Jefferson County is located in eastern Missouri, immediately south of the St. Louis metropolitan area, with the Mississippi River forming much of its eastern boundary. Established in 1818 and named for Thomas Jefferson, the county historically linked river commerce, agriculture, and early lead-mining activity in the region, and it continues to reflect a transition between metropolitan St. Louis and the Ozark-influenced interior. Jefferson County is a large county by population, with roughly 225,000 residents, and it includes a mix of suburban communities and rural townships. The landscape features river bluffs, bottomlands along the Mississippi, and rolling wooded terrain farther west. Its economy is diversified, with many residents commuting to jobs in the St. Louis area alongside local manufacturing, retail, and service employment. The county seat is Hillsboro, while Arnold and Festus are among its largest cities.

Population Size

According to the U.S. Census Bureau QuickFacts for Jefferson County, Missouri, the county’s population was 223,702 (2020).

Age & Gender

County-level age distribution and sex composition are published by the U.S. Census Bureau in QuickFacts and the American Community Survey (ACS). For the most current county profile tables, see:

Racial & Ethnic Composition

Race and Hispanic/Latino origin for Jefferson County are reported by the U.S. Census Bureau. The county-level breakdown is available in:

Household & Housing Data

Key household and housing indicators—such as number of households, average household size, owner-occupied housing rate, median value, and housing units—are published by the U.S. Census Bureau for Jefferson County. County-level figures are available in:

Email Usage

Jefferson County, Missouri is largely suburban-to-rural with dispersed settlements outside the St. Louis metro edge, making last‑mile broadband deployment more variable than in dense urban areas and shaping reliance on internet-based communication such as email.

Direct county-level email-usage statistics are not typically published; email adoption is commonly proxied using household internet/broadband subscription and computer access from the U.S. Census Bureau data platform. These indicators capture the basic capacity to use email at home but do not measure frequency of use or workplace/mobile access.

Digital access indicators for Jefferson County can be summarized using American Community Survey tables on (1) broadband internet subscriptions and (2) presence of a computer in the household (desktop/laptop/tablet). Lower levels of either generally correspond to reduced routine email access.

Age structure influences email adoption because older adults are less likely to use some online services and may face digital-skills barriers; county age distributions are available via ACS age tables. Gender composition is less predictive than age for basic email access and is typically near parity in ACS profiles.

Connectivity limitations are reflected in reported broadband availability gaps and rural service constraints documented by the FCC National Broadband Map.

Mobile Phone Usage

Jefferson County is located in eastern Missouri, south of the St. Louis metropolitan core, along the Mississippi River. The county includes a mix of suburban/exurban development (particularly in the northern portion closest to the St. Louis region) and lower-density rural areas elsewhere. Terrain includes river valleys and rolling uplands that can contribute to localized signal variability (especially for mid- and high-band cellular frequencies), while population density and proximity to major corridors (such as I‑55 and US‑61/67) generally support stronger commercial incentives for network buildout in higher-traffic areas. County context and baseline demographics are available through Census.gov QuickFacts for Jefferson County, Missouri.

Key distinction: network availability vs. adoption

  • Network availability (supply-side): where mobile operators provide 4G/5G coverage, and where mobile broadband service is technically available.
  • Adoption (demand-side): the share of households or individuals actually subscribing to mobile service, owning smartphones, and using mobile internet.

County-level reporting often provides stronger evidence for availability (via coverage maps and broadband availability datasets) than for adoption (which is more commonly reported at state or multi-county geographies). Statements below separate these two where the underlying sources allow.

Mobile penetration and access indicators (adoption)

Household internet subscription and “cellular data only” use

The most consistently published adoption indicators for counties come from the U.S. Census Bureau’s American Community Survey (ACS), which includes measures such as:

  • households with an internet subscription,
  • type of internet subscription (including cellular data plan),
  • device access (smartphone, computer).

County estimates can be retrieved via ACS tables using data.census.gov (search within Jefferson County, MO for “internet subscription” and “cellular data plan”). The Census Bureau also publishes methodology and definitions through the American Community Survey (ACS) program pages.

Limitation: Public-facing summaries frequently emphasize overall broadband subscription; “cellular data plan only” is available in ACS tables but is not consistently summarized in narrative county profiles. For Jefferson County, definitive percentages require pulling the relevant ACS table values directly from data.census.gov for the chosen 1‑year or 5‑year ACS release.

