (percentages)

County-level platform shares are generally not published; the following are widely cited U.S. adult usage benchmarks that align with observed rural patterns (Facebook dominance and strong YouTube reach):

• YouTube: ~83% of U.S. adults
• Facebook: ~68%
• Instagram: ~47%
• Pinterest: ~35%
• TikTok: ~33%
• LinkedIn: ~30%
• X (formerly Twitter): ~22%
• Snapchat: ~27%
  Source for platform usage rates: Pew Research Center social media fact sheet.

Implications for Greene County: In rural Illinois counties, Facebook and YouTube typically function as the primary “mass reach” platforms, while Instagram and TikTok skew younger and Snapchat is concentrated among teens/young adults.

Behavioral trends (engagement patterns / preferences)

• Community information utility: Rural counties commonly show heavier reliance on Facebook pages/groups for local news, school/sports updates, event calendars, and mutual-aid/community discussions. This reflects fewer local media options and higher value placed on community bulletin-board functions.
• Video as a universal format: YouTube’s high adoption supports how‑to, agriculture/home maintenance content, local sports highlights, and church/community programming consumption patterns.
• Age-driven platform segmentation:
  • Younger residents concentrate engagement on short-form video (TikTok/Instagram Reels/Snapchat) and direct messaging.
  • Middle-aged and older residents concentrate on Facebook for updates, photos, and community announcements.
    Source for age/platform segmentation patterns: Pew Research Center.
• Engagement frequency: Nationally, many users report being online multiple times per day, with the highest “near-constant” usage among younger adults—patterns that extend into rural areas as smartphone connectivity substitutes for proximity-based social interaction.

Greene County, Illinois maintains family and associate-related public records through the County Clerk, Circuit Clerk, and Recorder.

Vital records (birth and death) are administered locally by the Greene County Clerk, generally for certified copies and local registration functions, with statewide oversight through the Illinois Department of Public Health (IDPH) Vital Records. Marriage licenses and marriage records are also handled by the County Clerk. Adoption records are typically processed through the circuit court system; access is restricted and managed via the Greene County Circuit Clerk and applicable state procedures.

Property and related associate records (deeds, mortgages, liens, releases) are recorded by the Greene County Recorder. Court case files, including probate, guardianship, and civil matters, are maintained by the Circuit Clerk; statewide electronic case access is provided through Illinois Courts e-Access (coverage varies by case type and filing date).

Online access depends on the office and record type; many requests and searches are completed in person at the relevant office, with mail/phone request options commonly available. Privacy restrictions apply to many vital records (notably recent birth records) and to adoption files, while recorded land records are generally public. Fees, identification requirements, and redaction rules are set by the maintaining office and state law.

Types of records available

• Marriage records (licenses/returns/certificates): Marriage records in Greene County are created when a couple applies for a marriage license through the county clerk. The completed license is returned for recording after the ceremony, forming the official county marriage record.
• Divorce records (decrees/judgments): Divorce records are court case records maintained by the circuit court. The final Judgment for Dissolution of Marriage (often called a divorce decree) is part of the case file.
• Annulment records: Annulments are handled as court matters (a declaration that a marriage is invalid/void/voidable under Illinois law) and are maintained within circuit court case files. Final orders are recorded within the court record.

Where records are filed and how they can be accessed

• Marriage records
  • Filed/maintained by: Greene County Clerk (vital records function for marriages at the county level).
  • Access: Copies are typically obtained from the County Clerk’s office. Some older indexes and images may also be accessible through archival or genealogy platforms, depending on the time period and what has been digitized.
• Divorce and annulment records
  • Filed/maintained by: Greene County Circuit Clerk (court records for civil/domestic relations cases).
  • Access: Case records are accessed through the Circuit Clerk’s records request processes and, where available, public access terminals or online case lookup systems. Document-level access is subject to Illinois court rules on public access and confidentiality, and sealed or impounded filings are not publicly available.

Typical information included in these records

• Marriage license/record
  • Full names of the parties
  • Date and place of marriage (or intended place/date and then the recorded return)
  • Ages and/or dates of birth (varies by era and form)
  • Residences and places of birth (commonly present on applications in many periods)
  • Names of officiant and date of ceremony; officiant’s signature and the returned/recorded certificate portion

  • Court caption (case title), case number, filing date, and date of judgment
  • Names of the parties and findings/jurisdictional statements required by Illinois law
  • Disposition terms such as dissolution date, property allocation, maintenance (spousal support), and allocation of parental responsibilities/parenting time and child support when applicable
  • References to incorporated agreements or parenting plans, when filed
• Annulment order/judgment
  • Court caption and case number
  • Findings supporting invalidity/voidability under Illinois law
  • Order declaring the marriage invalid (and related determinations such as property issues or support, when applicable)

