Barnwell County

Barnwell County is located in the southwestern portion of South Carolina, in the Lower Savannah region along the Georgia border. Established in 1798 and named for Revolutionary-era leader John Barnwell, the county developed around agriculture and river-linked trade routes associated with the Savannah River corridor. Barnwell County is small in population, with roughly 20,000 residents, and remains predominantly rural in character.

The county’s landscape features gently rolling terrain, mixed forests, and farmland typical of South Carolina’s interior Coastal Plain. Land use is dominated by agriculture, timber, and related industries, alongside government and service-sector employment centered in its towns. Settlement is dispersed, with small municipalities and unincorporated communities rather than large urban centers. Local culture reflects regional Lowcountry and inland South Carolina traditions, including long-standing community institutions and agricultural heritage. The county seat is Barnwell.

Barnwell County is located in southwestern South Carolina in the Central Savannah River Area (CSRA), bordering the Savannah River corridor and adjacent to Aiken and Allendale counties. For county government and planning resources, visit the Barnwell County official website.

Population Size

According to the U.S. Census Bureau QuickFacts for Barnwell County, South Carolina, the county’s population size is reported there using official Census Bureau releases (including decennial census counts and the Bureau’s population estimates program where available). QuickFacts is the most direct Census.gov presentation for a single-county population figure and related core demographic measures.

Age & Gender

Age distribution (standard Census Bureau age brackets) and the gender split for Barnwell County are published by the U.S. Census Bureau on the county’s QuickFacts profile. For detailed tables (including finer age groups and sex by age), the Census Bureau’s data.census.gov portal provides county-level tables from the American Community Survey (ACS) and decennial census.

Racial & Ethnic Composition

Barnwell County’s racial categories and Hispanic/Latino ethnicity (reported separately from race in Census Bureau products) are provided in the county’s Census Bureau QuickFacts profile. For more granular race/ethnicity detail (including multi-racial combinations and ancestry-related tables available through ACS), use data.census.gov and filter geography to Barnwell County, SC.

Household & Housing Data

Household and housing indicators for Barnwell County—such as number of households, average household size, owner-occupied housing rate, housing units, and related housing characteristics—are published on the U.S. Census Bureau QuickFacts profile for Barnwell County. Additional county housing tables (including housing tenure, vacancy, and household type breakdowns) are available through data.census.gov using ACS datasets.

Source Notes (County-Level Availability)

The U.S. Census Bureau provides Barnwell County demographic and housing statistics through (1) QuickFacts for a curated set of commonly used measures and (2) data.census.gov for detailed tables from the ACS and decennial census. No non-Census estimates are used here; all referenced measures are sourced from Census.gov products.

Barnwell County is a largely rural county in the southern South Carolina Lowcountry, where low population density and longer distances between homes and network hubs can constrain fixed-line broadband buildout, shaping how residents access email (often via mobile connections). Direct county-level email-usage statistics are not routinely published; broadband and device access are used here as proxies because email adoption typically depends on reliable internet access and a computing device.

Digital access indicators from the U.S. Census Bureau’s data portal (American Community Survey) provide county estimates for household broadband subscriptions and computer access, which track the practical ability to use webmail and app-based email. Age structure also influences adoption: older populations tend to show lower rates of digital account use and may rely more on assisted access; Barnwell County’s age distribution can be referenced in ACS “Age and Sex” tables via the same source. Gender distribution is generally less predictive of email adoption than age and access, but county sex breakdowns are available in ACS demographic tables.

Connectivity constraints in rural areas commonly include fewer last-mile provider options, higher per-premise deployment costs, and coverage gaps; local context can be corroborated through Barnwell County government materials and statewide broadband planning resources.

Barnwell County is in the southwestern portion of South Carolina, along the Savannah River corridor near the Georgia border. The county is predominantly rural with small population centers (including Barnwell, Blackville, and Williston) and extensive agricultural and forested land. This low-density settlement pattern and the presence of riverine and wooded areas generally increase the cost and complexity of cellular coverage and backhaul compared with South Carolina’s metropolitan counties. County population size and density context can be referenced through Census.gov QuickFacts for Barnwell County.

Key distinction: network availability vs. adoption

• Network availability describes whether mobile networks (voice/LTE/5G) are advertised as serviceable in an area based on carrier-reported coverage and engineering models.
• Adoption describes whether residents actually subscribe to mobile service, use mobile internet, and rely on smartphones or other devices for connectivity.

