Union County

Union County is a county in central Ohio, located northwest of Columbus and bordered by the Scioto River along part of its eastern edge. Established in 1820 and named for the federal Union, it developed as an agricultural area connected to nearby regional markets and later to the expanding Columbus metropolitan economy. The county is mid-sized in population, with a mix of long-established small towns and newer suburban growth, particularly in the southeast. Its landscape is largely flat to gently rolling, shaped by glacial plains, with extensive farmland and scattered woodlands. Agriculture remains important, while employment and development are also influenced by proximity to Columbus, including logistics, manufacturing, and service-sector commuting. Cultural life reflects a blend of rural traditions and exurban community patterns. The county seat is Marysville, the largest city in the county and a primary center for government, industry, and local services.

Union County is a county in central Ohio, northwest of the Columbus metropolitan core, and includes the City of Marysville as the county seat. The county is part of the broader Central Ohio region tied to the Columbus-area economy and growth corridor.

Population Size

According to the U.S. Census Bureau QuickFacts for Union County, Ohio, Union County had an estimated population of 70,818 (July 1, 2023).

The most current figures for Union County are provided under “Housing” and “Families & Living Arrangements” in the Union County, Ohio QuickFacts table.

Local Government & Planning Reference

For local government information and county planning resources, visit the Union County, Ohio official website.

Union County, Ohio combines fast-growing suburban areas (Marysville, Jerome Township) with lower-density rural townships, creating uneven infrastructure buildout that shapes digital communication access.

Direct county-level email usage statistics are not published; email adoption is therefore proxied using household internet/broadband subscription, computer availability, and demographic structure from the U.S. Census Bureau (data.census.gov). These indicators track the practical ability to create and regularly use email accounts.

Digital access indicators show that most households report internet service and computing devices, but gaps persist for lower-income and rural households, where last‑mile costs and provider coverage can constrain service quality. Age distribution also influences email reliance: Union County’s sizable working‑age population supports routine email use for employment, school, and services, while older adults are more likely to face adoption and accessibility barriers. Gender distribution is broadly balanced and is generally a weaker predictor of email use than age, income, and education.

Connectivity limitations are shaped by rural distance from fiber routes and reliance on cable/DSL, fixed wireless, or cellular options. County planning context is summarized on the Union County government website.

Overview and local context

Union County is in central Ohio, northwest of Columbus, and includes the City of Marysville along with smaller villages and extensive agricultural land. The county’s mix of a growing suburban/commuter area near the Columbus metro and lower-density rural townships affects mobile connectivity outcomes: rural road networks and wider spacing between homes generally require more tower density to deliver consistent coverage and high-capacity mobile broadband, while the Marysville/US-33 corridor concentrates demand and tends to receive earlier network upgrades. County geography is predominantly flat to gently rolling, which is generally favorable for radio propagation compared with mountainous terrain, but population distribution and site availability remain primary determinants of coverage quality and network capacity.

Data limitations and how indicators are interpreted

County-level statistics on “mobile penetration” (such as the share of residents with a mobile subscription) are not consistently published in a single authoritative county dataset. Publicly available sources more commonly provide:

• Household device adoption indicators (e.g., smartphone ownership or cellular data-only plans as a form of internet subscription) from the U.S. Census Bureau’s American Community Survey (ACS).
• Network availability indicators (e.g., where 4G/5G service is reported available) from the Federal Communications Commission (FCC) and related mapping programs.

These measures describe different things. Network availability indicates where providers report service as available. Household adoption indicates whether residents actually subscribe to mobile service or use cellular connections for internet access.

Network availability (coverage) in Union County

FCC-reported mobile broadband availability (4G/5G)

The primary public reference for provider-reported mobile broadband coverage in the United States is the FCC’s Broadband Data Collection and National Broadband Map. These data show where carriers report coverage by technology and are best used as an availability indicator rather than a performance guarantee.