Privacy or legal restrictions

• Marriage records: Marriage records are generally treated as public records, though access to certain identifying details can be restricted in practice for privacy and fraud-prevention reasons, and certified copies are issued under county and state rules. Some older records may be fully open, while more recent records may be subject to stricter identification and issuance requirements for certified copies.
• Divorce and annulment court files: Many case docket entries and final judgments are public, but Illinois court rules and statutes restrict access to certain categories of information and filings. Common restrictions include:
  • Sealed/impounded records by court order (not publicly accessible)
  • Confidential information (such as Social Security numbers, certain financial account data, and other protected identifiers) subject to redaction and access limits under Illinois Supreme Court rules on privacy and public access
  • Cases involving minors and sensitive family matters may have additional confidentiality protections for specific documents or data elements
• Vital records administration: At the state level, marriage and divorce data are also reported for statistical and administrative purposes, but certified vital record copies are governed by Illinois vital records laws and administrative rules, with identity/eligibility requirements varying by record type and the nature of the copy requested (certified vs. informational).

Greene County is a largely rural county in west‑central Illinois along the Illinois River, with its county seat in Carrollton and small communities such as White Hall and Roodhouse. The county has an older-than-average age profile typical of many rural Midwest areas, modest population density, and a community context shaped by agriculture, small manufacturing and services, and commuting to nearby regional job centers. Population and baseline demographic context are commonly reported through the U.S. Census Bureau data portal (American Community Survey).

Education Indicators

Public schools (count and names)

Public K–12 education in Greene County is primarily provided through local districts serving Carrollton, White Hall/North Greene, and the Roodhouse area. A consolidated list of public schools and districts is available via the Illinois Report Card (search by county/district). Commonly listed schools serving Greene County include:

• Carrollton Unit School District: Carrollton Grade School; Carrollton High School
• North Greene Unit School District: North Greene Elementary School; North Greene Jr./Sr. High School
• Roodhouse area: public schooling has historically been provided through area unit districts that may serve multiple counties; the Illinois Report Card is the authoritative source for the current configuration and school roster.

Note: Countywide “number of public schools” varies by how schools are counted (attendance centers vs. program sites). The Illinois Report Card provides the most current official inventory by district.

Student–teacher ratios and graduation rates

• Student–teacher ratio: Reported at the district/school level through the Illinois Report Card rather than as a single countywide figure. Rural downstate districts frequently fall in the low-to-mid teens (students per teacher) as a general regional pattern; the county’s definitive ratios are school-specific.
• Graduation rates: Illinois publishes 4‑year high school cohort graduation rates by school/district on the Illinois Report Card. Greene County’s graduation rates are therefore best described at the district high school level (Carrollton HS; North Greene Jr./Sr. HS), and can vary year to year due to small cohort sizes.

Adult education levels

Adult educational attainment is reported through the American Community Survey on data.census.gov. Greene County generally reflects rural downstate Illinois patterns:

• A majority of adults have at least a high school diploma.
• The share with a bachelor’s degree or higher is typically below statewide averages (Illinois overall is substantially higher due to the Chicago metro area).
  Proxy note: When summarizing without pulling a single table value, the defensible statement is “high school completion is common; bachelor’s attainment is lower than the Illinois average,” consistent with ACS profiles for rural counties.

Notable programs (STEM, vocational, AP)

Program availability is district-specific and is typically documented in:

• Illinois Report Card “College and Career Readiness” indicators (including Advanced Placement participation where offered).
• District course catalogs and student handbooks. In rural unit districts, common offerings include:
• Career and Technical Education (CTE) pathways (e.g., agriculture, skilled trades, business/technology), sometimes supported through regional career centers or cooperative arrangements.
• Dual credit coursework partnerships (often with nearby community colleges) are common in downstate Illinois as a college/career readiness strategy; participation is reported in district materials and state reporting.

School safety measures and counseling resources

Illinois school safety and student support commonly include:

• Required emergency operations planning and safety drills aligned with Illinois law and ISBE guidance.
• Student services (school counselors, social work services, and mental/behavioral health supports) typically scaled to district size; staffing and supports may be listed in district report cards and school improvement plans. Because staffing levels and specific safety measures vary by building, the authoritative sources are district policies and the Illinois Report Card school environment/support indicators.

Employment and Economic Conditions

Unemployment rate (most recent year available)

The most consistently cited official local measure is the annual average unemployment rate from the U.S. Bureau of Labor Statistics (LAUS). Greene County’s most recent annual rate is published through BLS/IDES local area tables; see the BLS Local Area Unemployment Statistics (LAUS) program and Illinois releases via the Illinois Department of Employment Security.
Proxy note: Without extracting the exact annual value in this summary, Greene County’s unemployment rate generally tracks rural Illinois trends and is often near state levels but with year-to-year variability due to a smaller labor force.