County-level, directly measured adoption metrics specific to “mobile phone penetration” are limited; the most consistent public sources provide (a) modeled/claimed coverage at fine geographic resolution and (b) survey-based adoption at broader geographies (state or national), with some county-level indicators available for “cellular-only” households via federal surveys.

Mobile access and penetration indicators (adoption/proxy measures)

Household “cellular-only” status (proxy for mobile reliance)

A commonly used indicator of mobile reliance is the share of households that are wireless-only (no landline telephone). The primary federal source is the National Health Interview Survey (NHIS) “wireless substitution” series, which is not designed to publish reliable estimates for every county each year. For methodological context and national/state-level outputs, see the CDC/NCHS NHIS program and the CDC wireless substitution data brief series (national estimates; county-level values are generally not provided in this series).

County-level limitation: Publicly accessible, standardized county-by-county estimates of wireless-only households are not consistently available across all counties and years from NHIS outputs. Some third-party compilations exist, but they vary in methodology and are not authoritative.

Broadband subscription vs. mobile-only internet (context for adoption)

The U.S. Census Bureau’s American Community Survey (ACS) publishes county-level estimates for computer ownership and internet subscription, including whether a household subscribes via cellular data plan. This provides a partial view of mobile internet adoption at the household level (distinct from coverage). The relevant tables can be accessed via data.census.gov (search for Barnwell County, SC and “internet subscription” / “cellular data plan”).
Interpretation note: ACS measures household subscription types rather than signal quality, speed, or whether mobile service is the primary connection.

Mobile internet usage patterns and connectivity (availability)

4G LTE availability

Barnwell County is generally within the service areas of nationwide carriers that provide LTE coverage across most of South Carolina, with weaker or variable performance more likely in sparsely populated or heavily forested/riparian sections. Public, comparable availability information is best obtained from:

• The FCC National Broadband Map, which allows filtering by mobile broadband and viewing coverage by provider and technology.
• The FCC’s Broadband Data Collection (BDC) documentation describing how coverage is reported: FCC Broadband Data Collection.

County-level limitation: Carrier-reported mobile coverage can overstate real-world service in specific locations (indoors, in vehicles, or behind terrain/vegetation). The FCC map is the standard reference for reported availability, but it remains a modeled/claimed dataset.

5G availability (sub-6 GHz and mmWave distinctions)

5G presence in rural counties is often dominated by sub-6 GHz deployments (broader coverage, modest performance gains over LTE depending on spectrum and backhaul), while mmWave is typically limited to dense urban hot spots. In Barnwell County, 5G availability—where present—tends to be uneven outside town centers and primary road corridors.

Authoritative, provider-by-location views are available through:

• the FCC National Broadband Map’s mobile layers (technology filters for 5G).
• Provider coverage viewers (useful for general orientation but not standardized for cross-provider comparisons). The FCC map remains the most comparable cross-provider dataset.

Backhaul and tower siting considerations

Mobile performance depends heavily on:

• Fiber or high-capacity microwave backhaul to cell sites
• Site spacing (more towers needed in low-density terrain to maintain consistent signal)
• Vegetation and building penetration, which affects indoor performance in wooded rural areas

County-level backhaul inventories are not typically published in a complete, site-specific manner. Statewide planning context is more accessible via South Carolina’s broadband program materials, including mapping and planning documents hosted by the South Carolina Department of Commerce (broadband initiatives are often housed or coordinated through state commerce/telecom offices and related programs; published materials vary over time).

Common device types (smartphones vs. other devices)

Smartphones

In U.S. rural counties, smartphones are generally the dominant endpoint device for mobile connectivity. County-specific device-type shares (smartphone vs. basic/feature phone) are not consistently published by federal statistical programs at the county level. Practical proxies include:

• ACS estimates of cellular data plan subscriptions and computer ownership (county-level via data.census.gov), which indicate whether households rely on mobile subscriptions and whether they also maintain traditional computers.

Fixed wireless and mobile hotspot devices

Some households use:

• Mobile hotspots (dedicated hotspot devices or smartphone tethering)
• Fixed wireless (not “mobile” in the cellular-phone sense, but often delivered over similar tower infrastructure)

These categories are better captured in broadband availability datasets (FCC) and household subscription datasets (ACS) than in phone-type surveys at county scale.