• FCC mobile availability layers can be explored through the FCC National Broadband Map.
• The FCC’s broader program documentation and methodology for availability reporting is published by the FCC Broadband Data Collection.

Union County availability pattern (high-level):

• 4G LTE service is generally reported as widely available across central Ohio counties, including Union County, though coverage quality and indoor signal can vary by carrier and by rural township versus the Marysville area.
• 5G availability in Union County is typically strongest in and near population centers and major roadways (notably around Marysville and regional transport corridors). As in most U.S. counties, 5G coverage tends to be less uniform than LTE in rural areas, and high-capacity 5G deployments (often associated with denser cell sites) are more common in more built-up areas.

Important distinction: FCC map layers are based on provider submissions that can overstate real-world experience at the parcel level, especially in rural areas. Availability should be interpreted as “service is reported available somewhere in this area,” not as a guarantee of consistent signal at every address.

Public safety and coverage feedback sources

• The FCC maintains processes for consumers and local entities to challenge or provide feedback on broadband availability through map tooling and challenge frameworks referenced on the FCC National Broadband Map site.

Household adoption and usage indicators (actual use)

Mobile device adoption and mobile-only internet (ACS)

The most widely used, regularly updated public measure of technology adoption at the local level is the ACS. Relevant ACS tables include:

• Computer and internet access measures, including whether households have a smartphone and whether they subscribe to internet service using a cellular data plan.
• These estimates can be accessed via Census.gov data tools and described in the Census Bureau’s technical documentation.

What the ACS can indicate for Union County:

• Smartphone presence in households (share of households reporting a smartphone).
• Cellular data plan as an internet subscription (households using a cellular plan for internet access; often interpreted as “mobile internet adoption” or “mobile-only/home-as-mobile” usage when not paired with another home internet subscription).

Limitations:
ACS data describe household-reported adoption, not network quality. The ACS also does not directly report “4G vs 5G usage,” and it does not publish carrier-specific adoption at the county level.

Interpreting “mobile penetration” locally

At the county scale, “mobile penetration” is typically approximated using:

• Household smartphone availability (ACS).
• Household cellular data plan subscriptions for internet (ACS).
• Broader subscription counts are usually carrier-held and not released at county granularity in a standardized public dataset.

Mobile internet usage patterns (how mobile is used)

Typical county-level observable patterns (from public indicators)

Public datasets support several measurable patterns without inferring undocumented behaviors:

• Areas with more limited fixed broadband options often show higher reliance on cellular data plans for home internet access in ACS estimates.
• Commuter proximity to Columbus and employment centers can correlate with higher smartphone adoption and greater data consumption, though county-specific usage volumes (GB/month) are not available in a standardized public dataset.

For Union County, the combination of a growing population base near Marysville and rural townships suggests that:

• Network load and capacity demand are more concentrated near the city and along commuting corridors.
• Cellular-only internet subscriptions may be more prevalent in portions of the county where fixed broadband options are less available or less affordable, as reflected (when present) in ACS cellular plan subscription estimates rather than inferred from coverage maps.

Common device types (smartphones vs. other devices)

Household device categories available in ACS

The ACS distinguishes between device types present in the household, including:

• Smartphone
• Desktop/laptop
• Tablet
• Other/none (depending on table structure and year)

County-level estimates for these device categories can be retrieved through Census.gov (ACS computer and internet access tables) for Union County.

Interpretation:

• Smartphones are the principal mobile access device captured directly by ACS.
• Tablets can contribute to mobile-like usage but are not necessarily connected via cellular plans.
• The ACS does not directly enumerate IoT devices or hotspot devices at a county level in a consistent way.

Demographic and geographic factors influencing mobile usage and connectivity

Population density and settlement pattern

• Union County’s split between Marysville’s denser development and lower-density rural townships influences both availability and experience. Lower-density areas generally require more infrastructure per user to provide equivalent coverage and capacity, which can affect both signal consistency and the economics of rapid upgrades.

