Perkins County is located in northwestern South Dakota along the North Dakota border, forming part of the state’s sparsely populated Prairie Coteau–to–plains transition into the northern Great Plains. Established in the early 20th century during the region’s homesteading and railroad-era county organization, it developed around dryland farming and open-range ranching. Perkins County is small in population, with only a few thousand residents, and settlement is dispersed across small towns and agricultural land. The county’s landscape is characterized by rolling prairie, rangeland, and seasonal waterways typical of the semi-arid plains, with land use dominated by cattle production and grain farming. Community life reflects a rural Great Plains setting, with local services concentrated in the county’s small population centers. The county seat is Bison, which functions as the primary administrative and service hub.
Perkins County Local Demographic Profile
Perkins County is located in northwestern South Dakota on the North Dakota border, with Bison as the county seat. It is part of a sparsely populated, largely agricultural region of the state.
Population Size
According to the U.S. Census Bureau’s data.census.gov portal, Perkins County had a total population of 2,835 at the 2020 Decennial Census (Perkins County, South Dakota).
Age & Gender
County-level age distribution and sex (gender) counts are published by the U.S. Census Bureau in the 2020 Census Demographic and Housing Characteristics File (DHC) and accessible through data.census.gov (table series commonly labeled “Age and Sex” for counties). The U.S. Census Bureau provides the official county figures, but specific age-bracket percentages and sex ratio values are not presented here because exact table extracts were not available within this response context.
Racial & Ethnic Composition
Official county-level race and Hispanic/Latino origin counts are published by the U.S. Census Bureau and accessible via data.census.gov, including 2020 Census tables that report:
- Race (alone or in combination, depending on table selection)
- Hispanic or Latino (of any race) vs. Not Hispanic or Latino
Exact Perkins County race/ethnicity counts and percentages are not provided here because the specific county table outputs were not available within this response context. The U.S. Census Bureau tables on data.census.gov are the authoritative source for these figures.
Household & Housing Data
The U.S. Census Bureau publishes county-level household and housing measures through the 2020 Census DHC (for basic household/housing counts) and the American Community Survey (ACS) 5-year estimates (for characteristics such as household type, occupancy, and housing tenure). These Perkins County statistics are accessible via data.census.gov. Exact household totals, average household size, occupancy/vacancy, and owner/renter counts are not included here because the necessary county table extracts were not available within this response context.

Email Usage
Perkins County, in northwestern South Dakota, is large and sparsely populated, which tends to increase last‑mile network costs and can limit high‑speed options; these conditions shape how reliably residents can access email compared with urban areas.
Direct county-level email usage rates are not generally published, so broadband and device ownership are used as proxies for likely email access. The U.S. Census Bureau’s American Community Survey (ACS) provides county estimates for household broadband subscriptions and computer ownership, which indicate the share of households positioned to use webmail or app-based email at home.
Age structure influences adoption because email use typically tracks internet familiarity and work/education needs. County age distribution from the ACS demographic profiles can be used to contextualize demand; a higher share of older residents is commonly associated with lower overall uptake of online communication tools.
Gender distribution is available from the ACS, but it is generally a weaker predictor of email adoption than age and connectivity.
Infrastructure constraints are reflected in rural service availability and provider coverage summarized by the FCC National Broadband Map.
Mobile Phone Usage
Perkins County is in northwestern South Dakota along the North Dakota line. It is predominantly rural, with small population centers (notably Lemmon) and large areas of agricultural land and prairie. Low population density and long distances between towers are structural factors that tend to reduce the consistency of mobile signal coverage compared with urban counties, particularly for higher-frequency 5G deployments and for indoor reception in sparsely served areas.
Key distinction: network availability vs. household adoption
Network availability refers to where mobile carriers report that service exists (coverage footprints, advertised technologies such as LTE/5G). Household adoption refers to whether residents actually subscribe to mobile service and use mobile internet (and whether mobile is their primary connection). These measures are not interchangeable; availability can exceed adoption where cost, device access, or service quality constraints limit take-up.
Mobile penetration or access indicators (county-level availability and limits)
- Direct county-level mobile subscription (“penetration”) rates are not consistently published as a single official statistic. The most widely used public sources provide:
- Availability/coverage (reported by providers and compiled by regulators), rather than subscriptions.