County-level limitation: No single public dataset provides a definitive, current breakdown of “smartphones vs. feature phones” specifically for Barnwell County.

Demographic and geographic factors influencing mobile usage

Rurality and population density

• Lower population density reduces the economic incentive for dense tower grids and high-capacity upgrades, which can translate into larger coverage gaps and less consistent indoor service.
• Travel corridors and town centers typically receive stronger and earlier upgrades than dispersed unincorporated areas.

Population density and rural housing patterns can be verified through Census.gov QuickFacts and related ACS profiles on data.census.gov.

Income, age, and household composition (adoption-side drivers)

Mobile adoption and reliance on mobile-only internet are associated in national research with:

• Lower household income (greater likelihood of mobile-only internet)
• Younger age distribution (higher smartphone use)
• Higher shares of renters (more mobile-only patterns in many geographies)

For Barnwell County, these variables can be retrieved from ACS subject tables and profiles via data.census.gov. Direct county-level smartphone penetration is not provided, but these factors support interpretation of subscription-type patterns measured by ACS.

Geography and land cover

• Forest cover and riverine areas can reduce signal strength and increase variability, especially indoors and at the edge of cells.
• Sparse road networks and dispersed residences can increase the distance to the nearest cell site and reduce effective throughput.

Topographic and land cover datasets exist at state and federal levels, but they are not typically integrated into a county-level mobile adoption statistic. The most standardized, public-facing view remains the FCC’s availability mapping.

Data limitations and how they affect conclusions

• Availability data: The FCC National Broadband Map is the best standardized source for county-scale mobile coverage, but it reflects carrier-reported coverage and can differ from user experience. It is appropriate for distinguishing “service claimed available” vs. “not claimed.”
• Adoption data: The ACS provides county-level household subscription categories (including cellular data plans), but it does not measure signal quality and is not a direct measure of individual mobile phone ownership.
• Device-type specificity: County-level shares for smartphone vs. feature phone are not consistently published in authoritative public datasets.

Primary authoritative sources for Barnwell County reference

• FCC National Broadband Map (mobile broadband availability by technology/provider)
• FCC Broadband Data Collection (methodology and reporting framework)
• U.S. Census Bureau (ACS internet subscription types, including cellular data plan, at county level)
• Census.gov QuickFacts (county demographics and density context)
• South Carolina Department of Commerce (state broadband planning and program context)

Barnwell County is in the southwestern part of South Carolina, anchored by the City of Barnwell and smaller communities such as Blackville and Williston. It is largely rural, with employment tied to public services, agriculture/forestry, and nearby industrial and energy-related activity in the broader Savannah River region. Rural settlement patterns and broadband availability, along with an older age profile typical of many non-metro counties, tend to correlate with heavier reliance on mobile-first platforms and local community information-sharing via social networks.

User statistics (penetration / active use)

• County-specific social media penetration is not published in standard national datasets. Publicly available, methodologically consistent measures of “% of Barnwell County residents active on social media” are generally not released at the county level by major survey programs.
• Best-supported benchmark (U.S. adult baseline): Nationally, about 7 in 10 U.S. adults use social media according to the Pew Research Center’s Social Media Use in 2023. This provides the most reliable reference point for expected usage in Barnwell County, with local variation driven mainly by age structure, education, and connectivity.
• Connectivity context: Rural areas typically report lower home broadband adoption than urban/suburban areas, which can shape platform choice and engagement style; see Pew Research Center’s Internet/Broadband fact sheet for national broadband patterns by geography.

Age group trends (highest-use cohorts)

National patterns strongly indicate that usage is highest among younger adults, with steady declines in older age groups:

• Ages 18–29: Highest overall social media use (near-universal in Pew estimates for many platforms/categories).
• Ages 30–49: High usage, often similar to 18–29 for core platforms but lower for youth-skewed apps.
• Ages 50–64: Moderate usage; more concentrated on established platforms and messaging.
• Ages 65+: Lowest overall social media use, but still a substantial minority nationwide. Source baseline: Pew Research Center (2023 social media use).

Gender breakdown

County-specific gender splits are not typically published for social media usage. Nationally, gender differences tend to be platform-specific rather than universal, with relatively small gaps in overall social media use among adults, and more notable differences on certain platforms and use cases (e.g., visual sharing, local/community groups). Reference: Pew Research Center platform-by-platform usage.