Income, affordability, and substitution between fixed and mobile broadband

• ACS internet subscription types (including cellular data plans) can be used to evaluate whether households are substituting mobile service for fixed broadband. Affordability pressures often appear as higher cellular-only subscription shares, but the ACS provides the measurement while reasons for substitution are not directly attributable in county tables.

Commuting and corridor effects

• Central Ohio commuting patterns concentrate usage along highways and in employment centers. Network operators commonly prioritize upgrades where traffic volume and demand are highest, which tends to improve availability and capacity in these corridors compared with sparsely traveled rural areas.

Local and state references for connectivity planning context (non-carrier specific)

• The Ohio Broadband Office provides statewide broadband planning materials and context that can be used alongside FCC map layers for understanding availability initiatives (primarily fixed broadband, but relevant to overall connectivity conditions).
• Local government context and planning references are available through the Union County government website, which can help situate development patterns that affect network demand (land use, growth areas, and infrastructure planning).

Clear separation: availability vs. adoption (summary)

• Network availability (4G/5G): Best measured using the FCC National Broadband Map, which reflects provider-reported service areas and technology layers.
• Household adoption (devices and subscriptions): Best measured using the U.S. Census Bureau ACS on Census.gov, which captures household smartphone presence and cellular data plan internet subscriptions.
• County-level “mobile penetration” in the sense of subscription rates per person: Not consistently available as an official public county metric; ACS household indicators are the closest standardized proxy available without relying on proprietary carrier data.

Union County is in central Ohio on the northwest edge of the Columbus metro area, with Marysville as the county seat. Its rapid population growth, commuting ties to Columbus, and major advanced‑manufacturing presence (including Honda’s Ohio operations) contribute to a mix of suburban, exurban, and small‑town communication patterns that generally align with broader U.S. and Ohio social media usage trends.

User statistics (penetration and active use)

• County-specific platform penetration figures are not published consistently at the county level by major public survey programs. The most defensible local baseline uses national benchmarks and local demographics (Union County’s relatively high share of working-age adults and families compared with many rural counties tends to track with high social media adoption).
• U.S. adult adoption: About 69% of U.S. adults report using at least one social media site (Pew Research Center, 2023). Source: Pew Research Center: Social Media Use in 2023.
• Teen adoption (relevant for school-age residents): Social media and video-first platforms are near‑universal among teens; YouTube is used by the large majority of U.S. teens, and TikTok/Snapchat/Instagram are widely used. Source: Pew Research Center: Teens, Social Media and Technology 2023.
• Interpretation for Union County: Given its Columbus-adjacent suburban growth and workforce participation, overall social media participation is commonly expected to be at least in line with the ~7-in-10 U.S. adult benchmark, with especially high usage among teens and adults under 50.

Age group trends (who uses social media most)

National patterns that typically map onto counties with similar demographics:

• Highest use: Ages 18–29 and 30–49 show the highest overall social media participation and the broadest multi‑platform use (Pew, 2023).
• Moderate use: Ages 50–64 remain majority users but with narrower platform mixes and lower posting frequency than younger cohorts (Pew, 2023).
• Lowest use: 65+ use is substantial but lowest among age groups and is more concentrated on a smaller set of platforms (notably Facebook) (Pew, 2023).

Gender breakdown

• Overall social media use by gender is broadly similar in U.S. adult survey results, with platform‑level differences:
  • Women tend to over‑index on visually oriented and community interaction platforms such as Pinterest and often show slightly higher use on Facebook/Instagram in some survey cuts.
  • Men tend to over‑index on discussion/news and certain video/gaming-adjacent communities and often show relatively higher presence on Reddit and some creator/streaming niches.
• Source for platform-by-demographic patterns: Pew Research Center demographic tables (Social Media Use in 2023).