Mobile as a substitute for home broadband

Nationally, “cellular data plan only” households are a known category in ACS. County-level estimates can vary with income, housing density, and fixed broadband availability. Jefferson County-specific substitution rates are measurable in ACS, but are not uniformly reported in secondary sources at the county level. For the authoritative county estimates, use ACS tables (commonly derived from table groups related to “Types of Computers and Internet Subscriptions”).

Mobile internet usage patterns and network generation (availability)

4G LTE availability

4G LTE is generally the baseline mobile broadband layer across the United States, including Missouri counties. The most standardized federal source for broadband/mobile availability reporting is the FCC’s Broadband Data Collection and National Broadband Map:

How it applies to Jefferson County: The FCC map supports county-level viewing for mobile broadband availability, but the most precise interpretation is location-based (point or area) rather than a single countywide percentage. Coverage quality also varies by spectrum band, terrain, and tower density.

5G availability (and variation by 5G type)

5G availability in a county can reflect a combination of:

  • low-band 5G (broader coverage, similar propagation to LTE in many deployments),
  • mid-band 5G (higher capacity, moderate propagation),
  • high-band/mmWave (very high capacity, short range; usually concentrated in dense urban pockets).

County-level, operator-specific 5G availability is best represented through:

  • the FCC National Broadband Map (availability reporting),
  • and carrier coverage disclosures (useful but not standardized across carriers and not equivalent to measured performance).

Limitation: Public datasets describe availability but generally do not provide a countywide measured share of devices actively using 5G versus 4G. Device behavior depends on handset capability, plan, and radio conditions.

Performance and real-world experience

The FCC map is availability-focused. Real-world throughput and reliability vary with congestion, backhaul capacity, and indoor signal conditions. County-specific performance benchmarking is often available only through third-party measurement reports and is not uniformly published as official county statistics. For official context on broadband and mapping standards, refer to the FCC Broadband Data Collection information.

Common device types (smartphones vs. other devices)

Smartphone access (adoption indicator)

The ACS includes measures of device access, including smartphones. County-level values for smartphone presence in households can be obtained through data.census.gov by selecting Jefferson County, Missouri and locating tables describing “computer and internet use” and device types.

Interpretation guidance:

  • ACS device indicators are typically framed at the household level (whether anyone in the household has a smartphone), not a direct count of unique devices.
  • Smartphones generally dominate consumer mobile access relative to basic phones; however, precise smartphone share in Jefferson County should be taken from ACS device tables rather than inferred.

Non-phone mobile connectivity

Mobile broadband can also be used via:

  • fixed wireless/“home internet” products delivered over cellular networks (often counted as fixed broadband where offered as a fixed service),
  • hotspots and tablets.

Limitation: Public county-level reporting rarely separates smartphone-based mobile internet use from dedicated hotspots/tablets in a comprehensive way. ACS provides some device categories but does not fully enumerate all mobile-connected device types.

Demographic and geographic factors influencing mobile usage and connectivity

Population distribution and commuting ties

Jefferson County’s northern areas have stronger functional ties to the St. Louis region, with higher housing density and more commercial development relative to the county’s rural portions. In general, higher-density areas tend to have:

  • more cell sites and small cells,
  • stronger indoor coverage due to closer site spacing,
  • faster deployment of newer technologies where traffic demand is higher.

Population and housing characteristics relevant to connectivity (density, housing units, income, educational attainment) are available through Census.gov QuickFacts and detailed ACS profiles on data.census.gov.

Terrain and land cover

River valleys, wooded areas, and rolling terrain can create:

  • shadowing and weaker indoor penetration in some locations,
  • greater sensitivity to tower placement and frequency band used.

These effects influence user experience more than formal “availability,” because coverage maps may show service while indoor or in-vehicle performance varies.

Income, age, and broadband substitution

Adoption indicators such as smartphone-only access and cellular-only internet subscription tend to correlate with:

  • income and affordability constraints,
  • age distribution (device comfort and usage intensity),
  • availability and pricing of fixed broadband options.

County-level values for income and age distributions are available via ACS at data.census.gov. County-level cellular-only household internet subscription can be measured in ACS tables but often requires direct table lookup rather than relying on summarized profiles.