- Broadband adoption (often focused on fixed broadband subscriptions) and some survey-based indicators of internet access, which can include cellular data access but are not always reported at the county level in a way that isolates Perkins County.
Publicly accessible indicators relevant to Perkins County include:
- FCC Broadband Data Collection (BDC) mobile coverage maps for provider-reported availability by technology (LTE, 5G variants). The FCC’s map is the standard federal reference for availability, but it does not measure adoption and reflects provider filings rather than independent drive-test performance. See the FCC’s National Broadband Map.
- U.S. Census Bureau survey tables (American Community Survey) can describe internet subscription types and device access, but “cellular data plan” and device-type measures are typically more robust at state or larger geographies than for small counties, and margins of error can be large for sparsely populated counties. See Census.gov (American Community Survey) and data.census.gov.
- South Dakota’s statewide broadband planning resources provide context on rural connectivity constraints; county-specific mobile adoption figures are not consistently published in a single official series. See the South Dakota broadband office.
Mobile internet usage patterns (LTE/4G and 5G availability)
4G/LTE availability (network availability)
- LTE is generally the foundational mobile broadband layer in rural South Dakota, including counties such as Perkins, because LTE’s coverage characteristics and tower spacing are more compatible with large rural service areas than higher-frequency 5G.
- For Perkins County-specific LTE availability, the most authoritative public reference is provider-reported LTE coverage on the FCC National Broadband Map. This shows reported outdoor coverage by carrier and technology, but does not quantify signal quality, congestion, or indoor coverage.
5G availability (network availability)
- 5G in rural counties is commonly limited in geographic extent compared with LTE, and where present is often concentrated near towns and along major travel corridors. The FCC map distinguishes 5G technology types (as reported by providers), which can matter because low-band 5G can cover larger areas than mid-band or mmWave.
- Perkins County-specific 5G availability must be taken from the FCC National Broadband Map or carrier coverage disclosures; no single public county report consistently summarizes 5G presence, extent, and performance for Perkins County.
Usage patterns (adoption/behavior) and limitations
- County-level statistics isolating “mobile internet usage” (frequency, primary vs. secondary access, data plan reliance) are not reliably published for Perkins County in standard public datasets. National and state surveys show widespread smartphone and mobile internet use, but translating those patterns to Perkins County requires caution due to small-sample uncertainty and rural infrastructure variability.
- Where fixed broadband is limited or costly in rural areas, mobile service can function as an important connectivity option; however, no definitive public county-level measure consistently quantifies how many Perkins County households rely on mobile as their primary connection.
Common device types (smartphones vs. other devices)
- Smartphones are the dominant device type for mobile network access nationally and statewide, but county-specific device-type splits (smartphone vs. basic phone vs. hotspot-only devices) are generally not published as definitive statistics for Perkins County.
- The Census Bureau provides some survey-based measures related to device access and internet subscription types (e.g., households with a cellular data plan, households with a smartphone), but for sparsely populated counties these estimates can carry high margins of error and are not always available in a county table that cleanly isolates Perkins County. Reference points include data.census.gov and the American Community Survey documentation.
Demographic and geographic factors influencing mobile usage and connectivity
Geography, settlement patterns, and infrastructure economics (availability)
- Low population density increases per-user infrastructure costs, often leading to fewer towers per square mile and greater reliance on lower-frequency spectrum bands for broad coverage.
- Long travel distances between communities and reliance on state and U.S. highways elevate the importance of corridor coverage rather than dense in-town small-cell deployments.
- Terrain and land cover (open prairie with gentle relief) can support longer-range propagation than heavily forested or mountainous terrain, but large cell sizes can still produce coverage gaps and variable indoor reception due to distance and building penetration losses.
Demographics and service demand (adoption)
- Rural counties often have older age profiles than urban areas, which can correlate with different device ownership patterns and different intensity of mobile internet use. This relationship is commonly documented in broader state and national surveys, but Perkins County-specific adoption-by-age statistics for mobile service are not typically published in a definitive county profile.
- Household income and affordability influence adoption of higher-cost unlimited plans, newer 5G-capable devices, and backup connectivity (mobile hotspot plans). Public datasets more often characterize these factors at broader geographies than at the county level with stable precision.