Most-used platforms (percentages where available)

National adult usage shares (often used as the best public proxy where county-level data are unavailable), from Pew Research Center (2023):

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

Union County’s platform mix generally aligns with these rankings, with Facebook and YouTube typically serving as the broadest-reach channels across ages, while Instagram/TikTok/Snapchat are disproportionately concentrated among younger residents.

Behavioral trends (engagement patterns and preferences)

• Multi-platform “stacking” is common among younger users: Teens and adults under 30 tend to maintain accounts across multiple services, using different platforms for distinct purposes (short-form video, messaging, local community updates, and entertainment). Source: Pew teen social media findings (2023).
• Short-form video drives time spent and discovery: TikTok, Instagram Reels, and YouTube Shorts influence what content is consumed and shared; YouTube remains a cross‑age “default” video platform with very high reach (Pew, 2023).
• Local information and community groups remain Facebook‑centric: Suburban and small‑city areas commonly rely on Facebook Groups/Pages for event promotion, school/community updates, and local marketplace activity; this pattern is consistent with Facebook’s broad adult reach (Pew, 2023).
• Professional networking is concentrated in working-age adults: LinkedIn usage is highest among employed adults, college‑educated residents, and commuters in metro-adjacent counties, reflecting job mobility and business networking behavior (Pew, 2023).
• Engagement skews passive for many adults: A sizable share of adults report using platforms primarily to read/watch rather than post frequently, while younger cohorts more often create/share content, especially via video and direct messaging overlays (Pew teen and adult reporting, 2023).

Union County family-related public records include vital records and court files. Birth and death records are recorded by the Union County Health Department (Vital Statistics) (and statewide through the Ohio Department of Health). Certified copies are typically obtained through the local registrar in-person or by mail; some statewide ordering options are available through Ohio’s vital records ordering services referenced by the health department. Marriage licenses are issued and recorded by the Union County Probate/Juvenile Court. Divorce and dissolution filings are maintained by the Union County Court of Common Pleas and indexed through the Clerk of Courts.

Adoption, guardianship, and juvenile matters are generally handled by Probate/Juvenile Court and are commonly restricted from public inspection under Ohio law and court rules; access is typically limited to eligible parties or by court order. Birth records are not generally open for full public viewing; certified copies are issued under state eligibility and identification requirements. Death certificates are more broadly obtainable, though certified copies are still issued through official custodians.

Public databases vary by office. Court dockets and case information may be available via online portals linked from the Union County official website, while certified vital records are accessed through the Health Department’s vital statistics office or the court clerk/probate court in-person during business hours.

Types of records available

• Marriage license records
  • Union County maintains records documenting marriage license applications and licenses issued in the county. After the ceremony, the completed marriage return is recorded with the county.
• Divorce records
  • Divorce case files and final judgments (often called divorce decrees or judgments entries/decrees of divorce) are maintained as court records for cases filed in Union County.
• Annulment records
  • Annulments are handled as domestic relations cases in the court system. Records typically include the complaint/petition, orders, and the final entry granting or denying annulment.

Where records are filed and how they can be accessed

• Marriage records (licenses and recorded returns)

  • Filed/recorded with: Union County Probate Court (marriage licenses in Ohio are issued by the probate court of the county where the license is obtained).
  • Access: Certified copies are generally obtained through the Union County Probate Court. Requests commonly require identifying information such as names and approximate marriage date; fees and identification requirements are set by the court.
  • State-level indexes: Ohio maintains statewide vital statistics services and indexes for certain years; county probate courts remain the primary custodians of marriage license records.

• Divorce and annulment records (court case files and final entries)

  • Filed with: The Union County court with domestic relations jurisdiction. In Ohio, divorce and annulment actions are commonly filed in the Court of Common Pleas (often through a Domestic Relations division or the clerk serving that function).
  • Access: Copies of final decrees and case documents are generally obtained from the Clerk of Courts office that maintains the case docket and filings. Many Ohio courts provide online docket access for basic case information; document images and certified copies are typically provided through the clerk.
  • State-level vital records (“Divorce Certificate” concept): Ohio issues divorce records in a Certificate of Divorce format through the Ohio Department of Health for certain periods; the underlying court decree remains the authoritative record for the terms and findings.