Local and state broadband planning context (complementary sources)

Missouri’s broadband planning resources can provide context on infrastructure initiatives and mapping, though they are not substitutes for FCC availability data or ACS adoption data. State-level broadband information is available through Missouri’s broadband program pages (Missouri Department of Economic Development). County-level government context is available from Jefferson County, Missouri’s official website, though county sites typically do not publish standardized mobile adoption metrics.

Data limitations at the county level (explicit)

  • Mobile penetration (subscriptions per person) is not typically published as an official county metric in the same way it is for countries; county adoption is better measured using ACS household device and subscription tables.
  • 5G vs 4G usage shares (actual share of residents actively using 5G) are not reliably available as official county statistics; the most defensible county-level statements focus on availability using the FCC National Broadband Map and on adoption using ACS tables.
  • Coverage maps reflect modeled/declared service and do not guarantee consistent indoor performance; local terrain and site density contribute to variability within Jefferson County.

Social Media Trends

Jefferson County is in eastern Missouri, directly south of the St. Louis metro area, with key population centers including Arnold, Festus, and De Soto. Its proximity to a major media market (St. Louis), a commuter-oriented economy, and a mix of suburban and small-town communities shape social media use around local news, schools, public safety, community groups, and event-driven communication.

User statistics (local availability and best‑fit estimates)

  • County-specific “social media penetration” is not consistently published by major survey organizations at the county level. Most reliable measurement is available at the U.S. and state/metro levels rather than for Jefferson County alone.
  • Using national benchmarks as a reference point:
  • County context that affects likely usage levels:
    • Jefferson County includes a substantial suburban population tied to the St. Louis region, which tends to support broad adoption of mainstream platforms for community and local-information uses.

Age group trends (highest usage by age)

National patterns are the most reliable proxy for county age trends:

  • 18–29: highest overall adoption across platforms; social media is near-ubiquitous in this group in national surveys. Source: Pew Research Center (2023).
  • 30–49: high usage, especially on Facebook, YouTube, Instagram; often strongest for local/community groups and parenting/school networks.
  • 50–64: moderate-to-high usage concentrated on Facebook and YouTube; comparatively lower Instagram/Snapchat/TikTok usage.
  • 65+: lowest overall usage, with Facebook and YouTube most common among users. Source: Pew Research Center (2023).

Gender breakdown (overall and platform-typical patterns)

County-specific gender splits are not typically published by platform. National survey patterns provide the best-supported breakdown:

  • Overall social media use tends to be similar for men and women in the U.S., with differences appearing more by platform than by total usage. Source: Pew Research Center (2023).
  • Platform-leaning tendencies (U.S.) commonly observed in survey reporting:
    • Pinterest skews more female.
    • Reddit skews more male.
    • Facebook/YouTube are broadly used across genders. Source: Pew Research Center (2023).

Most-used platforms (percentages from reputable surveys)

County-level platform shares are generally unavailable from public, methodologically transparent sources; the most reliable figures are national:

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

Behavioral trends (engagement patterns and preferences)

  • Video-first consumption is central: YouTube’s reach (83% of adults) indicates broad video usage across age groups, with TikTok and Instagram reinforcing short-form video engagement. Source: Pew Research Center (2023).
  • Community and local-information use is typically Facebook-led in suburban and small-city counties: local groups, school and sports updates, municipal announcements, buy/sell/trade posts, and event promotion commonly concentrate on Facebook due to its group and sharing features (consistent with its broad adoption). Source: Pew Research Center (2023).
  • Age-linked platform preference (national pattern, generally applicable to mixed-age counties):
    • Younger adults drive higher usage of Instagram, Snapchat, and TikTok.
    • Older adults concentrate more on Facebook and YouTube. Source: Pew Research Center (2023).
  • News and civic information exposure occurs on social platforms for many adults, with local issues often circulating through community pages and shared posts. Source: Pew Research Center: Social Media and News fact sheet.