Most-used platforms (percent using each platform)

Reliable, comparable percentages are available at the national level (county-level platform shares are generally not published openly). Pew’s adult usage estimates for 2023 show the following overall U.S. patterns:

• YouTube: 83%
• Facebook: 68%
• Instagram: 47%
• Pinterest: 35%
• TikTok: 33%
• LinkedIn: 30%
• WhatsApp: 29%
• Snapchat: 27%
• X (formerly Twitter): 22% Source: Pew Research Center, Social Media Use in 2023.

Behavioral trends (engagement patterns and platform preferences)

• Video-centric consumption dominates: High YouTube reach nationally, plus growth in short-form video behaviors tied to TikTok and Instagram, supports a strong “watch-first” pattern rather than text-first posting. (Baseline: Pew 2023 platform usage.)
• Local information-sharing typically concentrates on Facebook in rural areas: Community announcements, school/sports updates, local events, and buy/sell activity often cluster in Facebook Groups and pages due to network effects and established adoption among older and middle-age adults. (Supported by Facebook’s comparatively high national penetration and older-skewing usage relative to youth apps in Pew’s cross-tabs.)
• Age-driven platform bifurcation:
  • 18–29: Higher relative concentration on Instagram, TikTok, and Snapchat alongside YouTube.
  • 50+ / 65+: Higher relative concentration on Facebook and YouTube; lower on Snapchat and TikTok. (Baseline: Pew platform demographics.)
• Mobile-first engagement is structurally favored in rural counties: Where home broadband is less prevalent, social media use leans toward smartphone access, which typically increases reliance on app-native video, messaging, and algorithmic feeds over link-heavy browsing. (Connectivity baseline: Pew broadband fact sheet.)

Barnwell County family and associate-related public records are primarily maintained through South Carolina state agencies and the county court system. Vital records (birth and death certificates) are issued by the South Carolina Department of Public Health, Vital Records; certified copies are ordered through the state’s Vital Records office and related service options listed on the agency site (SCDPH Vital Records). Adoption records are generally handled through the family court process and are not treated as open public records.

Court-related family records (marriage licenses/returns, divorce and family court filings, name changes, and related orders) are maintained by the Barnwell County Clerk of Court. In-person access and office contact information are provided on the county’s Clerk of Court page (Barnwell County Clerk of Court). Some case indexes and docket information may be accessible through the South Carolina Judicial Branch’s public index portal (South Carolina Public Index), which includes Barnwell County coverage for many record types.

Property-related associate records (deeds, mortgages, plats) are typically maintained by the county Register of Deeds and may be searchable through county or vendor systems referenced from the county website (Barnwell County, SC official site). Privacy restrictions commonly apply to juvenile matters, sealed adoption files, and certain protected personal identifiers in public filings.

Types of records available

Marriage records

• Marriage licenses: Issued by the county probate court and used to authorize a marriage.
• Marriage certificates/returns: Proof that a marriage occurred, typically completed by the officiant and returned for recording after the ceremony. South Carolina maintains an official statewide marriage record beginning in the early 20th century (commonly referenced as 1911 forward), with local issuance handled by the county.

Divorce records

• Divorce decrees (final orders): Court judgments dissolving a marriage, issued by the family court.
• Divorce case files: May include pleadings, financial declarations, settlement agreements, custody/visitation orders, and related motions and orders.

Annulment records

• Annulment decrees/orders: Court orders declaring a marriage void or voidable under South Carolina law, maintained in the family court’s case records.

Where records are filed and how they can be accessed

Marriage (Barnwell County)

• Filed/issued locally: Barnwell County marriage licenses are issued by the Barnwell County Probate Court. The completed marriage return is recorded as part of the county’s records.
• State-level record copy: South Carolina’s Department of Public Health (DPH), Vital Records maintains statewide marriage records for covered years and issues certified copies under state rules.
• Access methods:
  • Probate Court: In-person requests for local marriage license records and related documents, subject to office procedures and identification requirements.
  • DPH Vital Records: Requests for certified marriage certificates through the state vital records system.