Typical information included in these records

• Marriage license/record

  • Full names of the parties
  • Date and place of marriage (county/city or venue)
  • Date the license was issued and recorded
  • Officiant name and title, and certification/return information

  • Determination that the marriage is void/voidable under Ohio law (as stated by the court)
  • Any associated orders (property, support, parentage/children-related orders where applicable)
  • Judge/magistrate and journalization date

Privacy or legal restrictions

• Public-record status

  • Ohio court records (including divorce and annulment filings) are generally public records, subject to statutory exemptions and court rules.
  • Marriage license records held by the probate court are generally available for public inspection and for issuance of certified copies, subject to identity verification and administrative requirements for certified copies.

• Sealed and restricted information

  • Courts may seal portions of a case or specific documents by order, limiting public access.
  • Certain sensitive identifiers and protected information are restricted from public disclosure or are redacted, including Social Security numbers and other personal identifiers, consistent with Ohio public-records law and court privacy rules.
  • Records involving juveniles, adoption-related matters, or specific protected proceedings can carry additional confidentiality rules; in divorce/annulment cases, filings related to minors (including some reports and evaluations) may be restricted or sealed by rule or order.

• Certified copies and legal use

  • Certified copies of marriage records and court decrees are issued by the custodial office (Probate Court for marriage records; Clerk of Courts for divorce/annulment decrees). Agencies and courts commonly require certified copies for legal purposes.

Union County is in central Ohio, directly northwest of Columbus, and is part of the Columbus metropolitan area. It is one of Ohio’s faster-growing counties, with population growth driven by suburban expansion (notably around Dublin, Marysville, and Jerome Township), a large manufacturing presence anchored by automotive production, and extensive commuting ties to Franklin County.

Education Indicators

Public school districts and schools

Union County’s public education is primarily delivered through several districts serving county residents. District boundaries overlap with adjacent counties (notably Dublin City Schools, which spans multiple counties). School lists change periodically with openings/grade reconfigurations; official district directories are the most current sources.

• Marysville Exempted Village School District (largest in-county system; Marysville and surrounding townships) — district and school directory via Marysville Exempted Village Schools.
• Union Local School District (often referred to as “Union County” schools; serves northern/western areas around Richwood and Magnetic Springs) — information via Union Local Schools.
• Fairbanks Local School District (serves areas near Milford Center and portions of northeastern Union County) — information via Fairbanks Local Schools.
• Jonathan Alder Local School District (serves Plain City and surrounding areas; portions extend into Madison/Franklin) — information via Jonathan Alder Local Schools.
• Dublin City School District (serves parts of southeast Union County; primarily based in Franklin/Delaware) — information via Dublin City Schools.

Countywide count of public schools and a comprehensive name-by-name list is not consistently published as a single, stable “Union County schools” roster because multiple districts overlap county lines and school portfolios change; district directories above function as the most reliable current source.

Student–teacher ratios and graduation rates

• Student–teacher ratio (proxy): County-specific student–teacher ratios vary by district and year and are not consistently reported in one countywide measure. A commonly used proxy is the district- or school-level ratio reported by the Ohio Department of Education and Workforce and federal school datasets; these typically fall in the mid-to-high teens in comparable central Ohio districts, with variation by grade band and enrollment growth.
• Graduation rates: Ohio reports 4-year and 5-year graduation rates by district and high school through the state report card system rather than as a single countywide statistic. The most current district/school graduation-rate results are available through the Ohio School Report Cards portal.

Adult educational attainment

Union County’s adult educational attainment is high relative to many Ohio counties, reflecting proximity to Columbus, a large professional commuting workforce, and rapid suburban development.