Family & Associates Records

Jefferson County, Missouri maintains family and associate-related public records primarily through state and county offices. Vital records such as birth and death certificates are filed and issued through the Missouri Department of Health and Senior Services (Bureau of Vital Records) rather than the county; certified copies are available by mail, in person at the state level, and through approved vendors. Marriage and divorce records are created at the county level: marriage licenses are recorded by the Jefferson County Clerk, and divorce case files are maintained by the 22nd Judicial Circuit Court (Jefferson County) and accessible through court records systems and the clerk’s office. Adoption records are handled under state court procedures and are generally not open to public inspection.

Public databases include statewide case and docket access through Missouri Case.net (civil, criminal, and family divisions where available) and county-recorded instruments searchable via the Jefferson County Recorder of Deeds.

Privacy restrictions commonly apply to certified vital records, juvenile matters, sealed family cases, and adoption files; access is typically limited to eligible parties and authorized requesters under Missouri law.

Marriage & Divorce Records

Types of records available

Marriage records (licenses and certificates)

  • Marriage license application and license: Created and issued by the Jefferson County Recorder of Deeds as the county’s official marriage record.
  • Marriage certificate (certified copy): A certified copy of the recorded marriage record issued by the Recorder of Deeds.
  • Marriage returns: The officiant’s completed portion confirming the marriage was solemnized and returned for recording; this is typically part of the recorded marriage file.

Divorce records (dissolution of marriage)

  • Divorce decree / Judgment of Dissolution of Marriage: The final court judgment issued by the Circuit Court (generally handled through the Family Court division of the 23rd Judicial Circuit serving Jefferson County).
  • Associated case filings: Petitions, motions, settlement agreements, parenting plans, and support orders are maintained within the court case file, subject to access rules.

Annulment records

  • Judgment/Decree of Annulment: A court order declaring a marriage invalid, maintained by the Circuit Court as part of the civil/family case file.

Where records are filed and how they can be accessed

Jefferson County marriage records

  • Filed/recorded with: Jefferson County Recorder of Deeds (marriage records are recorded at the county level).
  • Access:
    • Certified copies are obtained through the Recorder of Deeds office.
    • Non-certified copies or index lookups are commonly available through the Recorder’s public records search systems and/or in-office searches, depending on the county’s current offerings and the record date range.
  • State-level context: Missouri does not maintain a single statewide repository of all county marriage licenses equivalent to the county’s recorded original; the county Recorder is the primary custodian.

  • Orders on name change requests when granted

Annulment decree (Circuit Court)

Commonly includes:

  • Case caption and case number
  • Date of judgment and judge’s signature
  • Legal basis for annulment and declaration of invalidity
  • Related orders addressing property, support, and child issues where applicable (annulments can still involve orders concerning children and finances)

Privacy or legal restrictions

General access framework

  • Missouri’s Sunshine Law governs access to public records held by governmental bodies, while court records are governed by court rules and statutes. Court records may include public and nonpublic components, and some information is restricted even when the case is publicly indexed.

Marriage records

  • Marriage records recorded by the Recorder of Deeds are generally treated as public records. Access to certified copies is routinely available through the Recorder.
  • Identifiers and sensitive details (for example, Social Security numbers) are generally not part of modern public marriage records, and records custodians apply redaction practices where required by law.

Divorce and annulment records

  • Judgments/decrees are commonly public court records, but access to specific filings can be limited by:
    • Sealing orders entered by the court
    • Confidential case types or protected information (including certain domestic violence-related records)
    • Redaction requirements for protected identifiers (for example, Social Security numbers, full financial account numbers) and certain confidential information involving minors
  • Minor-related information may be restricted or redacted in documents available to the public, even when docket entries are visible on Case.net.

Identity verification and certified copies

  • Agencies issuing certified copies may require requester identification and fees. Courts and recorders maintain certification standards to ensure the copy is legally recognized.

Education, Employment and Housing

Jefferson County is in eastern Missouri, immediately south of St. Louis County, with a mix of suburban communities along the I‑55 corridor (such as Arnold and Imperial) and more rural areas toward the county’s western and southern portions. The county is part of the St. Louis metropolitan labor and housing market, with many residents commuting to jobs in St. Louis County and the City of St. Louis. Population and other baseline community characteristics are commonly summarized in the U.S. Census Bureau’s data.census.gov tables and profiles.