Primary sources for Perkins County-specific verification
- Mobile availability by technology and provider (LTE/5G): FCC National Broadband Map
- Population, housing, and survey context (including some internet/device indicators where available): data.census.gov and American Community Survey (Census.gov)
- State broadband planning context and program documentation: South Dakota broadband office
- Local geographic and administrative context: Perkins County, South Dakota (official website)
Data limitations (explicit)
- No single authoritative public dataset provides a definitive “mobile penetration rate” for Perkins County in the way that national “mobile subscriptions per 100 people” metrics exist for countries.
- FCC coverage maps measure reported availability, not adoption or consistent user experience, and they do not directly capture indoor performance, speed variability, or congestion.
- Survey-based adoption/device estimates at the county level can be suppressed, unavailable, or statistically noisy for sparsely populated counties, limiting the ability to produce precise Perkins County-only smartphone vs. non-smartphone breakdowns or mobile-only household shares.
Social Media Trends
Perkins County is a sparsely populated county in northwestern South Dakota along the North Dakota border; its county seat is Bison. The local economy is strongly tied to agriculture and ranching, and day‑to‑day life is shaped by long travel distances between towns, a small population base, and reliance on regional hubs for services—factors that tend to concentrate social media use around mobile access, community updates, and marketplace-style communication.
User statistics (penetration / active use)
- No county-specific “active social media user” estimate is published routinely by major survey programs; most reliable measures are available at the U.S. and state/rural level rather than for a single rural county.
- Nationally, about 7 in 10 U.S. adults use social media (a commonly cited benchmark for overall penetration). Source: Pew Research Center social media fact sheet.
- Rural vs. urban context: Social media use is widespread in rural areas but generally lower than in urban/suburban areas, and rural connectivity constraints can shape usage patterns (more mobile-first behavior, less video streaming where bandwidth is limited). Source: Pew Research Center: Mobile Technology and Home Broadband.
Age group trends (who uses social media most)
County-level age-by-platform splits are not reported by the major U.S. survey series, but the strongest, consistent pattern relevant to Perkins County follows national age gradients:
- Highest usage: ages 18–29 (highest adoption across most major platforms).
- Middle usage: ages 30–49.
- Lower usage: ages 50–64, with 65+ lowest overall, though usage among older adults has increased over time.
- Source for age patterns across platforms: Pew Research Center social media fact sheet.
Gender breakdown
- Gender differences are platform-specific and measured reliably at the national level (not county level). Typical patterns reported by Pew include:
- Women more likely than men to use Pinterest and somewhat more likely to use Facebook.
- Men somewhat more likely to use platforms such as YouTube in some survey waves; many platforms show small or inconsistent gender gaps.
- Source: Pew Research Center social media fact sheet.
Most-used platforms (with percentages where possible)
Robust platform shares are available nationally; these are the best “percent using” benchmarks for a rural county context where local measurement is limited:
- YouTube and Facebook typically rank as the most-used major platforms among U.S. adults, with Instagram next tier and TikTok/Snapchat skewing younger.
- For current platform-by-platform percentages (U.S. adults), see: Pew Research Center platform usage tables.
- Platform use is often higher on mobile in rural contexts due to coverage gaps and fewer fixed broadband options. Source: Pew Research Center: Mobile and broadband adoption.
Behavioral trends (engagement patterns and preferences)
- Community information and local commerce: In small-population rural counties, social platforms tend to be used heavily for local announcements, events, school/sports updates, weather and road conditions, and buy/sell/trade activity, with Facebook (including Groups and Marketplace features) often serving as a generalized community bulletin board.
- Messaging and “private social”: Sharing and coordination commonly shift toward direct messages and small groups rather than broad public posting, aligning with national findings on how people use social platforms for personal connection and community ties. Source: Pew Research Center: Social media use in 2021.
- Video consumption: Short- and long-form video (especially on YouTube, and increasingly via short-video features on other platforms) is a major engagement mode nationally; in rural areas this can be moderated by bandwidth constraints and data-plan considerations. Source: Pew platform usage and format trends.