Major industries and employment sectors

Industry composition is best documented through the ACS “industry by occupation” profiles on data.census.gov. Greene County’s employment base typically includes:

• Educational services and health care/social assistance (public schools, clinics, long-term care)
• Retail trade and accommodation/food services (small-town main street and service economy)
• Manufacturing (often smaller facilities relative to metro counties)
• Agriculture, forestry, fishing and hunting and related agribusiness (more prominent than in urban Illinois)
• Public administration (county and municipal services)

Common occupations and workforce breakdown

Occupational structure reported in ACS commonly shows higher shares in:

• Service occupations (food service, personal care, protective services)
• Sales and office occupations
• Production, transportation, and material moving
• Management, business, and financial (smaller share than metro areas but present)
• Construction and extraction (often tied to local building trades and regional contracting)

Commuting patterns and mean commute time

ACS commuting indicators on data.census.gov typically show rural-county patterns:

• High reliance on driving alone to work
• Limited public transit commuting
• Commute times that are often moderate (commuting to Jacksonville, Springfield-area edges, or other nearby employment centers can raise the mean/median).
  Proxy note: In rural west‑central Illinois, mean commute times commonly fall in the ~20–30 minute range; the precise Greene County mean/median is available directly in ACS commuting tables.

Local employment versus out‑of‑county work

Greene County exhibits a common rural dynamic: a portion of residents work locally in schools, health care, retail, government, and agriculture, while out‑commuting occurs to nearby counties for higher-density job markets and specialized employers. The ACS “place of work” and commuting flow information provides the most direct evidence of out‑of‑county commuting, and regional planning materials may also summarize worker flows.

Housing and Real Estate

Homeownership rate and rental share

Homeownership and tenure are reported in ACS housing profiles on data.census.gov. Greene County typically shows:

• Higher homeownership rates than Illinois overall (a common rural pattern)
• A smaller rental market, concentrated in the largest towns and near employment nodes

Median property values and recent trends

• Median owner‑occupied home value is available from ACS (and often corroborated by county assessor and real estate market summaries). Greene County’s median values generally fall well below the Illinois statewide median, reflecting rural pricing and lower land/improvement costs outside metro areas.
• Recent trends: Like many U.S. markets, downstate Illinois experienced price increases during 2020–2022, with more mixed or slower growth afterward relative to major metros.
  Proxy note: For definitive county medians and year-over-year changes, ACS 1‑year data are often unavailable for smaller counties; ACS 5‑year estimates are the standard reference for Greene County.

Typical rent prices

Gross rent medians are available through ACS. Greene County typically has:

• Lower median gross rent than the Illinois average, with rentals concentrated in small multifamily buildings, single-family rentals, and limited apartment stock.

Types of housing

Greene County housing stock is predominantly:

• Single‑family detached homes in towns and unincorporated areas
• Farmhouses and rural lots with larger parcels
• Small multifamily properties (duplexes and small apartment buildings) mainly in Carrollton, White Hall, and other incorporated areas
  Manufactured housing is also a common component of rural Midwest housing supply.

Neighborhood characteristics (proximity to schools or amenities)

• Town centers (Carrollton, White Hall) typically provide the closest access to schools, parks, basic retail, and civic services.
• Unincorporated and rural areas offer larger lots and agricultural adjacency but require longer drives for schools, health care, and shopping. Because the county is small and communities are compact, many in-town neighborhoods have relatively short driving distances to schools and municipal amenities, while rural residents depend on county and state routes.

Property tax overview (average rate and typical homeowner cost)

Illinois property taxes are primarily levied by local taxing districts (school districts are usually the largest share). Greene County effective property tax rates and bills vary widely by location, assessed value, exemptions, and overlapping districts.

• Official billing and assessed value information is maintained by the county assessment and tax offices; summary tax rate context is often available through county sources and Illinois transparency reporting.
• As a statewide context, Illinois has comparatively high effective property tax rates relative to many states, but downstate home values are lower, which can moderate total annual bills compared with high-value suburban areas.
  For county-specific effective rates and typical tax bills, the most direct reference points are the Greene County property tax bills/assessor records and comparative datasets such as the Illinois Department of Revenue publications on property taxation (statewide methodology and context), supplemented by local levy information.

Primary data sources used for the most recent available measures: U.S. Census Bureau (ACS) for education attainment, commuting, and housing; Illinois Report Card for school rosters, staffing, and graduation rates; BLS LAUS and IDES for unemployment.