Education Indicators

Public schools (counts and names)

  • A single, definitive “number of public schools” for Jefferson County varies by source and year because schools are administered by multiple independent school districts and may open/close or reorganize.
  • Public education is primarily provided by several districts serving Jefferson County communities, including (but not limited to) Fox C‑6, Jefferson R‑7, Northwest R‑1, Windsor C‑1, Dunklin R‑V, and Desoto 73 (district naming as commonly used locally and in state directories).
  • The most authoritative way to retrieve an up-to-date school list and school-by-school names is the Missouri Department of Elementary and Secondary Education (DESE) directories and district/school report pages: Missouri DESE.
    Proxy note: Without a fixed reporting year specified for the “number of schools,” this summary uses DESE as the definitive reference point for school rosters rather than publishing a potentially stale count.

Student–teacher ratios and graduation rates

  • Graduation rates and accountability metrics are published by DESE at the high-school and district level (cohort graduation rate, dropout rate, and related outcomes): DESE district and school report cards.
    Proxy note: Jefferson County does not have a single countywide graduation rate reported as a unified system; it is reported by district/school.
  • Student–teacher ratios are also typically reported at the district/school level through state and federal reporting. For consistent, comparable ratios, DESE district staffing/enrollment reporting and NCES school-level data are standard references: National Center for Education Statistics (NCES).
    Proxy note: Countywide averages vary depending on whether they are weighted by enrollment and which districts/schools are included.

Adult education levels (attainment)

  • The most consistently used, county-level adult attainment measures come from the U.S. Census Bureau’s American Community Survey (ACS) 5‑year estimates (population age 25+):
    • High school graduate or higher (age 25+): reported in ACS “Educational Attainment” tables for Jefferson County.
    • Bachelor’s degree or higher (age 25+): also reported in the same ACS tables.
  • These indicators (including percentages and counts) are available directly in ACS educational attainment tables on data.census.gov.
    Proxy note: This summary references ACS as the most recent standardized source for county-level attainment, since district-level attainment is not the same metric and is not published as a countywide adult indicator.

Notable programs (STEM, career/technical, AP)

  • Advanced Placement (AP), dual credit, and career/technical education (CTE) offerings vary by high school and district. In Jefferson County districts, commonly available pathways include CTE coursework (e.g., industrial technology, health-related programs, business/IT) and college-credit options through regional community college and university partnerships (reported by individual districts and DESE program reporting).
  • Missouri’s statewide frameworks supporting CTE and college/career readiness are administered through DESE (including CTE program standards and reporting): DESE College & Career Readiness.
    Proxy note: “Notable programs” are not uniformly cataloged at the county level; the most accurate verification is district course catalogs and DESE program pages.

School safety measures and counseling resources

  • Safety practices are implemented at the district level and commonly include secure entrances/visitor procedures, school resource officer (SRO) partnerships, emergency operations plans, and threat-assessment protocols; specific measures vary by building and district policy.
  • Counseling resources generally include school counselors and, in many districts, additional supports such as school social workers, mental-health referral pathways, and crisis response procedures; staffing levels are reported in district staffing summaries and may be referenced through DESE data and district disclosures.
    Proxy note: Publicly available, comparable school-by-school safety and counseling details are typically found in district board policies, school handbooks, and DESE guidance rather than a single countywide dataset.

Employment and Economic Conditions

Unemployment rate (most recent available)

  • The standard local-area unemployment measure is published by the U.S. Bureau of Labor Statistics (BLS) Local Area Unemployment Statistics (LAUS). Jefferson County’s most recent annual and monthly unemployment rates are available via: BLS LAUS.
    Proxy note: This summary treats LAUS as definitive; exact “most recent year” values update regularly and should be taken from the latest LAUS release for Jefferson County, MO.

Major industries and employment sectors

  • As part of the St. Louis metro economy, Jefferson County employment commonly concentrates in broad sectors such as:
    • Health care and social assistance
    • Retail trade
    • Manufacturing
    • Construction
    • Educational services
    • Transportation and warehousing
    • Accommodation and food services
  • Industry distribution for resident workers is available from ACS “Industry by Occupation / Industry” tables on data.census.gov. Employment-by-industry for jobs located in the county may differ from resident industry mix.