- Age-driven platform preference: Younger adults concentrate engagement on Instagram, TikTok, and Snapchat, while Facebook remains comparatively stronger among older cohorts; this produces cross-generational platform separation in many communities. Source: Pew age-by-platform usage.
Family & Associates Records
Perkins County family and associate-related public records primarily include vital records (birth and death), marriage and divorce records, probate/court files, and property instruments that can evidence family relationships (deeds, mortgages). In South Dakota, birth and death certificates are maintained by the state rather than counties; certified copies are issued by the South Dakota Department of Health, Vital Records (SD Vital Records). Adoption records are generally handled through state courts and are restricted; access is not provided through open public databases.
Publicly searchable databases for Perkins County commonly relate to recorded land documents and tax/parcel information. The Perkins County Register of Deeds maintains real estate recordings and related indexes; access is provided in-person and through any online services the office makes available (Perkins County Register of Deeds). Court records (including divorce, protection orders, and some probate filings) are part of South Dakota’s unified court system; online access is typically through the state judiciary’s public access portal (South Dakota Unified Judicial System).
In-person access is available at the Perkins County Courthouse offices in Bison during business hours (Perkins County official website). Privacy restrictions commonly apply to vital records, adoption files, and certain court matters; public inspection is generally limited to non-confidential filings and recorded instruments.

Education, Employment and Housing
Perkins County is in northwestern South Dakota on the North Dakota border, with its county seat in Bison. It is a sparsely populated, agriculture-oriented county characterized by small towns and large rural areas; access to services, schools, and jobs is strongly shaped by long travel distances and regional hubs outside the county.
Education Indicators
Public schools (count and names)
- Perkins County’s public K–12 education is primarily provided through small district(s) serving Bison and surrounding rural areas. A commonly cited local system is Bison School District (Bison).
- A single consolidated K–12 building is typical for counties of this size; however, an authoritative, up-to-date school list by building name was not consistently available across public datasets at the county level. For the most reliable current roster, refer to the South Dakota Department of Education district directory via South Dakota Department of Education and the district’s official site.
Student–teacher ratios and graduation rates
- Student–teacher ratio: County-specific ratios are not consistently published as a standalone indicator. In very small rural districts in northwestern South Dakota, ratios often fall in the mid-teens (students per teacher) due to small class sizes; this is a regional proxy, not a county-measured statistic.
- Graduation rate: County-level graduation rates are typically reported by district or school rather than by county. South Dakota’s statewide graduation rate is commonly reported in the mid-to-high 80% range in recent years; county-specific graduation rates should be taken from district/school report cards (district-level source: South Dakota School Report Cards).
Adult educational attainment
- Perkins County has historically tracked below statewide averages on college attainment and near-to-slightly-below on high school completion, reflecting its rural workforce profile.
- County-level, most-recent adult attainment figures (share with high school diploma or higher; share with bachelor’s degree or higher) are best sourced from the U.S. Census Bureau’s American Community Survey (ACS) county tables. The most accessible county profile is available through data.census.gov (search “Perkins County, SD educational attainment”).
Notable programs (STEM, CTE, AP)
- In rural South Dakota districts of this size, Career & Technical Education (CTE) offerings (e.g., ag mechanics, welding/industrial arts, business, family and consumer sciences) are common, often coordinated through regional services or multi-district cooperatives; agriculture education/FFA is also typical.
- Advanced Placement (AP) and specialized STEM coursework may be limited by staff size and enrollment; dual-credit coursework through regional colleges is a common substitute in similar rural districts. Program availability varies by district and year and is best verified through district course catalogs and the state report card.
School safety measures and counseling resources
- South Dakota districts commonly use building access controls, visitor sign-in procedures, emergency drills, and coordination with local law enforcement as baseline safety practices; specific measures are typically documented in district policy manuals and school handbooks.
- Counseling capacity in very small districts is often limited compared with urban areas (frequently a shared counselor serving multiple grade levels). State and regional supports are coordinated through education service agencies and the state DOE; district staffing details are generally posted in district directories and report-card staffing sections.
Employment and Economic Conditions
Unemployment rate (most recent year available)
- County unemployment is published through the U.S. Bureau of Labor Statistics (BLS) Local Area Unemployment Statistics. Recent-year unemployment in western South Dakota counties with similar profiles typically remains low-to-moderate relative to national levels, with seasonal variation tied to agriculture and construction. The definitive county figure is available via BLS LAUS (select Perkins County, SD).