• For the most recent American Community Survey (ACS) county estimates, use the U.S. Census Bureau’s Union County profile in data.census.gov. Indicators typically cited include:
  • High school graduate or higher (age 25+): commonly in the 90%+ range in recent ACS releases for Union County.
  • Bachelor’s degree or higher (age 25+): commonly in the mid-30% to 40%+ range in recent ACS releases for Union County, with higher concentrations in communities tied to the Dublin/Columbus professional labor market.

(Exact current-year percentages should be taken from the most recent 5-year ACS table for “Educational Attainment” on data.census.gov; county values move year-to-year with in-migration.)

Notable academic and career programs

Across Union County districts, notable offerings typically include:

• Advanced Placement (AP) and College Credit Plus (CCP): Ohio’s statewide dual-enrollment option (CCP) is widely used in central Ohio high schools; program details and participation vary by district and are summarized in district course guides and state reporting.
• Career-technical and vocational pathways: Many students access career-tech programming through regional career centers or district partnerships; the most visible regional provider serving parts of the area is Tolles Career & Technical Center (serves multiple districts in the region; attendance depends on home district agreements).
• STEM and workforce-aligned coursework: Growth in advanced manufacturing locally supports emphasis on engineering, robotics, computer science, and pre-apprenticeship style coursework in some districts (district course catalogs and career pathways documentation are the authoritative references).

Safety measures and counseling resources

Union County districts generally follow Ohio K–12 safety requirements and standard practices common to central Ohio public schools:

• Safety planning: building-level safety plans, visitor management procedures, drills, and coordination with local law enforcement and emergency management; the operational details are typically published in district safety pages and board policies rather than in countywide statistics.
• Student support services: school counseling, mental-health supports, and referral processes are commonly provided through district student services departments; staffing levels and specific programs vary by district and are documented in district student-services webpages and annual reports.

Employment and Economic Conditions

Unemployment rate

• The most recent official county unemployment rate is published monthly by the Ohio Department of Job and Family Services and the U.S. Bureau of Labor Statistics (LAUS program). The current Union County series is accessible via FRED’s county unemployment rate pages (search “Union County, OH unemployment rate”) and through OhioLMI.
• Union County’s unemployment rate generally tracks near or below the Ohio average due to strong manufacturing employment (notably automotive) and metro-area labor demand; the exact most recent annual average should be taken from the latest published year.

Major industries and employment base

Key employment drivers include:

• Manufacturing: anchored by large-scale automotive production and suppliers (Marysville area is widely associated with Honda-related manufacturing).
• Health care and social assistance: a major sector for resident employment across central Ohio.
• Retail trade, accommodation/food services, and local services: concentrated in growing suburban nodes and along major corridors.
• Construction and real estate-related activity: supported by sustained residential and commercial development.
• Professional, scientific, and technical services (resident workforce): a significant share of residents work in professional/technical roles, frequently outside the county in the Columbus job market.

Sector detail and workforce composition by industry are available in ACS “Industry by Occupation” tables on data.census.gov and in regional labor market profiles via OhioLMI.

Common occupations and workforce breakdown

Union County’s occupational profile reflects a blend of:

• Management, business, science, and arts occupations (higher in suburban commuter areas tied to Columbus employment),
• Production, transportation, and material moving occupations (elevated relative to many suburban counties due to manufacturing/logistics),
• Sales, office, and service occupations supporting local commerce and institutions.

The most current occupation shares (percent of employed residents by major occupation group) are reported in ACS tables on data.census.gov.

Commuting patterns and mean travel time

• Commuting flows: Union County functions as both an employment center (manufacturing/industrial employment in and around Marysville) and a residential “commuter county” linked to Franklin County/Columbus. A substantial portion of residents commute out of county for work, particularly to Franklin County.
• Mean commute time: The most recent ACS “Travel Time to Work” estimate for Union County is available on data.census.gov and is typically around the mid‑20s minutes in recent years for similar Columbus-metro counties, with variation by township and proximity to I‑270/U.S. 33.