Divorce and annulment (Barnwell County)

Identification and fees are typically required.
• Court records (divorce/annulment): Final decrees are generally public court records unless sealed, but access to full case files can be limited by court rules (for example, sealed cases, confidential family court materials, or documents protected by privacy rules). Certified copies are issued through the Clerk of Court under court procedures.

Sealing, redaction, and protected information

• Family court confidentiality: Portions of family court files may be confidential or sealed, particularly materials involving minors, sensitive personal information, or matters restricted by statute or court order.
• Personal identifiers: Social Security numbers, financial account numbers, and certain contact information may be restricted from public display or subject to redaction under court rules and privacy practices.

Barnwell County is in the southwestern part of South Carolina in the Central Savannah River Area (CSRA), bordering the Savannah River region and including the county seat of Barnwell and communities such as Blackville, Williston, and Snelling. It is a largely rural county with relatively low population density, an older housing stock outside the small town centers, and an economy influenced by public services, retail, manufacturing, and nearby regional employment hubs. (For baseline demographics and regularly updated county profiles, see the U.S. Census Bureau QuickFacts for Barnwell County.)

Education Indicators

Public schools (count and names)

Barnwell County is served primarily by Barnwell County School District (BCSD 45). Public school counts and specific school names vary over time due to consolidations and grade reconfigurations; the authoritative current roster is maintained by the district and state report cards:

• BCSD 45 district and school directory information is available via the Barnwell County School District 45 website.
• Official school listings and performance metrics are published in the South Carolina School Report Cards system.

Because school openings/closures and naming can change, school names are best taken from the two sources above rather than secondary datasets.

Student–teacher ratios and graduation rates

• Student–teacher ratio: The most consistently comparable student–teacher ratio figures are typically reported at the district/school level in state report cards rather than county aggregates. Barnwell County’s ratios are available for each school on South Carolina School Report Cards (look up each BCSD 45 school).
• Graduation rate: South Carolina reports 4-year adjusted cohort graduation rates by high school. Barnwell County high schools’ graduation rates are published on South Carolina School Report Cards. A single countywide graduation rate is not always presented as a consolidated metric when multiple high schools exist or when grade spans are organized differently.

Proxy note: When countywide single-number indicators are not published, school-level report cards serve as the most reliable proxy for current student–teacher ratios and graduation outcomes in Barnwell County.

Adult educational attainment (countywide)

Adult attainment is tracked through the American Community Survey (ACS) and summarized by the Census:

• High school diploma or higher (age 25+): Reported in QuickFacts (ACS 5-year).
• Bachelor’s degree or higher (age 25+): Also reported in QuickFacts (ACS 5-year).

These ACS-derived percentages are the standard county-level indicators used for benchmarking educational attainment.

Notable programs (STEM, vocational, AP)

Barnwell County public secondary programming is typically documented through district course catalogs and school report cards:

• Career and Technical Education (CTE)/vocational pathways: South Carolina supports CTE through statewide frameworks; Barnwell County offerings are reflected in BCSD 45 materials and SC report cards. Reference: South Carolina Department of Education (SCDE) Career and Technical Education.
• Advanced Placement (AP) and college-credit opportunities: AP participation/performance indicators (where offered) appear on each high school’s SC School Report Card.
• STEM-related coursework and initiatives: STEM is generally embedded through math/science sequences and CTE clusters; specific school STEM initiatives are most reliably identified in district/school publications (BCSD 45) and SCDE program pages.

School safety measures and counseling resources

South Carolina schools operate within statewide safety expectations (e.g., emergency preparedness, threat assessment processes, visitor controls) and student support frameworks:

• District-level safety policies, school resource officer (SRO) arrangements (where applicable), and emergency procedures are typically posted by the district: BCSD 45.
• School counseling services are generally part of standard staffing (school counselors, referrals to community services), with student support indicators and narrative elements sometimes included on SC School Report Cards.
• Statewide student support guidance is maintained by SCDE (including counseling frameworks): South Carolina Department of Education.

Availability note: Public, countywide counts of counselors/SROs are not consistently published in a single table for Barnwell County; district postings and school report cards are the primary public references.

Employment and Economic Conditions

Unemployment rate (most recent available)

The most current official unemployment rates are published monthly through the U.S. Bureau of Labor Statistics (BLS) Local Area Unemployment Statistics (LAUS):

• Barnwell County unemployment rate (latest month and annual averages): BLS LAUS (county series can be accessed via LAUS data tools and releases).