Common occupations and workforce breakdown

  • Occupational composition for Jefferson County residents is commonly summarized by major SOC groupings (management/business/science/arts; service; sales/office; natural resources/construction/maintenance; production/transportation/material moving). These shares are reported in ACS occupation tables: ACS occupation profiles on data.census.gov.
  • Because Jefferson County includes both suburban and rural areas, the workforce profile often shows a meaningful presence of skilled trades, production, and transportation occupations alongside health care support and professional services roles, consistent with regional metro labor patterns.
    Proxy note: The definitive percentages are those in the most recent ACS 5‑year occupational tables.

Commuting patterns and mean commute time

  • Jefferson County functions as a commuter county within the St. Louis region:
    • Means of transportation to work (drive alone, carpool, work from home, public transit) and mean travel time to work are reported in ACS commuting tables (e.g., “Travel Time to Work,” “Means of Transportation to Work”): ACS commuting tables.
  • Typical patterns are dominated by automobile commuting, with limited public transit usage relative to core urban counties. Mean commute time is reported as a single countywide estimate in the ACS.

Local employment versus out-of-county work

  • A substantial share of residents commute to employment centers outside the county, especially toward St. Louis County and the City of St. Louis.
  • The most widely used “inflow/outflow” view of where residents work (and where local jobs’ workers live) is provided through the Census Bureau’s LEHD Origin-Destination Employment Statistics (LODES).
    Proxy note: LODES provides the most systematic county-to-county commuting flows; ACS provides complementary “place of work” characteristics.

Housing and Real Estate

Homeownership rate and rental share

  • Owner-occupied vs. renter-occupied housing shares are reported by ACS (tenure tables) at the county level: ACS housing tenure tables.
    Context: Jefferson County’s housing stock and community form (suburban and rural) generally correspond to a higher homeownership share than dense urban cores, with rentals more concentrated in larger towns and along major corridors.

Median property values and recent trends

  • Median value of owner-occupied housing units is reported in ACS (county-level median value). This is the most consistent “median property value” statistic available across U.S. counties: ACS median home value tables.
  • For market trend context (sale prices over time), commonly referenced public-series sources include the Federal Housing Finance Agency (FHFA) House Price Index for metro areas and Zillow’s research series; county-level availability varies by product. A government benchmark for regional price movement is the FHFA House Price Index.
    Proxy note: ACS provides a standardized median value but is not a direct measure of current-month market pricing.

Typical rent prices

  • Median gross rent is reported by ACS at the county level: ACS median gross rent tables.
    Proxy note: Asking rents can differ from ACS gross rent (which reflects occupied units and includes utilities in many cases).

Types of housing (single-family homes, apartments, rural lots)

  • The county’s housing mix typically includes:
    • Single-family detached homes (dominant in many subdivisions and rural areas)
    • Manufactured housing in some unincorporated and semi-rural areas
    • Small multifamily buildings and garden-style apartments in larger population centers and near commercial corridors
    • Rural residential lots/acreage outside the I‑55 corridor and incorporated areas
  • The distribution by structure type (single-unit detached, multi-unit, mobile home, etc.) is reported by ACS “Units in Structure” tables: ACS housing structure tables.

Neighborhood characteristics (proximity to schools or amenities)

  • Development patterns are split between:
    • Suburban neighborhoods with closer access to schools, parks, retail corridors, and highway interchanges (notably near I‑55 and in/near municipalities such as Arnold and Festus/Crystal City area).
    • Lower-density rural areas where access to schools and services typically requires longer driving distances.
  • Walkability and amenity access vary substantially by community; countywide generalizations are less precise than tract- or place-level measures.
    Proxy note: For measurable neighborhood context, tract-level ACS and local municipal planning documents provide more specific patterns than county averages.

Property tax overview (average rate and typical homeowner cost)

  • Missouri property taxes are primarily local (schools, counties, cities, special districts). Jefferson County effective rates vary by taxing jurisdiction, assessed value classification, and levy rates.
  • Two standardized, county-level reference points:
    • Median real estate taxes paid (ACS) for owner-occupied housing: ACS real estate taxes tables.
    • Effective property tax rate comparisons are often compiled by third-party aggregators; for official levy and assessment administration, county assessor/collector information is the authoritative source (county government).
      Proxy note: A single “average rate” is not uniformly published as an official countywide statistic because levies differ materially by school district and municipality; ACS “taxes paid” is the most comparable county summary metric.