Local employment versus out-of-county work

• Out-of-county work: A significant share of employed residents work outside Union County, reflecting proximity to major employment nodes in Columbus and surrounding suburbs.
• In-county work: Manufacturing and associated supply-chain employment supports a sizable in-county job base (notably in the Marysville area).
  The most precise measure comes from the Census Bureau’s LEHD/OnTheMap commuting flow data, which reports where Union County residents work and where workers employed in Union County live.

Housing and Real Estate

Homeownership and rental share

• Union County’s housing tenure skews toward owner-occupied due to suburban single-family development and higher household incomes relative to many Ohio counties.
• The current homeownership rate and renter share are reported in ACS “Tenure” tables on data.census.gov. Recent ACS profiles for Union County typically show homeownership around ~75–80%, with the remainder renter-occupied (exact latest estimate should be taken from the most recent 5-year ACS release).

Median home values and recent trends

• Median owner-occupied home value: available via ACS (median value) on data.census.gov and via market-tracking sources (which may differ methodologically from ACS).
• Trend: Values increased substantially from 2020–2024 across central Ohio due to population growth, limited inventory, and metro-area demand spillover; Union County generally followed this pattern. The most comparable “official” long-run measure is the ACS median value series, while real-time pricing is reflected in MLS-based market reports.

Typical rent levels

• Median gross rent: reported in ACS “Gross Rent” tables on data.census.gov.
• Union County rents generally align with outer Columbus-metro pricing, with higher rents nearer Dublin and other high-demand growth areas, and lower rents in more rural parts of the county. (Exact current median should be taken from the latest ACS.)

Housing types and development pattern

• Single-family detached homes: the dominant housing type, especially in newer subdivisions around growth corridors and school-centered neighborhoods.
• Apartments and townhomes: concentrated near Dublin-influenced areas, Marysville, and newer mixed-use or higher-density projects.
• Rural lots and farm-adjacent housing: common in outlying townships, reflecting the county’s mix of suburban and rural land uses.

Housing-type shares (single-family vs multi-unit vs mobile home) are available in ACS “Units in Structure” tables on data.census.gov.

Neighborhood characteristics and proximity to amenities

• Marysville-area neighborhoods: closer to major employers and district schools, with a mix of established subdivisions and newer development.
• Dublin/Bridge Street and northwest Franklin-border areas extending into Union County: generally feature higher-cost housing, proximity to retail, offices, and metro amenities, and strong highway access.
• Plain City/Jerome Township growth areas: rapid residential construction, newer schools/campuses, and commuter-oriented neighborhood design.
• Northern/western rural communities (e.g., Richwood area): lower-density housing, larger lots, and longer travel to major retail/medical centers.

Property tax overview

• Ohio property taxes vary significantly by school district, municipality/township, and voter-approved levies; Union County bills are often driven by school funding levies and newer infrastructure needs in fast-growth areas.
• The most comparable countywide reference points are:
  • Effective property tax rate (proxy): can be approximated using ACS “Selected Housing Characteristics” (taxes paid) and assessed values, but this is an indirect method and not a formal tax-rate publication.
  • Typical homeowner cost: annual property tax paid is reported in ACS as “Real estate taxes paid” (distribution and median/mean) on data.census.gov; this provides a countywide snapshot but can lag market changes.
• Official levy rates and billed tax calculations are maintained by the Union County government offices (Auditor/Treasurer) and the Ohio Department of Taxation’s property tax publications. For statewide context, see the Ohio Department of Taxation property tax resources.

Data availability note: Several requested indicators (countywide public-school counts, countywide student–teacher ratio, and a single county graduation rate) are not standard county-level publications because reporting is district/school-based and district boundaries cross county lines. The authoritative sources are district directories and the Ohio School Report Cards portal for current school lists, ratios, and graduation-rate metrics by school/district.