Proxy note: When a single “most recent year” figure is needed, the most recent annual average unemployment rate from LAUS is the standard comparable metric.

Major industries and employment sectors

County sector composition is typically derived from ACS “industry by occupation” and labor market summaries:

• Barnwell County’s workforce is commonly concentrated in educational services/health care, retail trade, manufacturing, public administration, and construction/transportation (sector shares and counts appear in ACS tables summarized through Census profiles).
• County economic profile sources include:
  • QuickFacts (employment and economy indicators)
  • data.census.gov (ACS industry and occupation tables)

Common occupations and workforce breakdown

Typical occupation groups in rural South Carolina counties, including Barnwell, often show higher shares in:

• Service occupations (healthcare support, protective service, food service)
• Sales and office
• Production, transportation, and material moving
• Construction and extraction
• Management/professional at a smaller share than metropolitan counties

Authoritative county-specific distributions are available through ACS occupation tables on data.census.gov (e.g., occupation by sex/age; employed civilian population by occupation).

Commuting patterns and mean commute time

Commuting metrics (drive-alone, carpool, remote work, mean travel time to work) are measured by ACS:

• Barnwell County’s mean travel time to work and commute mode shares are published via data.census.gov and summarized in QuickFacts (where shown).

Rural counties in the CSRA commonly have car-dominant commuting with limited transit availability; Barnwell County’s exact commute-time average and mode split should be taken from the most recent ACS 5-year tables.

Local employment vs. out-of-county work

The ACS provides “place of work” patterns (work in county vs. outside county) in commuting flow tables:

• Barnwell County residents commuting to jobs outside the county is a documented pattern in rural areas near larger employment centers; the county-specific in-county vs. out-of-county shares can be drawn from ACS commuting tables on data.census.gov.

Availability note: A single standardized “local employment retention rate” is not always presented in an easy county profile; ACS commuting tables are the best public proxy for resident work location.

Housing and Real Estate

Homeownership rate and rental share

Homeownership and tenure are reported through ACS:

• Owner-occupied vs. renter-occupied housing unit shares are available in QuickFacts and in detailed ACS housing tables on data.census.gov.

Median property values and recent trends

• Median value of owner-occupied housing units: Reported in QuickFacts (ACS 5-year), representing a multi-year estimate rather than a real-time market price.
• Recent trends (proxy): In rural South Carolina counties, ACS median value often lags faster-moving listing markets. For market-trend context (sales price trends, inventory), county-level real estate portals may provide estimates, but ACS remains the standard official statistical source.

Typical rent prices

• Median gross rent: Reported via QuickFacts and detailed ACS tables on data.census.gov.
• Barnwell County rents typically reflect a small-town/rural market with fewer large multifamily developments than metro areas; median gross rent from ACS is the most consistent benchmark.

Types of housing

Barnwell County’s housing stock is generally characterized by:

• Single-family detached homes as the dominant structure type (common in rural counties)
• A smaller share of manufactured homes/mobile homes relative to urban counties
• Limited apartment/multifamily concentration, typically clustered near town centers (Barnwell, Blackville, Williston)

Structure-type distributions are available through ACS “units in structure” tables on data.census.gov.

Neighborhood characteristics (proximity to schools/amenities)

• Housing near town centers (Barnwell, Blackville, Williston) tends to have closer proximity to schools, civic facilities, and small retail corridors, while housing outside these areas is more likely to be on larger rural lots with longer drive times to services.
• Public school locations and attendance areas are best identified using BCSD 45 resources and mapping tools:
  • BCSD 45 district information
  • South Carolina Department of Education (district references and statewide context)

Property tax overview (rate and typical homeowner cost)

South Carolina property taxes vary substantially by assessment ratio (primary residence vs. other property) and local millage rates:

• Owner-occupied primary residences are generally assessed at a lower ratio than non-primary residences, which reduces typical tax burdens for qualifying homeowners.
• The most reliable public explanation of South Carolina property tax mechanics (assessment ratios, millage, exemptions such as the legal residence provisions) is provided by the state:
  • South Carolina Department of Revenue (property tax overview)

Availability note: A single “average effective property tax rate” for Barnwell County is not consistently published as an official county statistic in the same way ACS publishes value/rent. County auditor/treasurer postings and state tax guidance provide the most direct documentation of millage and billing rules.