Major industries and employment sectors
- Agriculture and related services form the economic base (ranching, dryland farming, farm support services).
- Local government and education (county government, schools) and healthcare/social assistance are key stable employers in small counties.
- Retail trade and accommodation/food services are present at a small scale in Bison and along regional travel corridors.
- Additional employment often comes from construction, transportation/warehousing (including farm supply logistics), and resource-related services in the broader region.
Common occupations and workforce breakdown
- The occupational structure typically skews toward:
- Management and business (farm/ranch operators, small business owners, public administration)
- Transportation and material moving (truck driving and equipment operation)
- Construction and extraction (construction trades; extraction varies regionally)
- Sales and office (small retail and local services)
- Healthcare support and practitioner roles at local clinics/regional hospitals (often outside the county)
- Education roles (teachers and support staff)
- A precise county-by-occupation breakdown is available through ACS occupation tables on data.census.gov.
- The occupational structure typically skews toward:
Commuting patterns and mean commute times
- Perkins County commuting patterns are shaped by long distances and limited in-county job variety. Out-of-county commuting to larger regional centers is common for healthcare, skilled trades, and some government/industrial jobs.
- Mean commute time: Rural Great Plains counties frequently show mean commute times around the high teens to mid-20 minutes; this is a regional proxy. The definitive county mean commute time and commuting mode split are available in ACS “Commuting (Journey to Work)” tables on data.census.gov.
Local employment vs. out-of-county work
- A notable share of residents often work outside the county due to limited in-county employers. Employment inflow/outflow and workplace location can be quantified using the Census Bureau’s OnTheMap/LEHD tools: OnTheMap (commuting flows by home and work geography).
Housing and Real Estate
Homeownership rate and rental share
- Perkins County is predominantly owner-occupied, consistent with rural South Dakota’s housing profile (single-family homes and farm/ranch residences). County-specific owner/renter shares are reported in ACS tenure tables at data.census.gov.
Median property values and recent trends
- Median home value in very rural western South Dakota counties is typically below the U.S. median, with price trends influenced by interest rates, limited inventory, and variability in local employment. County-specific median value (owner-occupied) and time series are available via ACS and the Federal Housing Finance Agency (FHFA) house price data (broader-area index): FHFA House Price Index.
- Local sales volumes are low; individual transactions can shift medians more than in urban markets.
Typical rent prices
- Rental supply is limited and concentrated in Bison and small multifamily properties. County median gross rent is available in ACS “Gross Rent” tables on data.census.gov. In counties with constrained rental inventory, advertised rents can vary widely and may not track smoothly year to year.
Types of housing
- Single-family detached homes dominate in town and rural settings.
- Farm/ranch housing and rural lots represent a significant share of the occupied housing footprint.
- Small multifamily buildings and a limited number of apartments/duplexes provide most rental options; manufactured homes may appear in the housing stock as in many rural Great Plains areas.
Neighborhood characteristics (proximity to schools/amenities)
- In Bison, residential areas are typically close to core civic amenities (school campus, courthouse/county offices, basic retail, community facilities). Outside town, housing is dispersed, and access to services depends on highway travel to Bison or regional centers.
Property tax overview (rate and typical homeowner cost)
- South Dakota property taxes are administered locally with state-set frameworks; effective tax rates in rural counties are often around ~1.0% to ~1.5% of market value as a broad statewide/rural benchmark, but liabilities vary by classification and levies.
- The most authoritative county and statewide summaries are published by the South Dakota Department of Revenue: South Dakota Department of Revenue property tax overview. Typical homeowner tax bills in Perkins County align with its generally lower home values, producing lower absolute annual taxes than metropolitan counties, even when effective rates are similar.
Data availability note: Several indicators requested (school-by-school lists, student–teacher ratios, and graduation rates) are most reliably reported at the district/school level rather than as a county aggregate. The most current county estimates for attainment, commuting, tenure, value, and rent are consistently available through the U.S. Census Bureau ACS on data.census.gov, while unemployment is best sourced from BLS LAUS.
